Probably one of the more exciting releases of Proton lately, with lots of what was previously in Proton Experimental now in the main release with Proton 6.3-8 out now. Be sure to check out our full Steam Play guide if you need more info.
A big addition is the start of support for BattlEye games. Before getting overly excited though, this is just the start of it with only Mount & Blade II: Bannerlord and ARK: Survival Evolved confirmed to be supported by Valve. This is what was previously announced, with developers only needing to get in touch with BattlEye to have it turned on.
We also have the older CEG DRM now hooked up and working, bringing with it more classics working that relied on it.
On top of that there's even support for NVIDIA DLSS for games that use DirectX 11 and 12, although it still needs you to make some manual adjustments to turn it on for now which includes using this launch option PROTON_ENABLE_NVAPI=1 %command%
and also setting dxgi.nvapiHack = False
in a DXVK configuration file (guide).
Here's the list of newly playable Windows games on Linux:
- Age of Empires 4
- Assassin's Creed

Quoting: Rob-RetroQuoting: Comandante ÑoñardoIs there a list of CEG games?
No, i tried searching and found nothing helpful, but did find out that FEAR 3 and HomeFront use CEG and now run and work.
Game with CEG that work for me are:
Aliens vs Predator 2010 (DX11 mode)
Fear 3
HomeFront
The Bureau - XCOM Declassified (DX11) - bad performance, DX9 mode is worse
Call of Duty: Modern Warfare 2 - works great, starts in low resolution and have to wait until your in-game to set options
Games with CEG that run now but have problems:
BioShock Infinite - Random Freeze crashes
The Darkness 2 - runs but has no voice audio
Duke Nukem Forever - runs but crashes randomly with a crash report dialog box with no text displaying
Just Cause 2 - only loads to a blank black screen and have to force close the Game
Did find this list: https://gist.github.com/Plagman/eac7cf27885df24dec48f1477a447e1f
Hope that's of some help.
Just Cause 2 will will minimize on launch and you cannot focus it unless you use %command% /borderless=1
I have been playing it recently. Picked up from my last save which was around 10 years ago.

Does not minimize for me, just loads for a bit to a fullscreen black screen, and then nothing, no hard drive access nothing, then i have to alt-tab or win key (gnome desktop) and press the stop button in steam to kill it.
Just a shame that proton 6.3-7, 6.3-8, Proton Experimental, and all Proton-GE i've tested has broken HomeFront 2, all Proton 6.3 up to -6 worked without a problem, now with -7,-8, etc it will crash to desktop on the Prison level every time.

Just Cause 2: Crashes. The borderless trick mentioned in another comment didn't work for me.
Saints Row: The Third: Runs, but has this weird issue where the game pauses for a second every ~10 seconds. Not very playable as a result. :(
Duke Nukem Forever: Seems to have the SR3 freezing issue but only on the menus. Launched taking up 1/4 of my monitor for some reason. (Switching resolutions fixed this.) Gameplay is... well, it seems to run as intended. I can't call it good since the game itself isn't very good, and Proton isn't going to fix that.
Quoting: Comandante ÑoñardoI just tested Homefront and it works, but it start minimized and if I don't maximize it quickly, it keeps playing the audio, but I can not play.
Works fine on Gnome 41.1, did not have a single problem and have now played from start to finish, its a short'ish game compared to Homefront 2.

I use Cinnamon. I had to use protontricks and config the game prefix for to use a virtual desktop matching the monitor resolution.
I just tried another CEG game, Sniper Elite V2 and the game laucher load, but the game doesn't.
Quoting: obscurenforeignJust tested a few CEG games I have (I was looking forward to Valve figuring out how to support their own DRM)

What video cards are you guys using? Also, I forgot but I think I also did a couple proton tricks for Just Cause 2.
protontricks 8190 d3dx10 d3dcompiler_43 d3dcompiler_47
Quoting: Rob-Retro@m2mg2, Nvidia RTX 2060 with driver 495.44.
Might be worth trying nvidia 470. I ran into problems running games specifically with proton on 495, but those went away when I downgraded.
