Also, when using OpenGL painter, the nvidia-settings OpenGL (not video)
Sync to Vblank setting may have an effect. Unfortunately, in testing,
it seems that the effect it has differs depending on system
configuration and/or driver version and/or ... (Meaning some may need
it on and others may need it off.) As a matter of fact, I'm relatively
certain that it is what's causing the 100% CPU load issue for some.
