Disable VSync in 13.04?
Hey guys,
How have you been disabling vsync in Ubuntu 13.04 with the R600g driver? I have a R770 (4870), and I have set up a custom xorg.conf and disabled sync to vblank on compiz, and I've disabled it in-game, but the FPS will not exceed 60 FPS.
Any ideas?

Could we possibly get some benchmarks on L4D2? Either on different AMD cards, or a comparison with Windows, or Catalyst/FOSS.All opinions are my own not those of my employer if you know who they are.

Honestly if his monitor is higher than 1080p and he's pushing it using a 4850 at settings higher than low (which he implied he was) i would immediately assume the performance would be bad whether it was on Windows or Linux.

On Windows (7+8) I was able to run it at 1080p with all the graphical settings cranked up to max (though possibly not antialiasing - it's been a few months and I can't remember) and getting very good framerates.
