Sync to vblank still not working since 177 series

[thibm]

Hi,

My system is ubuntu 8.10, x86_64, 2.6.27.10, no compiz.


With 173.14.15 driver sync to vblank (set in nvidia-settings : xvideo +
opengl) is working as expected in opengl apps (59.9 fps in glxgears and
particulary in quake3-based games --ioquake3, enemyterritory). Since
177.8 and also in the last beta 180.18, sync to vblank works in glxgears
but not in quake3-based games, regardless of the value of the checkbox
in nvidia-settings.

Also running racer for windows with wine is fluid and vblank-synced with
173.14.15 but with 180.18 it seems vblank-synced. The problem is that
with 180.18 the framerate is set above 60fps for short times (just
visible - a sort of lag in the game) and then go back to 59.9. With
173.14.15 the framerate is always strictly below 60fps.


Cordially,

Thibault
