ArmA2 / OA (low) performance issues

[Leon86]

some ati drivers seem to work better than others, if you find one that sortof works stick with it is probably the best advice.

If you look around the internet you will see there are mixed results with both sli or crossfire. Its almost random luck or random bad luck, either way..

Well if anyone here can recommend an ATI version that works with crossfire, I'm all ears. 12.6 / 12.7 do nothing at all for me.

I'd like to know which one works best for a single 6950. I'm currently using 12.6 but if others have used various and found another one to be much better then please share.

That's just an idiot who put everything on max and is cpu limited. sli works fine in arma 2.

Just pointing out that when saying for certain something on here, its really your own opinion.
Another idiot for you, I can put 100's of these idiots up on here, but its not worth it, as I doubt they are all idiots. Sometimes sli works fine, sometimes crossfire works fine, but by just looking around on the internet you can find people having problems with both for arma 2, plus of course I can find lots of people loving using them, its just simple research to see if your machine will likely run well with it.. To take one persons word for it is not really that sensible, especially when it costs money..

[Leon86]

It's just unfair to sli to say all dualgpu setups suffer in arma 2, many have tried both, sli support for arma 2 is much better than crossfire support.

sometimes pumping LOD scaling into locked-down state to prevent LOD flickering/shuffle issues/impact was smartest thing you can do, especially if you fly alot online.
about CFx impact -try fiddle with re-naming game binaries - various appz CFX profiles triggered on by different ones.
forgot name of program, that allow to manually edit CrossFire profiles and fine-tune them.

Every pc bogs down a bit in cities, it's very heavy on the cpu.

arma only scales well to 3 cores and beyond 4 there's no real gain anymore. Your cpu has quit bad "per core" performance.

you could increase performance by using lower model detail or very low viewdistances, or overclocking your cpu.
