setting refresh rate - Nvidia dual monitor and compiz

[ikiini]

I am having a problem. My refresh rate across my 2 22' screens is showing up at 50hz. the monitors can support 60hz.because of this compiz uses the 50hz. this cause some sluggish behavior that is really starting to annoy me. If anyone out there has a fix or suggestion to deal with this please post.

some info:

xrandr -q:

Screen 0: minimum 3360 x 1050, current 3360 x 1050, maximum 3360 x 1050
default connected 3360x1050+0+0 0mm x 0mm
3360x1050 50.0*

when look at the benchmark too on compiz it gives: 30 frames/sec.

thank you.
