the Tearing Test was like running on 24fps (but the svp icon says it on 60fps)
when Stereo Mode (3D) was ON.
It is bad. You need to find the cause of this. What player do you use?
what Stereo-frames Order should i use?
For active 3D-glasses (shutter glasses) usualy greate works "left then right". In some case you need "right then left".
For passive 3d-glasses (with polarized lenses) you need "simultaneously".
In any case you can run Tearing Test and try them all. Tearing test line must move smoothly and without double contours when you view without 3D-glasses.
are these settings more CPU intensive than 2D mode?
Yes. "left then right" and "right then left" are more CPU intensive.
