Crash happens during the "PrecacheDraw" call, but not the first time BeginDraw is called.

Unshadowed RM and no custom shaders in use.

Test level showing crash

[xordan]

I've got a similar (or identical) divide by zero error in the water level.

For me it happens inside cgCompileProgram however (glshader_cgcommon.cpp:721).

[xordan]

I just had this in the castle level also. It only happened after a couple of laps of the level though, not right away like in the water level.

NVidia made a new build with bug fixes available for Cg, one that is newer than the one in cs-win32libs: http://developer.download.nvidia.com/cg/Cg_2.0/cg-redist-2.0.0016.zip - Using the DLLs from that package make a difference?
