Steam Machine will play the majority of Steam titles 'at 4K 60 fps with FSR', but some will require more upscaling than others, Valve says

Valve has broken its silence on its forthcoming hardware line-up, offering new details on the Steam Frame and Steam Machine, as well as an answer for why it hasn’t revealed pricing and a release date yet (hint: blame the RAMpocalypse). It has also dropped some information about the kind of performance we can expect on the Steam Machine.

“In our testing the majority of Steam titles play great at 4K 60 fps with FSR on Steam Machine,” Valve writes in a new FAQ. “That said, there are some titles that currently require more upscaling than others, and it may be preferable to play at a lower framerate with VRR to maintain a 1080p internal resolution.”
