PayPalValve snuck out a Release Candidate build for Proton 8.0-4 last week, which brings with it many improvements to the main stable version of the Windows compatibility layer for Steam Deck and desktop Linux.
It's in the RC stage, as Valve are looking for feedback on any issues that weren't present in 8.0-3. Currently there's not many comments, so perhaps it needs a few more eyes to test your favourite games and report back any new problems. To access it select Proton 8 in your Steam Library, go into Properties -> Betas and select the "release-candidate" option.
Here's everything changed in it (which may be different when fully released):

There's no set date for Proton 8.0-4 to release for everyone. When Valve did the RC for Proton 8.0-3, it took over a month to release in full. And looking back, some previous RCs took even longer but then there's been other times where it was only a week. So basically "when it's ready".

I always wonder on these releases... Are they better than using Proton Experimental by default? I've used both of them and I don't really see any difference at all.
I've heard of Proton Experimental being less stable, but did not experience anything like that at all.
Would there be any benefit of switching one or the other?

Though I usually stick to Experimental (or just leave whatever's been set for a game on the Steam Deck), I've had (rare) occasions where a Proton Experimental release will break a game that worked fine before, whereas my understanding is that the numbered releases are guaranteed to keep working with whatever was set in stone when they were released. My takeaway was to just use what works best for you.

I think 70% to 80 of my Steam Library now works on Linux.
Any games out there that people are getting impatient for Valve to find a fix for??
(not including the anti cheat stuff here as I have pretty much given up on them)

Quoting: Craggles086Any games out there that people are getting impatient for Valve to find a fix for??Anniversary Collection Arcade Classics. It's a collection of Konami arcade games, and I grabbed it in the Fanatical summer sale without checking ProtonDB first (which I otherwise always do), since I expected it would work under Proton like the Castlevania and Contra collections do. Wrong!
It's possible to make it work with some hoop-jumping, but I specifically bought it to play on the Steam Deck, and the only current workaround for it requires you to play in desktop-mode, which isn't optimal.
Looking forward to when they get it working - I do like to support official re-releases like this when they're made available to me, after all.

Some of them, like the Neptunia series can be really rough to get to run properly with cutscenes, music, gamepad and proper frame rates.
