Ever since I upgraded my kernel to 2.6.7 from 2.4.26, I've noticed a slowdown in openGL rendering. Games run slower and are at times choppy. I had a hell of a time gettting my NVIDIA drivers installed, (rivafb module problem) but after I did, all GL was a bit slower. I also don't have sound in games any more but that is another thread. Has anyone else noticed problems with openGL and 2.6.x kernels, and If so how did you fix them?

Slackware 10
xorg 6.7.0
NVIDIA driver 6111
cedega 4.1-1
alsa-driver 1.0.5a

I havn't had any problems with the 2.6 kernels as of yet. I am thinking possibly that the system may not be using the agp. Use Option "NvAGP" "3" after the "nvidia" line to make sure the agp is enabled. the "3" will use the kernel agp if it is there and if it isn't will default to the nvidia's agp driver.
From my experience with games and such when I went to the 2.6 kernels my frame rate stayed about the same but my mouse became hella fast. I had to turn down most of the sensitivity settings to make my games playable for me again.

This is just a guess obviously but it's the only real thing I can think of atm.

GL

I must have formatted the line wrong because your suggestion crashed x. I had it written like this:

Maybe that is not what you meant but It is no matter. My problem turned out to be with my cedega/winex config file. I never changed the file after my upgrade, and for some reason It worked fine in 2.4 but not 2.6.

The offending lines refered to my video ram:

this not this and the sound driver section

this not this Thanks anyway though
