Your display settings have nothing to do with how well VTK can perform.

What I meant was: Why are you moving your actor at such a high
frequency (1000 times per second)? To me it doesn't make sense to try
to move it that often (you're probably swamping VTK with render
requests).

I would try to move it maybe 60 times per second, or at least in that ballpark.

Where are these high frequency events coming from?

If you by any chance is using Qt 5.5, and these are mouse/touch
events, you could be suffering from QTBUG-40889 (fixed in 5.6).
