[win7] Bad quality when not on primary monitor or window has no focus

Yes no doubt about that. When I disable vsync, framerate rises to about 90 FPS. And it does its job perfectly, as long as the 2 "requirements" are met.

Can you make sure power management is not enabled in the nVidia 3D settings. The setting should be called "Power management mode" and you will want to make sure it is set to "Maximum performance".

Also, this is not ideal, but try enabling the 'viz.glFinish' option:

viz.setOption('viz.glFinish',1)

Why is this not ideal? It didn't seem to have any effect. But I guess it could have some benefits in certain conditions? (and some negative side effects?)

Let me know if any of these make a difference.

I tried both (also combined), but unfortunately none of it appeared to increase quality and the problems still remained.

The glFinish option is not ideal because it blocks at the end of the frame for the GPU to finish rendering. This can reduce the framerate in some cases because you lose the parallelization of the CPU and GPU.

If you disable vsync, what is the reported frame rate in Vizard? If you are getting tearing with vsync on, then this is most likely a driver issue. Do you have the latest drivers for your graphics card installed?

Without vsync, the framerate goes somewhere from 70 to 100 or even higher, depending on which scene is loaded or which part we're in.

I have the latest (stable) drivers, downloaded from the nvidia website.
