View Full Version : Radeon HD 4870 Iffy Performance

Sep 14, 2012, 01:07 PM
I have 2006 Mac Pro with a Radeon HD 4870, and when running Valve games like Team Fortress 2 it sometimes drops to 30-45 FPS where in most areas it gets 60FPS, but I mean this is a card that can easily handle Crysis, it should be getting 100-150+ FPS everywhere, or are Valve games just not as optimized as Windows counterparts?

I read this card as some compatibility issues with 2006 Mac Pros, is this the case?

Finally, I also read Lion has bad performance in games with compared to Snow Leopard, would going back to 10.6.8 yield better performance in all areas?
