I get CTD in OA every time I play. It's different how quickly it happens. It happens both in the campaign and in training. I installed the Win 7 GPU stress MS hotfix posted on this forum in a sticky. No difference. Old Arma 2 and other games runs good with no CTD. When it crashes it says OA has stopped working.
I'm running with no mods (ACE 1.2 is installed though.).
Here's my target line:
"D:\Games\ArmA 2\arma2OA.exe" -nosplash -cpuCount=4 -exThreads=7
Things I will try:
-sound is set to 128 in OA. I'll try decrease that.
i7 930 @ 4.2
6 GB ram
5870 with Catalyst 10.6, Cat. AI set to advanced
Xonar Essence ST
Win 7 x64
Another bug: In options it seems that object and terrain quality reverts to normal each time game starts.
OA is awesome otherwise! If I don't sort out the CTD I sure hope BIS finds a fix.
