[Mesa3d-users] frame rate

[Arnfried G. <arn...@gm...>]

Hi,

I've written a simple routine to get the frame rate of the monitor. The
program is very simple, it uses a loop for calculating the time of 100
glXSwapBuffers(). On my SGI with OpenGL it works fine, but with MesaGL
it failed, because the swapping of the two buffers is not syncronized
with the vertical monitor sync.

My question is if anyone knows why glXSwapBuffers() doesn't wait for a
vertical sync or if this behavior is correct.
