yea. I noticed the frame rate was tuff to get with full detail. I used to have a method to determine how good my upgrades affected my frame rate in AH1. I would go to the baltic terrain, line up a formation of b17's on a runway (I forgot which one), move to exterior veiw, zoom out all the way and pan up at a 45Degree angle directly on thier 6 and check the frame rate.
In AH1 I managed 23 frames per second with my 1.7gig p4 pc133 rig.
Now, I have a 2.6p4 clocked at 2.9gHz. ATI 9800 pro, pc3500 mushkinRAM (1 gig) and was astounded to get 23 FPS in AH2! Wow, I tgought.
