valkin15: perusing some of these files on the site that OP mentioned, unfortunatly some of these mod .exe's contain viruses.
Avira was picking it up on the 227 patch for me.
I assumed it was a false negative and continued, but I was also experiencing some drop in frames and poor performance. Strange to see a game from the 90s drop to single digits. Doing a tiny bit of searching, dropping shadows seemed to fix a lot of users issues, not mine. Then I went and took a look at CPU affinity, that didn't work either. I wonder if it's a 227/opengl and AMD thing?
