uuum this is a weird glitch i haven't seen before but i just got on dayz and my mouse is invisible.... i can't play until i fix this because if i need to bandage or something i can't see my mouse so i can't find my rags. i'm going to try to restart my pc but this is awkward 


it fixed itself when i restarted my whole pc. i just shut it off for a few minutes and then turned it back on

If you will have this issue again, contact me please.

I'm sure this is already well known as it's been around for a long time in one way or another, but the frame loss whilst driving seems to be related to the wheels: To demonstrate, watch your FPS counter whilst driving. Focus your camera towards the wheels and then cut them out of shot and you'll see what I mean.

I suspect the tracks (why are there even tracks on the tarmac?) left by the vehicle.

I start with my usual 90ish FPS.

After driving around the map, the frames get lower and lower, resulting in 7 (SEVEN) FPS.

Restarting the game gets me high frames again, which then get as low as 7 when I ride a vehicle, don't really need to drive.


A little test I did with my friend:

Was driving for a while, at half of my FPS.

Picked up my friend who reported no frame loss.

After several kilometers, my game has become unplayable while his was already losing frames.

I restarted, everything was fine while he went slideshow.


Next example - we crashed, bus got stuck at a bollard, leaving rear wheels above surface with no contact.

Speedometer showed 60km/h, yet there was no frame loss as the vehicle was not moving.

Had 2 times a mix of desync, rubberbanding and gettin pushed to one side constantly for a few seconds. But not in a car.

I had this same experience. I was getting pushed and stuttery while I was avoiding zeds.

I can't decide if i think it's just time driving or if the vehicles are leaving Donnie Darko-like traces around the map; as it seems to get worse faster if I drive the same route repeatedly.  Maybe it has to do with getting in and out of the vehicle repeatedly.  Or vehicles crossing each others/own paths.  A few builds ago a few of us actually summoned a "dead spot" on NWAF by racing around it repeatedly.  When you drove into this spot, the game just froze.

Stay out of Thurman's tents, you mooks!


I had a long evening/night session, no crashes until I tried to close DayZ from the red X on the task bar.

Nice to meet @MamaB3ar, glad we could help you get off the coast, and glad to have the help working on these Experimental builds.

I hope I don't forget anyone so here goes, emu, Thurman, starvingart, IMT, Luc, MamaB3ar, sanguine, GirthBrooks, Hell, and myself gathered vehicles and tents while intermittently fighting wolf packs. We also made contact with a recurring player on the server who will likely join us in the future, Bubba.

*I believe Buckshot at range should be more effective and possibly have less dispersion at 50 meters.


A feast of wolves slaughtered by art after picking up MamaB3ar.




^That moment when you go to screenshot the action as your friends attack Rocket only to take a screenshot of the moment he hits you after switching aggro.


^MamaB3ar stands proud over our kill.


^A hot cooking pot smolders through the floor of the bus when held in inventory.




^Brooks flips out in a V3S, which then clips through map....






^MamaB3ars hands bugged in that awkward flat side of axe facing glitch pose....

Speaking of shotguns, hell and I had an encounter with a player tonight.  The stable maintenance crowd flooded the Experimental servers as usual, and one of them found his way behind hell in a tree.  Long story short, Hell had a lot of head accessories to soak up damage, and the shotgun failed to kill him.  Cleaned-up hostile, and revived Hell.

*I believe Buckshot at range should be more effective and possibly have less dispersion at 50 meters.

Some info on buckshot:

Buckshot currently has the following stats:

hit = 6
hitShockHead = 20000;
hitShock = 400;
hitBlood = -200;
hitHealth = -200;
bleedChance = 2;
airFriction = -0.00096;
initSpeed = 404;

So first off, hit value, the main damage figure. It sits just above the .380 ACP. The 'standard' American ballistics for .380 FMJ are 95 gr, .355" bullet at 955 ft/s from a 3.75" test barrel, the muzzle energy is 192 ft lb. A single pellet of 00 buckshot (.33" diametre) weighs about 54 gr and gives a nominal 1,325 ft/s from a 30" test barrel, for 210 ft lbs of energy. They both have adequate penetration (20+ inches in bare gelatin). So, the damage value is placed appropriately relatively speaking, maybe a bit high, but it has less hitBlood (-200) and slightly less hitShock (-400) than regular bullets, which (all except the .22 LR) have -500. The hitShockHead and bleedChance values are the same. So with those complicating factors it's tough to say. 

