Windows Was The Problem All Along - Dave2D
We could obviously compare performance between windows and steamOS before on the steam deck, or between windows and Bazzite on other handhelds. But this is the first time we have had official windows and SteamOS builds for the same hardware.
I was kinda joking, but the game still stutters and has fps drops regardless of the hardware it’s run on. Digital Foundry has a pretty scathing performance review of it.
It’s certainly playable on good hardware (assuming you aren’t super bothered by dips), but it also performs way worse than it should at any hardware level.
I don’t consider the game a good performance benchmark for any piece of hardware because it’s performance is abnormally bad, and there’s no hardware where it can run without issues.
