If you export __GL_SYNC_TO_VBLANK=1 in your environment then that should force the nvidia driver to sync to vblank.


Apparently I had tried messing with some other environment variables earlier, but this one didn't do it either. It shouldn't be this hard to tell a GPU to slow down when it draws things.


That was one of the things I tried and somehow it still didn't do it. Setting it in the individual games' settings didn't to it either. I'll try one more time though.


I assume the PPA you added was xorg-edgers? I needed to use that one to get my nvidia card working (was quite a new model when I got it...)
