Hello Raze thanks for answer.
Steam has detected one defect file. Unfortunately, the repair has no influence to load speed.
My Hardware: Core2, 2GB RAM, NVIDIA Geforce 8800GTS, HDD for Windows/games.
This is lesser than the hardware recommendation and probably the cause.
But I don't understand why I have only problems if I loading a stored Level (or switching Level). The play performance is ok.
