Checked on the drivers, my GeForce 320M seems to be updated as of now.

I'll try lowering the resolution, thanks. Wouldn't that mostly affect fps though? Doesn't seem like it would do anything for mouse lag. Do you know specifically what resolution command you're referring to?

I already tried USB Overdrive which can disable mouse acceleration, but I'll try this one instead. These are my current launch options, what else could I add to it?

-full -w 1280 -h 800 -console -novid -useforcedmparms -noforcemaccel -noforcemspdaccel -noforcemspd

As much as I'd like to, I can't atm. Long story.

Usually I play on windows, but over the winter break I have to play on my Macbook Pro (long story). It's frustrating to play on, since I get low fps and mouse lag. I can kinda deal with low fps to an extent, but mouse lag makes it nearly impossible to play.

I've disabled vsync and multicore rendering, along with mouse acceleration in OS X (since there's no raw input on macs), but it's still there. Is there anything else I can try? Is there anything I can do about fps as well?

This would also happen with viewmodel_fov 0, though I guess it would be doubtful that's the reason. It's worth a try to set viewmodel_fov 90 or something to see what happens, though.
