I can play the game for about 5-10 minutes, then it freezes. Sound too.
Have tried any possible fix from these and Obsidians Forums: From disabling sound, through disable vertex bufffers to the wnaspi32 thing. Also I tried to install every possible driver from 66.93 to the 67.66 (only Beta downloadable). Didn't work.
Older drivers don't recognize the Geforce 6600 GT.
My specs:
AMD 2600+ XP
Windows XP Home Edition
Winfast A6600 GT
512 MB RAM
An interesting thing is though, that I tried 3 days ago to start-up KOTOR 1 again and have got the exactly same problem. A year ago as I had the exact same computer configuration without the Winfast Graphics Card but with a Gainward Geforce 5600 FX, it worked perfectly.
So I presume the crashing issue has to do either with the newer drivers or with a problem in the newer graphics card architecture.
So...there's no way out...simply wait for the urgent patch...
