After building gputest I run 'gputest_gui.py'.

Here some tests don't run at all.

However, at 1920x1080 'Julia FP32' runs nearly fluently, with a little
bit of stutter, but 'Voloplosion' is completely stuttering, no flow at
all and even the mouse cursor is sluggish. IOW a short 'freeze'
(stuttering) not necessarily indicates a broken GPU. My GPU is probably
just not powerful.
