you need to look at the statistics HUD and note down the graphics percentage and movie percentage.

which graphics card are you using?
what os do you have installed?
what compression where you using with your files?

what resolution was your output screens?
what projection devices where you connected to?
and running at what refresh rate?

something does not appear to be setup correctly ?



the 'speed' setting affects a very low level graphics settings, that is way below anything i can do anything about.
