I have this awful issue when running dual monitors with this set up. I get the worst kind of performance/lag, and im not sure what the problem is. When I disable either of the monitors in the display settings, I get exceptionally fast performance so it's either something with the GPU drivers, or the computer itself not being able to handle it?

Specs:
8 gigs of ram
3.4 ghz Quad Core cpu

The monitors:
1440x900 19" LCD monitor @75hz
1680x1050 LCD monitor @60hz

Could the issue be related to both monitors being a different refresh rate? I didn't see a place where i could change the refresh rate in ubuntu.

I'm currently using the open source tested drivers. When I used the proprietary ones, it wouldn't let me set up two monitors outside of mirror mode.