The main problems:

The airFriction is too low, it's a copy-paste, probably unintentional, from the 7.62x54R. So this gives the DayZ buckshot a G1 ballistic coefficient of around .45 over 50 m... for comparison the .308 M80 (real life) is about .39, the 5.56 SS109 is about .30, etc... pretty silly (edit: for comparison, real life 00 buckshot would be approximately 0.04 G1, although that drag model is not appropriate). The airFriction for a 00 buckshot pellet should actually be around -0.008! A pellet of buckshot is the ballistic equivalent of a Wiffle ball. Lead round balls bleed off their speed horribly. At 50 m a 00-size pellet starting at 1,325 ft/s has lost well over half its energy. That will lower downrange damage in DayZ, but since that's based on v/v0 and not (v/v0)² it won't be too terrible.

Patterning: the old rule of thumb is that buckshot spreads at 1" per yard. Like most rules of thumb it's just a very rough estimate and the actual patterns depend on the type of buckshot, the gun, choke, etc. Rule of thumb tends towards the larger sizes at typical distances (25 yards or less). Anyways, for comparative purposes, one inch per yard comes out to 1.59 degrees. The shotguns in DayZ have a 3 degree spread (6 degrees for the sawn-off IZH43). Within the typical effective range, the outside dimensions of the patterns are significantly larger than real life, particularly for the sawn-off version. 

Here's one test of various makes by Shooting Illustrated


But shotguns in DayZ have a semi-fixed pattern and fire 11 pellets (as opposed to the standard 9-pellet, 2-3/4" 00 load). The DayZ pattern consists of one central pellet and two rings. The outer ring has six pellets and the inner ring, four. The impacts are fairly evenly spaced. Not very realistic and needs extra consideration.


Here's an example pattern placed on a running figure. The left pattern is the spread of MP133s and the full-sized IZH43 at 25 m. The right pattern is the spread of the sawn-off IZH43 at 25 m, or the spread of the other three shotguns at 50 m.



After a certain range the outer six pellets are completely useless, but the inner five stay useful to a good range. The shotgun has a large dispersion (which is a separate value from that which dictates pattern size), so the central pellet is not accurate (3 foot circle at 100 yards). However, that's still accurate enough to have a good chance of using that pellet to hit an exposed target at surprising distances, if you aim.

Wait, why is it my fault the thread is open? You can't read for yourself? Posting at 1am I can hardly be blamed for merely opening the thread I saw active.... GG in the filthy stable casul kill.

Man, I wish you had witnessed the shot I took on a retreating wolf. At about 50m you could clearly see the impacts, which for the moment completely obscured the wolf model but somehow every shot pellet seemed to miss, no stagger, no whimper, no red.... it's possible I couldn't see the hit but I doubt it.


Awesome post.

I'm glad to hear that they seem to have at least gotten a close to accurate reproduction of shotgun performance with current placeholder settings.

I would personally very much like to see a full range of shotgun shells from salt to slugs.

      Hello Survivors! 
      We were almost ready to push 0.62 to Experimental branch today, but yesterday's play test led us to a discovery of several issues that we thought were still worth looking into. 
      To be more specific, the most problematic issue is the wrong representation of door states between client/server. See the GIF below:

      We're now working on a fix, and we have discovered the revision in which this bug was introduced, but as we want to avoid pushing any releases on Fridays due to potential issues with deployment, we won't make 0.62 available on Experimental branch this week. 
      We thought you'd appreciate the heads up before you make your weekend plans, and we're hoping to show you the updated Chernarus very soon!

      This week, Brian is addressing how walkie talkies in DayZ are the new server-wide chat. Eugen is touching upon the complexity of DayZ, as well as some of the recent tasks of the entire team. We also feature Peter who shares exciting news about changing the inner workings of loot spawns (this will be an extra crunchy topic for any future DayZ modders out there!) Next up are our map designers Mark and Adam, and yes, they have some screenshots for you this time! 
      To finish it all in style, Baty is sharing a couple of photos from our trip to the real Chernarus, where we were filming the upcoming Q&A video last week. Let's get to it, it's a long one folks, but full of great development news!

