Joe was kind enough to send me the files so I could have a better look. With a GeForce 6800GT & an AMD XP3200+ (quite old by todays standards) my framerates never dropped below 115 during testing. Some neat ideas you guys are playing with in both sections of your duel test!
EDIT: I realize a lot of players here have computers even older than my 4 year old rig. I'm just saying we shouldn't hold back new ideas just because an 8 year old pc gets low fps. Just my 2 cents.
