Thread: ArmA2 / OA (low) performance issues

Also the in-built campaign is known as a performance-killer so it is rather optimistic to expect to run an 8K VD smoothly. Even a 5k VD at smooth framerates is tricky.
    -AA is set to Very High ( I'm playing at 1024 x 1280 resolution and I hate jaggines ), PP and World detail is set to normal ATOC is off and Memory is set to Default. Everything else is set to very high.

    -Correct me If I'm wrong but VD is mostly dependent on cpu right?

    You're right that VD is very dependant on your CPU's speed. Try decreasing Object Detail to High even Normal. Try also the noBlur mod, as well as CCleaner, defragging your HDD and Gamebooster.

    For defrag I have diskeeper 2011. I use gamebooster but I don't notice any diffrence since I don't have any stuttering in games ( in my old comp GB helped me by reducing stuttering )

    I'll order a new psu then and I'll overcloak my cpu to 4.6 ( I read 2600k can do even more ).

    I have a small question is this normal?

    I have a intel 4 gbites of ram (quad) I got it around 2008

    I play arma at everything set to very low except objects and textures to normal. If there is anything I can turn off in the video setting I already turned it off, and I am getting 14 fps on OA benchmark. No matter what I put in the lauch (-winxp -maxmem -cpucount=2 or 4) nothing improves.

    I thought you know what maybe that what my comp can handle but before I called quits I checked my cpu usage during the benchmark.

    My cpu usage was capped at 30-40% (cpucount=4) Why? Why cant it be 80 or 90 why only 40% It never surpassed 50%

    If you can give any tips i would really apreciate it or of my computer is too old just let me know

    Thanks in advance

    (before you go about telling me to overclock and change hardware just want to let you know Im not good with computers, I didn't know what overclocking meant untill yesterday )

    Arma2/OA has been dual core optimized not quad core optimized.
    This basically means that when running on a quad core it'll use all four cores but to limited amounts. This has been an issue I've had since release and would be why everyone suggest over clocking as a solution.
    A faster dual core cpu will out perform a quad core 90% of the time with dual core optimized games thus pure brute force ghz will win the race.
    What I would suggest is if you cannot overclock lower the settings until you can get a solid 30FPS then get DXTORY (google it) and cap your fps on arma2/oa to 30.
    This was the only way I could get a playable frame rate even with my rig. And also I disagree with what the developers/other players say about Arma2/oa being playable at 15FPS or greater.
    30FPS will always be an absolute minimum and I rarely settle for anything other than 60FPS as smoothness is a major factor in accuracy especially in close quarters battles.

    Hope this sheds some light on the situation and provides some help in some form.

    The thing about SP versus MP performance in this game is that in SP you have a TON more scripts and AI running around than in MP (usually). If you play the campaign in co-op you will see that performance is typically just as bad as the same mission in SP.

    View Distance definitely has the most affect on framerate, and because it and AI/Script performance are so CPU-bound, you are able to increase it very far in MP where not much AI is running, but in SP it will slow to a crawl.

    Terrain Detail is probably the second-most largest hit on framerate as well, which I think also couples with VD in that it seems to relate to grass detail at distance.

    A good computer not being able to play Arma OA well.

    I recently bought Arma OA and I found out that I have a hard time running it. I have 8 gigabytes of ram and a quad2core cpu running at 2.4ghz. My video card is a gtx 570 2g. I can run games like crysis and bf3 on ultra settings at a 1920x1200 resolution fine at 60 fps. When I try to run arma I barely get 30. Whether on ultra settings or lowest possible I get the same fps. I have disabled vertical sync and all my drivers are updated.

    unfortunatly, a core²quad at 2.4 is quite underpowered for this simulation. you can't compare bohemia product to any action fps game.
    but if you have opportunity to overclock it , it can do the job. my Q6600 (stock@2.4Ghz) , the same than you , ran for 2 years and half at 3.2ghz . you need a BIG cpu cooler for this old mule

    Really? I did not think that was the problem. When I go to the task manager and check the performance, only 25 percent of the CPU is being used and 50 percent of the ram. Maybe Arma 2 isn't utilizing all the cores properly?

    That is pretty much how Arma2 uses the cpu cores. Nothing we can do about it basically except to accept it. OC the cpu and u might get few extra frames.