      Dev Update/Hicks
      The last time we spoke I mentioned discussing the impact of sway, and the implications on gameplay. I think one of the overlooked aspects of replacing the animation system, and legacy player is the fact that this isn't just a "change" in how sway / hold breath, and the likes behave. With the legacy setup, early on Peter and I both supported adjustments to try and refine where it was sitting as an experience in game. Pretty rapidly we realized that where we wanted it to be, and what the technology would allow us to do were two things very much apart. Rather than wasting development time trying to iterate and iterate upon a system that was slated to be replaced, the focus was placed on functionally where we wanted to be with the final product.

      Its important to understand that as I said earlier - this isn't just a change. This is a replacement of the technology and player - so the old methods for sway, stamina, and such are gone. As we move towards beta, and start getting those builds into the hands of players - then we can refine the new methods of sway, and get it to a point in which you still need to be aware of your stance, weight (hopefully!), and the amount of sprinting you are doing - but that it is entirely manageable and does not feel like this daunting and overwhelming rigid inflexibility it can become in some situations with the current legacy Steam builds.
      In addition to this, Peter and I have also been spending some time discussing the implication of server wide chat (specifically VOIP). I've noticed aside from strong private shard communities like DayZ Underground - folks don't seem to be utilizing radios in game. While on servers such as that, I find the communication across the map with random players occurs far more often. Personally, I'm a firm supporter of radios being starting gear so that every player can opt-in to server wide communication should they choose it - but I'm still working on converting Peter to this mindset. One of the limiting factors I've noticed the community discussing is the rate at which radios consume batteries, and the hunt for batteries themselves being both unrewarding and difficult.

      I know a lot of folks have expressed a desire for the old global chat (which personally I do not miss at all) - and some have also expressed an interest in the old kill feed. A default on global chat is just not something we ever felt had a place in DayZ. That said, it can easily be turned on for mod authors, a kill feed as well shouldn't be difficult to put together.

      For Peter and I - the immersion of the radios themselves, paired with the fact that they effectively serve as an opt-in global VOIP, is incredibly attractive. As I'm sure you all recall - we increased their range greatly several builds back. Aside from availability of the radios themselves, and consumption of batteries, I think they represent where we'd like global VOIP to be. So I encourage you all to utilize them more, so I can convince Peter that they should totally be player starting gear.
      C'mon - do it. You never know who will be on the other end.

      Hey guys! First things first, I want to share the conclusion to the story I mentioned here the last time! We managed to fix the crash - yay! This means that everything seems to be in place for 0.62 on Experimental and I can't wait for you guys to play with the new environment visuals and sounds. There is still space to improve and make things more distinct, but the work does not stop there after we send 0.62 to Experimental/Stable. It's the first step to get visuals and audio where one would expect them in 2017.
      To continue with stories from the development front, large part of our daily routine here is planning for BETA, and doing recaps with the aim to refocus the development, structuring our team into smaller feature teams. In the last two weeks, we revisited mind maps of these feature blocks to set up a core functionality of DayZ - starting with larger ones, and working our way down to smaller, more actionable items that we can "close" as development items.
      DayZ is a complex game. It's a system sandbox where its gameplay loop starts working only when all the small details are in, and start interacting with each other. It's one of the hardest genres to iterate upon, as you can't structure the features easily, and every single thing can break the gameplay ecosystem. I highly recommend the original Deus Ex postmortem that was featured at GDC 2017 by Warren Spector himself.
      If you separate the work we have done over the years, you can simplify it into three layers: engine, data and gameplay. Engine is the core base and modules upon which we want to build this game, data are visual assets (e.g. models) or audio that support the features, and gameplay is represented in both code and script. That’s why we have technical designers writing script, and gameplay programmers doing the same for the DayZ codebase.
      Over the course of the last two years, these two groups (programmers and scripters) have been focused on closing core support systems for the architecture of gameplay in the new engine, and haven't had the chance to see their individual parts of the game work together. It's exciting now that what you could previously see only in a debug mode, or under parameters for internal client, is now finally able to support actual gameplay, and can be seen inside the game in a broader context. It’s a start of something much bigger for everybody in here.
      Instead of focusing on systems and technology, we are finally making a game. The core gameplay loop is our focus now, split into melee combat, ranged combat, player character and its interaction with the world, and the infected (and their interactions with the world). All these pieces we have been building are slowly getting playable. There are still hurdles along the way and ahead of us - but that’s how development works.
      What we're doing now is obviously one of the most critical parts of DayZ development, but all these previous decisions to create tech first, and focus on enjoyable experience later, are going to benefit the game (and gameplay) in the long run.
      To give a glance at the currently open development items in our teams :

