your graphics card should have an option. It probably isnt vsync its gonna be anti-aliasing and anti-f (cant remember what its called).

turn all of them off including vsync and no more fps lag

Not at my linux box right now, so I'm not 100% certain... but try

nvidia-settings

(or nvidia-configure, or something like that

) that is if you're using an nvidia card, if not, I don't have a clue.

The setting you'd want to change is "sync to vblanc" for opengl, I'd say that this is by default off. I use sync to vblanc because I feel my aq2 performance in linux got lots better with it on.

Oh, and you need to set this every time you reboot (there was a switch that you can use to just load your settings and add that to your startup script... try nvidia-settings --help...)

Hope that makes some sense

with all that shit on, in a gun fight my aq2 drops to like 30 fps.

vsync (or sync to vblanc) just means that the FPS will be synced with the refreshrate of the monitor... so if you're using a reasonably fast refresh rate on your monitor, the only thing you should notice when turning it ON is that it will be smoother... lots smoother... I myself use 102Hz @ 1152x768 in linux, so I can't say my FPS are too bad (also 102)

AA and other image enhancing options will decrease your FPS to produce a better quality image. Don't confuse the concepts here, because VSYNC and AA doesn't have anything in common
