The compatibility of modern games has been tested by members of the Mac community and the results are better than originally anticipated. Although lack of Bootcamp support still means that you’re limited to a very small number of games, the performance isn’t bad all things considered.
Many popular games like World of Warcraft, XCOM 2 and Total War run quite smoothly, even with all the settings cranked to high/ultra. Some newer games like Borderlands 3 managed to achieve 30-40 FPS on average at 1080p using the medium graphics quality preset.
The more intensive games like Shadow of the Tomb Raider, Deus Ex: Mankind Divided, and FF XIV are a choppy mess though. Not unsurprising considering that you’re looking at an integrated graphics processor. Regardless, this means that optimizing games for new Apple hardware shouldn’t be too hard, and some of the more played games should at least make their way to Mac.
