 Can you try completely removing the "GLX_TEXTURE_TARGET_EXT, tfp_target," 
line from the attributes and check if that helps? It actually does not seem 
to be necessary here with either of the machine I have now at home, I'll need 
to check at work again what the problem was.

 I also remember that after the npot patch the machine at work (GeForce FX 
5500 IIRC) took noticeable time in bindTexture() in non-TFP modes, but here 
both GeForce2 MX 400 and GeForce4 4200 Go don't have this problem either (all 
using 9631 driver). Can you see it on your machine? Maybe there's something 
fishy with the work machine.
