…Sure, Apple machines aren’t exactly en vogue when it comes to playing video games, but Cupertino’s ultra-high-resolution Mac simply begs to be put to the test. We loaded up Windows 7 on a MacBook Pro carrying an NVIDIA GeForce GT 650M with 1 GB of VRAM, the stock 2.3GHz processor and 16GB of RAM (upgraded from the vanilla 8GB configuration) and put it through its paces to see how it performs.
An interesting batch of tests that show the Retina Display-equipped MacBook Pro is an able game machine on Windows. Also worth noting that some games which run on both Windows and OS X run faster on Windows than they do on OS X.
Any stats?
Plenty in the linked article.
Windows just has better graphic drivers.
Civ 5 on OS X runs ok. On windows 7, same machine, the game flies!!!
That’s it. Apple simply hasn’t put the effort into optimizing their drivers for gaming. Given that most gamers buy PCs, I’m not surprised.
