Quad Buffer

[Gladsomebeast]

When you first run scripts with viz.go(viz.QUAD_BUFFER) does it print "Visual Choser: cannot apply settings" or something like that.

The error I get is:

Producer::VisualChooser: the requested visual is not available, try relaxing attributes

It gives that error 3 times in a row.

Yeah, this sounds like a nVida driver/settings fix. Assuming you have installed the nVida Quadro drivers, check the nVida control pannel for a quad buffering setting.
