Hi !
for the GL_CLAMP_TO_EDGE problem, i had the same some days ago for my skybox, but now i use GL_CLAMP cause it works very well (witgh a Geforce 2). so i don’t think you really need GL_CLAMP_TO_EDGE. :-/
i can’t play the game… i can move the camera, rotate it, but I can use the keys N, ESC, Q and SPACE…
the game is very smooth anyway…
