... what?

Gaming on linux, in general, has been as performant or more performant than gaming on Windows for like... a year now.

Especially on older hardware, especially for any game that's 6 months old or older.

You'd want to actually benchmark this to be accurate as to how much this improves things.

Basically, this is making a significant section of FSR 30% more efficient. Thats not the same thing as '30% more frames', though it might approach that at lower resolutions or lower game detail settings, while using FSR.

More or less, I'd guess that this means that if you previously could run a a game at whatever settings with say, performance FSR preset, you could probably now bump it up to balanced, and get roughly the same frames that you used to have to drop an FSR preset level to get.... probably only up to 2K / 1440p though.

But thats entirely just me guessing from having fucked around trying to optimize Cyberpunk 77 on a steam deck, shit's too complicated for me to fully understand or reason out with a better explanation.

Uh lets see, also this should theoretically carry forward to RDNA3 as well, as it also makes user of this same thing thag's been optimized...

So, that would include more gpus, and, the Steam Machine, which is going to be using and RDNA3 APU.

Oh right, probably also worth clarifying that this update is not currently out, not just yet. Looks like its slated for February, probably around the time the Steam Machine comes out, would be my guess.
