Hello all. I have a Rage mobility and am using the latest dri drivers and kernel (just upgraded to 2.6.10-rc1-mm2 today) and a lot of the OpenGL applications I run are very much slower than on Windows. Specifically, I'm referring to NVidia's TreeMark demo and Soldier of Fortune for Linux.

I'm pretty sure the reason is because the programs are using OpenGL extensions that the hardware does not support. I think ARB_multitexture is the primary culprit since I'm pretty sure that mach64 chipset doesn't support it (correct me if I'm wrong). So is there a way to turn off those extensions at the driver level (or at the application level for TreeMark)? If it means having to compile the dri OpenGL driver, could someone tell me where to get the sources?

Thanks for any help
