ArmA2 / OA (low) performance issues

Using 3 cores didn't help at all.

Using 3 cores didn't help at all.

You have a phenom II x6, it has 6 identical cores, using -cpucount=3 might benefit the FX cpu's because they're made in pairs of 2 cores that share a great deal of hardware. with your cpu there's no reason it should help, more likely the opposite.

overclocking might help, but you'll need to make sure your motherboard can handle it, you have to have an aftermarket cooler for the cpu and it's quite time consuming if you do it right.

Hey all,
Whenever I change the settings in game from Low to Very High, my FPS remains in the same 34-40 region, sometimes dips in the 20s but the change in graphic quality is minimal. So, I'm assuming that my FPS issue is processor related. Currently I'm using an AMD Phenom 955BE (3.2Ghz x4) and have no FPS issues with other games. Are there any small fixes or specific options that could be disabled to improve this?

Thanks

It depends on the settings. Model detail and viewdistance are real cpu killers. antialiasing is heavy on the gpu. Shadows on high/very high is gpu only, on medium/low it's cpu.

Slevich: good advice (as always) from Leon86. You can find his advice and more in this thread:

I am having trouble in ARMA II: CO, when I play the game it runs on about 30-45 FPS, changing settings does little to no change (1-3 fps).

Specs:
i7 950 @ 4.2GHz OC
Dual 670 in SLi @ 1.2GHz OC
6GB RAM @ 1600MHz
1200W PSU

Tried fixes:
Adding -winxp
Beta patches
Different drivers

EDIT:

I disabled Hyper Threading in BIOS, now I get around 180 fps on the menu screen rather than 50. But when I join a server (DayZ) I get back to 30-45.

Have u tried different servers? Afaik, DayZ has some FPS issues atm. Also try at the Editor to see how the game runs in different parts of Chernarus.

Ok... I'm still getting really bad performance with my PC in ARMA 2 Reinforcements , but according to benchmarks, it should be running fine with EVERYTHING maxed.

Specs are as follows:

i5 2500k @ 3.3ghz
ATI Radeon 5870 x2 Crossfire @ stock speed
16GB DDR3 Patriot Gamer Series 1600mhz RAM
Gigabyte ga-z68x-ud3h-b3 motherboard
250GB+160GB OEM Hitachi + Samsung 7200rpm HDD
1050W OEM HP Power Supply
Windows 7 Ultimate


I'm hardly getting 15 even with two 5870's.


I get like 40+ fps in ARMA 2 regular, but why is it tanking in Reinforcements?
What is wrong? Thanks


EDIT: OK I found out why... the higher precision HDR the worse the performance and the worse (blurrier) it looks. 32 = 15-20 fps, 16 = 25-30 fps, 8 = 40+.

@ruhtrael: what is wrong is your statement "it should be running fine with EVERYTHING maxed". Where on earth did you read/hear that?
Practically no machine on earth can run OA with EVERYTHING maxed.
You have to realise that OA is an extremely sophisticated game, WAY more complex that the majority of games out there.
You have a pretty fast machine there so with a few tweaks you should be able to increase your framerate while keeping the game looking good.
So try these proven optimisations:

And let us know how you get on

Trying out settings one by one is the way to go to make arma run and look good. The developers allow some crazy settings that will cripple performance on any rig if you max all of them.

Performance is very dependant on map and location as well. On the small island map utes you can proably max viewdistance without problems because there's only extra sea to render (no extra work for the cpu).

It runs everything maxed fine now. I just had to change HDRprecision to 8, now I can jack up all in game settings to max and still always get 30+.

Just a quick question. Is it normal for my spec below to run OA at less than 20fps with most settings the highest(AA low, postprocess low, Visibility 6400, V-Sync disabled, 1920x1080)

i7 2600 (not overclocked)
4Gx2 DDR3 1600Mhz ram
GTX 590
Asus P8P67 Pro
Intel 510 120G SSD
Windows 7 Ultimate x64

Which of the settings are the most demanding?

Thanks.
