I'm gonna try that out.
I'm assuming that the process of extraction the atioglxx.dll file using dos is the same as using winzip.
So what I'll do is I'm gonna try using 5.2atioglxx.dll in the C:\windows\system32\ folder and 4.11 (or 4.3) atioglxx.dll in the Kotor2 folder.
Acleacius, what catalyst are you using (one for the driver and the one for atioglxx.dll). Also what is your ATi graphic card?
