This is fantastic news for Steam Deck users! FSR 4 coming through Proton Experimental could be a game-changer for performance on so many titles. I'm already imagining how much smoother things like Ragdoll archers or even some of the more demanding AAA games will run. Hopefully, it lands soon and is as effective as we all hope!

In terms of image quality, how does it compare to previous FSR versions (leaked version fsr4 int8, fsr3, etc) and using no fsr at all? Is it a notable improvement? Does it finally get rid of problems of image stability and shimmering mostly? Have you tested any other tested games with it? Thoughts on how it compares to intel XeSS DP4a?

Has it finally gotten to a point where it's good enough to enable automatically for every game by default without thinking about as there are no major concerns / issues left?

At what wattage?

In hindsight, it was good to get your halo framework desktop with 128GB before the price hikes. What you had to pay for it, is now almost how much people are paying for 16GB steam machines. I am envious.
I haven't tested it that much, but in theory "FSR 4.1.1 performance" is about the same quality as "FSR 3.1 quality", so all in all FSR 4.1.1 is great.

Wattage, I don't remember. I'll have to try again another day.
Paid 2400 € for it. Now the same components are 4000 €. Totally crazy.

Quote from: what about RDNA3.5 iGPUs? on June 25, 2026, 08:34:08AMD, what about all the countless RDNA 3.5 iGPUs, like also in the expensive Strix Halo PCs? Wouldn't they especially profit from hardware-based upscaling? (it's a rhetoric question) Even if it's a 720p resolution, it looks much better than FSR3.x:

Just ran Horizon Zero Dawn Remastered with a Framework Desktop (Strix Halo 128 GB), and FSR 4.1.1 is working correctly:

My TV is 1080@60 (so sorry, I can't test 4K@120), I put the highest preset, and activated all the FSR goodies.
Plenty of FPS to spare. Fan not audible, so it's sipping very little power.

Valve appears to be testing AMD FSR 4 support through Steam and Proton Experimental, potentially allowing many FSR 3-enabled games on SteamOS and Linux to access the newer upscaling path without third-party tools, a move that could benefit other similarly configured handhelds too.
