Correct me if I’m wrong, but steam has a dead space 3 listed as released in 2013.

I may be wrong, but doesn’t valve usually perform maintenance for steam on Tuesdays? Maybe that’s to blame?

Ridiculous statement. I’ve got an rx 7900xtx and a ryzen 7 7700x with 64 gigs of ram @5600mhz and the fucking game barely ever hits 144fps. Usually it’s sitting around 100-110 fps which is playable for sure, but literally every other game I’ve played on it has had no problem staying nailed at 144fps. This is at low-medium settings BTW (for starfield).
