You really reaaaaaaaaally sure? "
I tried putting the atioglxx.dll in the SWKOTOR2 directory, the result? an error message saying something about the file not being a valid windows-memory-thingie (I'm running a swedish edition of XP so it's kinda hard to translate the obscure errors you get from windows). Same thing happened with SWKOTOR.
If it's not too bothersome, would you mind giving a http-link for the exact catalyst-driver you're using? or just the atioglxx.dll-file itself?
