Re: Wine + VSync forced in nvidia-settings doesn't work
Thanks for the detailed analysis. Bug 839481 is filed to track the fact that __GL_SYNC_TO_VBLANK does not, despite what the README says, override the programmatic swap interval control specified by applications.
lexa2, I don't think the GLX_SGI_swap_control spec states that you can't disable vsync once it's been enabled. The "minimum" it refers to is the minimum number of video frame periods before the next buffer swap, not the minimum value you can ever set the swap interval to.