      • AI script implementation
      • Zombie behavior script representation
      • Inventory and item conditions
      • Item spawn definition

      In regards to Central Economy, there were some changes made in terms of loot spawning and its definition for BETA version that we are working on. Till now, loot placement was defined directly as specific point per one item in .p3d files, grouped in named selections (which are paired with categories and tags in configs and areas in area map later). There has been a need to pay close attention to dimensions of given items against each other, and available space around them to avoid unnecessary clipping between items, or between item and building itself.
      This process was tedious as it lacked sufficient spatial orientation in object editor, leading to prolonged time needed to populate a building (for example, the school building has tens of thousands of spawn points defined in the old system). Not to mention that packing and exporting proxies was mandatory in order to be able to see new/adjusted spawn points working in game, stretching the time even further. You can see how it was set for the police station on the screenshot below. 

      Instead of exact points, the new loot placement uses ranges. Range simply defines a circular area within which item can be spawned. During placement of these ranges, they are checked against each other and building itself in real time. This approach avoids any clipping and collisions of items during spawning. Placement output is stored as XML directly in the mission folder, so it's very convenient for modding, it also can be loaded and edited.
      The best part of this new system is that it's completely defined and visualized directly in game, from free-fly camera. Additionally, everything is real time, which (coupled with independence from addons) cuts down the time required for setup dramatically.

      After introduction of this new system, we managed to get from more than 1.000.000 spawn points (mind that was after massive reduction for 0.61 version from 4.000.000+ spawn points) to current ~130.000 used, and at the end, what matters the most is the increased server performance.
      Don't waste time doing unnecessary things... see you in Chernarus folks!
      - Peter Nespesny / Lead Designer
      Dev Update/Mark
      Hi everyone, Mark Gill here! I'm one of the map designers who has done many tasks for Chernarus, but more recently I've been focused on developing the new Chernarus forests for this 0.62 visual upgrade. This has been a lengthy, challenging, but also rewarding process. I will try to share some of the thought process behind the changes that were made.

      With the new forest overhaul, we hope the survivor experience in DayZ will be greatly enhanced. We tried to make traveling through forests a more immersive experiance. Repetition can quickly become boring on a map of our scale, so as you traverse through forests across the map, the visuals will change at a fairly rapid pace. This was a large undertaking, but it was important to keep the visual stimuli changing in unpredictable ways.

      We were able to increase the number of tree variations thanks to our talented artists to create types of forest that display different characteristics. The overall shape, size, and canopy development gives sections of forest a sense of age. These sections can vary from close spacing of younger variants. to farther spacing of older variants. There are limits to density due to the performance impact, but hopefully the amount of variables at play will keep you on your toes as you travel across the map.

      Broadleaf hedgerows and forest edges now have a lower profile than in the past. This looks more natural and adds more coverage at a lower height. With this change, sections of forest are more self-contained with this "bushier" egde-line. This helps block some sight in and out of deep forest. While much thinner then reality, this balanced result is an important improvement to the visuals as well as gameplay. Moving as an individual or group in and out forest should be a more significant shift as well as hiding. While you may feel safe and hidden within deep forest sections, there is also the opposite of not knowing who may be nearby.

