Games are technically run inside a virtual machine because of differences in how Apple Silicon and x86 systems address memory—Apple's systems use 16 KB memory pages, while x86 systems use 4 KB pages, something that causes issues for Asahi and some other Arm Linux distros on a regular basis and a gap that the VM bridges.

Rosenzweig's post shows off screenshots of Control, Fallout 4, The Witcher 3, Ghostrunner, Cyberpunk 2077, Portal 2, and Hollow Knight, though as she notes, most of these games won't run at anywhere near 60 frames per second yet.

"Correctness comes first. Performance improves next," she writes.

I mean it more in terms of wider API support than in terms of outright performance. GPTK games, when they work, certainly run faster.
