You say you use quad core why not use "cl_threaded_bone_setup 1" easily a 5+% boost. their's also a couple other things I noticed from the screenshots, but I don't know the exact commands.
If you look at process you'll see that ribbon, I can't remember the commands but that can be 2-3% extra frames for disabling.
-edit-
mat_specular 0 // Controls specularity. Setting this to 0 will make ubers
// non-shiny, and will remove some specular effects from in-game
// entities which support it. Setting this to 1 on dx8 will
// result in some strange `fire' textures replacing their
// appropriate counterparts, especially on medals, and certain
// hats.
mat_trilinear 0
I also disagree with how this is setup, so far I've found having mat_specular 1 has better framerate when trilinear is off, but I wouldn't be surprised if you've found something different.

r_pixelfog 0
I'd highly recommend this for DX9 users it doesn't improve FPS much but it makes everything SO MUCH clearer.
