Disabling sound entirely doesn't fix the stuttering, so I see no reason to believe this is sound related.
How did you diabled the sound ? There are great chances that even with no sound (volume off / mute) the sounds are loaded into memory and even played by the computer.
You can start the game with the '-nosound' command line option to disable the sound system completely. That aside, I don't get these stutters with GLSL off, so it seems a much more likely culprit.
Are you using nvidia binary drivers, by chance?
