I've just recently installed IJET on my new computer with a new video card, an NVIDIA GeforceFX 5900SE card from eVGA. And to my dismay, I found the all of the metallic textures were tie-dye, rainbow colors. The belt buckles, the pistol, the shotgun, Mei ying's glasses, many many artifacts. Also, the objects in the game: leaves, trees, chairs, tables, chains, almost anything, would occasionally be highlighted blue or green when looked at from a certain angle. How do I fix this problem? I've tried turning the resolution down and up, color bit 16-32, all those hightech video card controls (antialiasing, antitrospic something, midmap emulations?, etc) on and off, it's still there. I've updated the video card drivers with the latest version (56.56).

Have you already installed the update 1.01 for IJET? This fixes several video card problems!

I cannot help you. There seems to be video problem for new NVIDIA and some new ATI cards.
