Hollywood props...?

[adonys]

I think it's an effect scalable with the PC's performance, ie FPS..

On my computer, the propeller effect is the same as I understood (the bold is for the guys accusing people who asked for a slowly rotating propeller arc, as in the movies, that they requested this new effect, when in fact after the looong discussion we had about this, I think everyone understood that is it not how it is seen in real life by direct observation) that it should be from people who experienced it by themselves: visible variable rotation speed blades on very low RPM, and a translucent (almost invisible arc) with flashes of blades lights now and then (depending on the eye/sun position). Which is exactly what am I seeing on my computer.

If you're seeing something else, it must be either the FPS, or drivers (or amd/ati vs nvidia videocards maybe)..
