OK, got it loaded on the Athlon 2x 6000+, I did download a new steam account,etc. all is well. Campaign is slightly laggy- playign on a 19 inch older monitor at 600x 800, 4x anti, etc. but honestly I cant tell as the game itself seems so much less smooth than BC2 or even 2142. I hate the slow motion crap to fast motion as you break in a door, etc. However, actual shooting/killing enemy seems easier than BC2. I did not have time to try multi-player yet- plus the fact the controls are slightly different and I wont know the maps at all, so I will get "owed" badly. I will try Multi -tonight- maybe- depend on how frustrated I want to get-LOL.
