It's not hooked up for Linux, since XFree can't switch color depths on 
the fly. Some X servers can (although I don't know if any X server for 
Linux can), but I'm not willing to hook it up and field a million bug 
reports from XFree users. Restart X in 16-bit mode if you want to try.

For Direct3D on Windows, you can switch color depths from your desktop's 
default if you are running fullscreen. On Linux, we just use whatever 
color depth your X server is running at, period.

It's in the README that comes with Nvidia's GLX implementation.

export __GL_SYNC_TO_VBLANK=1

(I think)
