My PC is powerful, why do I get crummy FPS? (Especialy in cities)

a lot of people experience varied performance and there are lots times where someone with a lower spec ends up getting better performance

at the end of the day, this is an alpha which has suddenly become very popular so the servers are dealing with a lot at the moment performance can be erratic

You have no idea how much comfort those words brought me.

did u try gamebooster? is your GPU fan running at 100% speed?

[ErwinRumble 33]

Would like some more intelligent replies.

Would like some more intelligent replies.

ok, there's no need to be like that

riddle me this then... i have about half the spec you have and besides the odd spike, my performance has been fine.

what troubleshooting have you done so far?

suppose it also depends on what you consider as crumby?

That attidue won't get you far.

Anyways, turn off postprocessing, turn off vsync, or just accept that it is Alpha? I don't know, man.

You could check in Task Manager that all the cores on your CPU are used when you're in-game, I guess.. Sounds more like GPU though.

Because the game has issues by itself, please refrain from making such comments and accept the help you may get.

Make sure the core running the main game thread is not maxing out. AMD cpus stutter hard when any core goes over 98%. On my AMD 955 @ 3.9ghz will see 70% main thread and 10-30 on the other cores. Monitor gpu usage to see if its maxed out. Low settings tend to work the cpu harder - high setting tend to work the gpu harder. Higher resolution slows the whole show. Also, you need to have a fast hdd or ssd for good performance. Memory speed factors in as well.

ps: What are you expecting to get fps wise.

And remember that ARMA is CPU heavy, especially with alot of AI on the server.

It might be drivers, and it might be how you tweaked your settings. I am not kidding you, I haven't seen any pc yet, that can run ARMA II on highest settings smoothly. The reason is simple, while games like battlefield 3 and so forth can run smooth on high settings, it's due to the engine difference. ARMA has a much more demanding engine, especially on the cpu due to the sheer amount of calculations it has to do. First things first, for the best result, match resolution and 3d resolution to 100% (go advanced on the settings), turn off post prosess effects, it actually makes the game both uglier (fuzzy, it makes it harder to see actually) and slower.

ARMA doesn't have very good support for multi-threading either. I don't know AMD cpu's that well, but if it has an equvialent to Intels "multi-threading" in bios, turn that off as well.

And last of all, visit the Bohemia Interactive official forums for the game, there are a couple of threads there on how to get the most juice out of your PC in the ARMA II section I believe.

Lastly, your lack of performance has nothing to do with DayZ, it's just how ARMA is, it requires some tweeks, but once you learn how to tweek it for your rig, you don't forget. ARMAs adjustments are a bit strange too.

Good luck!

Misinterpreted. I mean more intelligent replies as in, keep them coming.

[blockhead (DayZ) 4]

what ping levels are the servers like that you're connecting to?

as far as crumby fps... what do you consider crumby?

Always below 100.

I consider it cummy fps when my aim is affected and or when things don't seem to be running smoothly.

[blockhead (DayZ) 4]

it's a hard one to judge given the server loads lately.

what fps high/lows have you been getting?

i suppose connectivity is also going to play a part. what up/down speeds are you getting and have you tested for packet loss?

Simply put' date=' ArmA 2 is hilariously poorly optimized.

First, despite possessing the LargeAddressAware flag on the executable, the OA executable (and the ArmA2 executable) cannot, under any circumstances, use any more than 2 gigs of memory. Whether you have four gigs or eight or 16 won't make a difference. It's two gigs max, period.

Second, at some point Bohemia Interactive decided that more people had bigger hard drive than lots of RAM, so instead of making the game RAM-intensive, they made it Hard Drive intensive. Watch your hard drive light next time to play. See it blinking like mad? You have no idea how much arma2oa loads and unloads from the HD.

Third, that also tends to mean there's a big chunk of page file/virtual memory it likes to use. Which increases hard drive usage even more. Fun!

Over all, the major performance limiter in the Real Virtuality engine is hard drive thrashing.

Lastly, Operation Arrowhead is a pure 32-bit executable. That means that regardless of anything else, Windows XP 32-bit remains [i']the best operating system to run it under. XP 64 is a little worse, and by the time you get to Vista/7, well, it sorta freaks out.

So, what can you do to improve your performance?

Your first option is to install a Solid State Drive. Putting my Arma2/OA installs on an SSD gave me a performance boost of anywhere from 10 (the horribly unoptimized frame-eater Elektrozavodsk) to 30 FPS. On average I see FPSs of about 30-60.

Your second option is to install such a stupid amount of RAM that the executable runs off a RAM disk. This is even faster than an SSD. Between ArmA2 and OA, you're looking at about 16.5 gigs just for the space taken up. If you're selecting and very tweaky and control freak about what you put on your ramdisk, you can ramp that back quite a bit.

As for operating it in a 32-bit mode, compatibility options will never be quite as good as a native 32-bit OS. However, if you put -winxp in the launch parameters of your DayZ shortcut, it does actually help quite a bit.

Lastly, I'd recommend turning Anti-Aliasing off. For some reason it seems to cause OA to freak out. If you really hate jaggies and really like anti-aliasing, I'd recommend using FXAA on the beta clients of the Operation Arrowhead executable, which even at its highest settings gives me much (much, much) better frame rates than FSAA on lowest settings.

Great post mojo, having similiar issues and will try the above.
