Help with HD 5750 3D accel?

[Felix Blanke]

I have the same card and use some other git versions, like mesa etc.


But I can't tell you the fps rate from glxgears, because I have vertical sync enabled
(seems to be default?!) and I have no idea how to disable it.

So I'm getting 60fps all the time :)


Regards,
Felix
