Last time I tried to play Stray on Linux Mint on my laptop while connected to 4k TV, I ran into severe degradation unrelated to thermal throttling. I had to tweak the resolution down a lot and even the graphics. I recently went back to using Windows on the laptop because of an unrelated network speed unreliability problem on Mint, and when I tried Stray, there were no issues. Before this, I had even installed Stray on my gaming PC to stream from the laptop because of how laggy the performance was.

EDIT:
Okay so I suspected it was thermal throttling, even though I have a cooling fan. Turns out not using a cooling fan is better than using a cooling fan at the lowest setting. At the highest setting, the cooling fan is too loud but the game performs still slightly worse than on Windows.
Linux Mint being the top distro recommended by searching the internet really does not help the broader “year of the Linux desktop” goal. Like I think we are there for the right distro if you skip disk encryption and opt for home drive encryption, but that itself is not easy info to come by.
