WTF?!? The nVidiaVideoSync method was written to work with those nVidia
drivers, wasn't it?
nVidia broke this some time after the 4xxx series of drivers. The new
ones (6111 and later) work well with OpenGL vsync. Be advised that some
(myself included) have trouble with the latest driver and MX440/MX4000
cards and need to drop back to 6111. You should be happier with this
card and OpenGL vsync.
So, I finally got around to trying this. I'm using kernel 2.6.10 which is tricky to get going with the NVidia drivers. I managed to get nVidia driver version 6629 installed with some minor patches. When I start it up I get this:
> 2005-01-16 17:17:10 OpenGLVideoSync: GLX Video Sync extension not present.
despite `glxinfo` returning:
server glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control
client glx vendor string: NVIDIA Corporation
client glx version string: 1.3
client glx extensions:
GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_EXT_visual_info,
GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_SGI_video_sync,
GLX_NV_swap_group, GLX_NV_video_out, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer,
GLX_SGI_swap_control, GLX_NV_float_buffer
GLX extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
GLX_ARB_get_proc_address
Which appears to include GLX_SGI_video_sync. I assume this is what you were talking about when you mentioned you "had trouble" with the latest driver?
I also turned XvMC on at the same time. This seems to help the tearing problems somewhat, but I'm going to try the 6111 drivers and see if I can get that to work.
Be well,
Will :-}
