I have been running pretty old 270.x drivers because the newer ones changed the behavior where vsync is enabled by default now (NOOOO).
I have a triple monitor setup at work and it syncs to my lowest refresh rate monitor which is only 48Hz which is horrible for the other two (67Hz and 60 Hz).
I have tried adding:
nvidia-settings --load-config-only
to my xinitrc and also in kdm’s kdmrc file I tried adding:
Additional environment variables KDM should pass on to all programs it runs.
LD_LIBRARY_PATH and XCURSOR_THEME are good candidates;
otherwise, it should not be necessary very often.
Default is “”
ExportList=__GL_SYNC_TO_VBLANK=0
I wonder if its not taking effect as maybe these things environment variables dont work until after X is loaded? That is a problem as XGL is openGL based and what everything runs under and is pretty much the main process which is running =(
Nothing seems to work. beryl bench is still showing 48 FPS which is driving me nuts. With steam for linux coming out I really want to use newer drivers now. Anyone have any ideas on getting around this? An option in /etc/X11/xorg.conf would have been nice for over-riding this
I guess back in the day I tested this and found that it seems like it only forced vsync with multiple graphics cards in use. When I did a single display/single graphics output it did not happen:
I have even verified the environment variables are being set but vsync is still being enabled. Using the old driver I get 200-300 FPS after the first boot and with the newer ones I am stuck at 48 FPS:
Its chicken and the egg. nvidia-settings needs X to be running already and does not effect programs already running. The problem is My X (XGL) is using openGL and already has vsync enabled before nvidia-settings can be ran). This really sucks =(
This issue appears to be specifically with multiple video cards. The environment variables work when I am only using a single video card. I recently upgraded to a two geforce 650 ti boost’s and now I have to run newer drivers and this is seriously screwing me. Is there anyway nvidia could add the old behavior back via an Xorg option or a module load option?
