Hi,
Are you using vertex programs in your port?  What hardware are you
using?  Is it an R200 based chipset (Radeon 8500-9200)?  If so, I
recall seeing similar issues with a couple of games I beta tested.
The problem had to do with the R200 drivers and vertex programs.  I'm
not sure how the developers solved them.

I just glanced in the archives and Nicholas Francis noted a cause in
his app (fog and vertex programs).  This was in May 18, 2004 "Re: ARB
vartex program crashbug"


Thanks for the info

I have narrowed the problem down to the shaders. I am still digging
into the code to see exactly what path through opengl that code is
taking.

Yeah, KOTOR was one of those games. As I recall, the specific issue was that one of the vertex shaders was outputting a fog coordinate while GL fog was disabled, yet a fragment program needed the output. I seem to recall that I ended up modifying the vertex program to output the data to some other register instead and modified the fragment program to look for it in the new place.
