The demo on the video was actually taken from a windowed game. (fraps only recorded the window)

I only use fps_max=60; and everything with a time factor.
no timesmooth.

In theory, the movement can only be fluent, if there is no timesmooth,
as this is exactly the timeshift between two frames.

But i think there is a problem when the framerate drops below 16FPS.

Since i have a pretty fast computer now, and alway write the code as fast as possibele, I dont
run into major problems.
Its another thing with slower computers. But on my laptop, the game runs quite smooth too, even when
it is already 5 years old.

I am also very reluctant to shaders/effects, especially if they do not improve the feeling of the game.

The only shader I use is the multi-terraintexture-shader from the templates. (about the only think I find useful for me
from the template source)
