Using my ATI Catalyst Control Center, I set my 3D Refresh Rate Override to Same as Desktop. This was the setting that seemed the closest to what you described. Yet, I still get the same results as before: anywhere from 100 to 400 fps, depending on what's going on on the screen, and what my PC is doing in the background. I also tried changing it to a few different settings, such as 60 Hz, 66 Hz, and 70 Hz. None of them seemed to make any difference.

with my new graphics card I can get frame-rates above my monitor refresh rate and so I tested vsync=on in Nvidia driver panel.
In windowed celestia I get 85 fps (my monitor default refresh rate)
and in full-screen I get only 60 fps ( monitor switches refresh down)

I found lots of old threads about the problem but has it been solved ?

BTW: Have CPU-load below 50% for the first time
