I "solved" the problem with the fps - it wasn't a real problem, I just got confused because of the two runs. The first one always has the same speed, but the second one has the intended speed. That's allright.
What's left - how can I get rid of that annoying first run? (The workaround provided in your link is not helpful because in that case it is not possible to change the fps.)
