Your guess was correct :) I went out and bought a 980ti (also not jst for DayZ) and i'm still dropping below 20FPS in cities. This game needs some multicore optimisation sooner rather than later :) I take it there is no way to force the game to take advantage of multi-cores?

Hi all, Has anyone got hold of a 980ti yet? I'm curious with reagrds to DayZ performance using that card. (while i'm at it - does this game take advantage of multi CPU cores yet?)

OK hyperthreading on or off does nothing for me. Changing the GPU frames appeared to do nothing either. I think I'll just have to be satisfied with what I've got (which is a lot better than it was. I can at least play the game :))

OK I shall go and change this to 4 and see what happens. *edit* No difference tbh. Away to turn off hyperthreading again now I'm in a town :)

So changing this: GPU_MaxFramesAhead=1000; to this: GPU_MaxFramesAhead=4; Is what you recommend? Why would it be set to 1000 in the first instance? :)

OK so I've ran about a bit with hyperthreading both on and off. Now, FYI, I'm somewhere hopelessly lost in the woods so this wasn't the best test by any means :) There appear to be no buildings/ towns for miles around... I think I found the edge of the game a few miles back... Settings are as follows: Objects: Normal Terrain: Normal Clouds: High Shadows: High Video Memory: Auto Texture detail: High Texture filtering: HIgh AA: Low Alpha to Coverage: Disabled Edge Smoothing: FXAA normal HDR: Low Ambient Occlusion: Enabled Post processing: High Resolution 1920 x 1080 (there was another resolution setting in the menu option and I had that also set to 1920 x 1080 - can anyone explain to me why there are 2x resolution settings?) With hyperthreading disabled I was getting between 55 and 70 fps in the woods. With hyperthreading enabled I was getting between 55 and 75 fps in the woods. I'll need to find a town somewhere and attempt this again to see if there are any gains to be had in an urban environment. Seems I actually lost 5 FPS (max) with hyperthreading disabled but this was hardly a scientific test by any means :) *edit* OK I commited suicide to get out of the end of the world. I've also tweaked the game files, options etc using this guide: http://steamcommunity.com/sharedfiles/filedetails/?id=216291078 (thanks ankiltareum) and went for the following: -cpuCount=6 -exThreads=7 (is this correct for an i7 5820k?) -maxMem=16384 -maxVram=3072 -nosplash -noPause and this: sceneComplexity=1000000; shadowZDistance=150; viewDistance=3000; preferredObjectViewDistance=1700; terrainGrid=3.125; and tweaked the various settings to mirror the guide (i.e. everything on very high except where instructed to drop). The results are interesting. I get between 45 - 60FPS in rural settings, between 29 and 35 FPS urban (and not big cities either - not found one yet, still running about). The only part of the guide I didn't understand was the bit about Max Frames Ahead and GPU_DetectedFramesAhead. The guide said to keep them both around 1 - 4. My default settings are: GPU_MaxFramesAhead=1000; GPU_DetectedFramesAhead=2; I'm a little unsure about dropping a setting from 1000 to between 1 and 4? I'm also still not sure what the difference between these 2 are: Resolution_W=1920; Resolution_H=1080; and Render_W=1920; Render_H=1080;

OK sorry for the delay. I'm off to check out the difference just now :)

I'll do a test tomorrow evening and report back :) Too late tonight

Yes I'm going to leave hyperthreading off for the time being ^ I remember something being said about high end machines requiring high settings in the Arma engine. Urban legend? Given the specs being thrown around here I'm not not satisfied with my performance. I'm going to have to play with the settings more indeed ;)

OK I've managed to get the FPS up to around 40(+) in towns and then between 70 and 100 in the open on medium settings. I guess my biggest performance gain was from the two options I adjusted in the Nvidia control panel (power usage and threaded optimisation I saw in another guide relating to performance). Hyperthreading was also off. PSU is an 800w Corsair. I'll go and tweak through some more settings and see what upping to high does just now. I'm very happy I can play the game though. Just found a gun :) *edit* Here is an image of my GPU load over the last session I just played. This is abnormal you think?:

OK so I reinstalled the Nvidia drivers (I assume a "clean" install is sufficient?) and no joy. Altering some of the Nvidia control panel settings appeared to make a slight difference, namely power usage (upped to MAX) and Threaded Optimisation set to "ON". This brought me up to around 30FPS in whatever town I was in dropping to 25 FPS. I can live with this (better than sub-20) if I have to but obviously not ideal. While I was doing this I logged everything via GPUZ and CPUZ so my findings are as follows on the off chance that some of this may be useful ( I have no idea)? GPU: Memory used didn't exceed 2000 MB during the entire logging period. Given that it's a 3072 MB card perhaps this is something? Clock speed was sitting at 1019.6 Mhz the entire time. Memory clock was sitting at 1749 MHz the entire time. GPU load appears to be all over the place, constantly jumping between a low of 50% and highs of 99% CPU: Core load (all 6 cores were active) never exceeded 41% and was on average below 30% on all cores. Is this normal? Core temps never exceeded 58 degrees Core speed on all cores was sat at 3399.71 MHz the whole time Hyperthreading was turned on. (What the hell is hyperthreading, do I need this ever or should I disable by default?) Anyways those are my findings so far. Settings in DayZ were medium default @ 1920*1080

Thanks for the reply ^ Makes me think something 'aint right here. Crysis 3 runs @ 60FPS on ultra (1920 x 1080) so I don't think the CPU is broken per-se but I am scratching my head here too :) Should've kept the old overclocked 2500K apparently for this game. I'm off to google. If I find anything i'll post back a possible solution *edit* OK - will try that and see what happens. The PC is a pretty new build so I wouldn't expect them to be an issue but i'll try anything just now.

OK I am on the case. *update* OK turning off hyperthreading didn't appear to do very much, perhaps a 7 FPS gain? Can I assume though that I should be seeing better performance than 20 - 25 FPS in a town?

Hi all, I realise that this is another performance thread but I just wanted to run something by you all. I've got an i7 5820k and a Geforce 780ti. I'm getting sub 20fps in (small) towns and generally get poor 40 fps performance out in the country. Doesn't matter what settings I tweak, performance is utterly terrible on low - high settings. Now I know, alpha and all that, but I used to have an i5 2500K (admittedly overclocked to 4.2 Ghz) and I wasn't getting performance hits like this. The game is almost unplayable (and it's a shame as it's one of my favourites). I suppose i'd like to know if this state is "par for the course" at this point (like new additions prior to optimisation have hammered performance globally) or if I have a problem. Any ideas?
