turn off z buffering and DXT formates, Tripple buffering. run at X2 AA and AF. Catylist AI make sure is set at Standard it take big hits on FPS when enabled.

i did that, and performance increase thanks, but the performance is the same with a single graphic card , otherwise, i tink performance will be better with crossfire. Do you know if il2 is incopatible with crossfire?

eable crossfire then check on DXT and turn on check on for tripple buffering do not turn on Zbit buffering that will greatly reduce your FPS

make sure to check and see if standard for Catylist is still standard sometimes windows Vista moves it for itself best performance setings.

I do know that X2900 are not that great I have 2 3650s and the game runs at 60 FPS on average.

Im leaning more towards NVIDA now that I see they are out performing Open GL with ATI.

Hi, i already had done this
Look this, is estrange that the second graphics card show named in the CCC as "Disabled Adapter".

this game is not optimized for SLI or Crossfire

thanks, good to know that ^^

GF_Mastif, have you apreciate a better performance in il2 whit crossfire?

ok I see that it states Disabled adapter; thats not what it should say. It should say linked adapter so you have a problem with your set up check to make sure its seated correctly in the mother board.

Also if thats not working, change card sides switch them around.

I think you may need a link bridge for that card too, not sure?


also place them in singel and see if there working individualy

And get the latest drivers for both OS's 8.11
