Sorry Wolfgang,
there is really no need to even start the old "pc vs console" thing that is going on in the steam forums as well.
Please... I could also have it running on PC or MAC but i just want to sit back on my couch in the evening for a few hours fun without the whole win/mac os update/graphic card etc. etc. thing... (just my 2 cents)
Thats why we try to find out what could possibly be wrong regarding the lags on the xbox version...
If we find something, fine. if not, we wait for the update...
Cool?