      We hope you will enjoy your freshly upgraded playground!
      - Mark Gill/ Map Designer
      Dev Update/Adam
      Hello everyone, I hope that you enjoyed this SR's contribution from Mark, our map designer, who has showed a great passion for such whopping task as transforming the nature of Chernarus is. He spend countless amount of time designing and configuring how the new forests and individual vegetation looks and we are all excited for the day when you finally be able to experience new Chernarus too.
      We are currently really busy with map tweaking to make sure we can deliver the new Chernarus in best possible shape we can in given time. Please keep in mind that update .62 has touched almost every corner of Chernarus and while we do our best to make sure everything will look just like we wanted, there will be some minor map-related issues. Also, keep in mind that update .62 contains initial changes to the whole western border, completely getting rid of old terrain and object layout and replacing it with much more detailed landscape and layout. This work, labelled as western expansion, is however split into several phases and more additions and fixes are planned for later updates.

      In addition to many great improvements to the way grass, trees look and behave in wind, our programmers also went and fixed many issues related to lighting and sky. One of the major things was that before 062, shadows were turned off too early / too late and that impacted the quality of scene (mainly interiors) in a very bad way. This issue was fixed along with many more (like smoother sky-fog transition, reduced size of the moon and sun, moon visibility, horizon look, and more...). These changes have enabled us to focus on lighting config for Chernarus, which saw some great changes. While we do not consider it to be final, we hope that it will prove to be a very fitting addition to the visual update coming with 0.62.

      Additionally, in January 24th SR I promised you that I will show you the new railway stone bridge, so here it is! Coming in 0.62 along with many additional changes to the railway network of Chernarus!

      See you in Chernarus!
      - Adam Franců / Senior Map Designer
      Community Spotlight
      Last week, together with our Brand Manager Martin and our external camera crew, we embarked to the real world model for Chernarus to shoot a new Q&A video with our Map Designer Adam Franců a.k.a Sumrak (a well known Arma 3 modder). The real Chernarus is found in the vicinity of the town of Ústi nad Labem in the Czech Republic and we already talked about it in the March Status Report. 
      As a first thing we aimed for the "Pik Kozlova" (or Kozí vrch in the real world), which offers beautiful view of the outskirts of Ústi nad Labem that you most likely know from the game as Chernogorsk. Even from such distance, you can recognize typical blocks of flats in Chapaevsk, Novoselky and Dubky, where you surely more than once encountered camping snipers. The real Chernarus does not have a sea, because we don’t have any in the Czech Republic, but you can recognize the shore as the curve of the river Labe. I have snapped a couple of photos for you to compare the “real Chernarus” and it's game counterpart as shown in update 0.62.
      Comparison of Ústi nad Labem and Chernogorsk:

      Later on, we moved to Lipová, which was the original village you know as Starý Sobor. It has the characteristic red barn and two large abandoned cowsheds. I looked behind the buildings, where the military tents are supposed to be, but of course they were not there. There is an area with concrete floor instead, where silage used to be fermented.

      Abadoned cowsheds:

      After Lipová, we travelled to village Javory, which can remind you of ingame Gorka. That is where the church is located, that you can see in many locations in the game. We wanted to have a look inside, but there was a sign saying “gassed, do not enter”, so we decided to not take the risk and after a bit of filming we left the town and headed for the Zub castle.

      If you used to run through Moglievka to Vyshnoye in game, you might have noticed ruins of the castle Zub on your left hand side. The castle is really there, at least its remnants, and it is called Blansko. It is slightly smaller than in game, but it provides an amazing view of the surrounding countryside. You can see the small village of Vyshnoye and its vicinity. The name of the real village is the same as of the castle – Blansko. And one point of interest - a community member Ivan tweeted to us that he hid a non-public geocache with DayZ motive nearby the castle. So if you will be around and manage to find it, let us know its content, because we are curious what is inside and we didn’t find it.

      It was an absolutely amazing experience for me, because I felt like I was really in the game. We did not need a map, we know Chernarus like the back of our hands, therefore we know exactly which way to choose and where everything is. If you will ever have the opportunity to visit Czech Republic, make sure not to miss this experience. I am definitely planning to go back to real Chernarus, this time on foot, with tent and some beans for couple of days, because it is worth it, will you join me?
      I hope you enjoyed my short report and I can not wait to show you the video we filmed there. If you were also on a trip through the real Chernarus, do not hesitate to show off and tweet to us what you liked the most and some of your pictures! Have a great time and see you in Chernarus, this time in game!
