[Mesa3d-dev] GLX_SGI_video_sync on i945

[Ulrich v. Z. <ulr...@ar...>]

Hello,

I've been trying to get handling of vertical blank waits working on an
i945 (Mesa 6.5.1 using the i810 driver) without success. Specifically,
WaitVideoSyncSGI causes waits that are much too long when used to wait
for more than one vblank (i.e. WaitVideoSyncSGI(2, 0, &count) results in
about 3 frames a second). Waiting for one vblank works. The same code
works on old matrox r200 cards.

Is this supported?

Regards,

  Uli
