I believe I've found what's been causing problems in my games lately. While playing Battlefield: Vietnam, I noticed the screen flicker, strangely similar to the effect I had in FSO. I've not noticed that happen before then. So I wondered, what do BF:V and FSO have in common? HT&L! Out of curiosity, I entered the command line -nohtl in the FSO launcher and found that the problems were gone. No more warped textures, annoying flickering, and freezes.
I've already updated my nVIDIA drivers, but that seems to have made things worse. Does anyone have any ideas on how to fix this odd problem?
I have anti-aliasing and anisotrophic filtering turned off, BTW.
