Battlefield 2142 seems to be running very slowly on my 17" macbook pro 2.33 with the x1600 256mb card. I've set all settings to lowest, but the game still runs choppy. Same on my imac 2.4 with the 2600. Why would this be? Both of these exceed system requirements. The poor gameplay has ruined my BF2142 record as whenever I approach to take out anyone it runs fine until I get close and start shooting, then fps drops to like 2 and I end up shooting wildly in the air at nothing. K/D ratio has gone from 1.3 to .7
