>From the nvidia README (Linux): VBLANK SYNCING
Setting the environment variable __GL_SYNC_TO_VBLANK to a non-zero value will force glXSwapBuffers to sync to your monitor's vertical refresh rate (perform a swap only during the vertical blanking period) on GeForce or newer hardware (ie: everything but TNT/TNT2 products). For windows people, there is probably something similar in the windows display properties. Enabling this feature caps your frame rate at your monitors vertical refresh rate. Assuming FlightGear otherwise would have run faster, this locks FlightGear into a stable fixed display rate that is synced perfectly with your monitor. As long as you don't drop frames, you end up with *silky* smooth motion. ***Very nice*** definitely try this if you haven't already. I'm sure other video cards/drivers have something similar if you dig in the docs.
