How is your iMac handling TF2 (or any source game)?

I have a 2009 iMac 27" i7 ATI 4850 and I play TF2 with everything at maximum

 

I have no idea, how can I check it?

 

What iMac do you have? If you have the 4670 or higher you can max TF2 easily.

 

I'll report back tomorrow with the results as I am out until Monday!

 

Then you'll be more than fine. The 6750m is more than enough for any valve source engine game. Assuming that's what will be in the next one. Which it could very well not be. But chances are it will be something better.

Ok, I'm back

Playing 2Fort with 23 players with everything at maximum but AA that is set at 2x (there is no need for more) gives me 59-60 frames, so performance is pretty good

 

I have the high end 2011 27" iMac and it handles Source games excellently. I haven't installed TF2 yet but I've been playing Diablo 3 a lot lately and it doesn't even break a sweat running it on high settings.

 

Buttery smooth on my 2011 27" i5, same with L4D/L4D2

 

Its rather that Source is a rather old engine and games based on it are not very demanding The iMac is perfectly capable of dealing with them and also newer games, although you will quickly run into limitations of the lower-end iMac GPU when gaming at 1080p. The higher-end 6970M is a monster though and can run almost everything at ~30 fps (native res) which is enough for me.
