*Assuming you can find games that even work on a Mac.
The Macintosh gaming scene received a boost earlier this year when Valve announced they were bringing Steam, along with their Source games like Half-Life 2, Team Fortress 2 and Portal over to Mac OS X.
I was expecting to see Adam (the only person I know with a Macintosh) on Steam a lot more, and maybe even playing games with me. Before he'd have to boot into Windows and so it was quite rare we'd ever have a game together. I was thinking great, now I'll see Adam on all the time and we can play some TF2. I was wrong however, I haven't seen him logged in on Steam once. Maybe he just doesn't feel like playing games he played on the PC 5 or 6 years ago.
Or maybe there's another reason. Anandtech recently did some benchmarks. Let's just say, the results aren't good for the Macintosh.
On a 2010 MacBook Pro, Half-Life Episode 2 runs 54% faster under Windows than on OS X. Now that's a fairly low-end system. Let's be honest, it's a laptop. Laptop = weak graphics.
How about on a high-end system? Something like a computer with 2 x 2.93Ghz Quad-Core (eight cores in total) Nehalem Xeon processors, 6GB of RAM and a GeForce GTX 285.
Windows gets, quite literally over twice the framerate at some resolutions. Ouch. Maybe this explains why I've not seen Adam joining the Gamercast weekly TF2 matches, maybe it just runs too slow.
That's not all that's bad with the Mac OS X versions. The graphics are foggy and have quite obvious texture banding in some locations. So not only is it drastically slower, but it also looks worse.
If you wanna play games don't get a Macintosh.
