why would this slow the game down horrendously though? :(

Has this been common?

I did try putting my MP code into steam and it didn't recognise it. I didn't try Mp yet and get gamespy account.

however I did apply the rather 3 large patches unbeknownst to me, and it seems to be much smoother now...! ive played the same area which I had the problem and it hasn't done it in an hours playtime.

So think were okay now..

thanks guys for the assistance much appreciated.....:)
