Got a new 2010 MBP, and I've got my preferences set to always use the NVIDIA 330M chip, and never the integrated Intel one. Just got a copy of Counter Strike Source through Steam, all up to date, and running OS X 10.6.3. However, the game runs terribly, even on the lowest graphics settings. Less than 10 frames/second. Compare this to my old MBP with Mobility Radeon X1600, which ran the game maxed out butter smooth. Anybody else experiencing problems?
