According to the post, they were running the x64 version via emulation on ARM. Not a native ARM version. That’s a lot more impressive to me.
That’s fair enough, but the article is wrong in other places.
The game has been developed exclusively for x86 systems: exclusively those built on x86 chips—Intel or AMD chips.
That is not true. See here. It is ARM native for Apple silicon as interpreted by MacOS’s own activity monitor. There is no Rosetta translation going on here.
The article continues:
But Apple has a weak spot: gaming. Almost all games today, be they intended for PC or console, are built for x86 systems. Apple had sought to sort of get around this with the Game Compatibility Toolkit, which is a tool to get games running on ARM, but it’s not being used to actually bring a larger gaming library to Apple devices just yet. Qualcomm’s comparable tool, however, is.
So I’d take whatever else they state with a bucket of salt, they’re just wrong and they didn’t bother to check.
On the one hand, it’s impressive it “just works” at all considering it’s probably the biggest question for ARM PCs. On the other hand, this game in particular runs at a higher framerate and resolution on their main competition (M3) . Kind of a weird flex.
