brian,
as guillaume pointed out in an earlier posting in this thread there seems to
be a problem though. i've tested 3.1 on rh9, nvidia 1.0-5336 and see image
tearing. i've rechecked against 3.0.2 (same system, same nvidia driver) and
no image tearing occurs.
also, i'd like to point out that the nvidia driver supports GLX_SGI_video_sync
but pf3.1 still says "No vsync GLX extension. Emulating vsync.". what's the
deal with that?
j.
