seems like we have...as soon as i select a4all in Cross, latency just goes nuts...

Edit: I'll try reinstalling the MB drivers now
2nd Edit: Nothing changed. Look, i don't know what's going on with my system, it just gets slower and slower every time i reboot. It just makes me very angry if everything is refusing to work....and what i do in such situations is reinstalling the whole OS.
I got an appointment now and when i'm back i will re-install Windows, reset BIOS and see if it works after that.
Greetings and thanks for your efforts,
Markus
