For any of you who may have been looking forward to The Outer Worlds 2, as of right now if it can be launched on Linux, it's not simple. I have a preorder and was able to get through shader compilation fine, set my gamma... and it stuck there. The mouse continued to move and music continued to play, but the game would not advance.
Running Steam from the command line so I could see errors, when the hang occurs, the terminal window is spammed with err:winevulkan:signaller_worker wait timed out with non-empty poll list. Searching didn't turn up any solutions. I've tried with Steam's own Proton Hotfix and with Proton-GE-21 with the same results, so unless you feel like you know how to handle that particular issue or have found tips on getting it to work (it's not out yet except for pre-orders, so there's nothing on ProtonDB), I would recommend avoiding The Outer Worlds 2 pending news.
No good, but thanks for the tip. My remarks on Doom: Dark Ages were also from just prior to release. There are a fair few games that just work with existing Proton at this point.
I don't pre-order games, to play in early release. While its true that some games you'll never get running on Linux regardless of used Proton, generally early release games however, are known to be a non-starter, so I avoid the early growing pains, attached to said games.
I waited months for DTDA to go on the fall sale, paid a much better price in doing so, and I've been enjoying the heck out of it. I got over 30-hours into the game so far, I will likely have 40-hours upon finishing it for the first playthrough.
Most of the games I've gotten via pre-order or purchased at launch in the last year or more have worked with Proton immediately. Doom: The Dark Ages, Borderlands 4 (performance notwithstanding, as that's an issue on Windows as well), Titan Quest 2 early access, Path of Exile 2 early access, Clair Obscur, Split Fiction, Orcs Must Die: Deathtrap, Metaphor Re: Fantazio, Yakuza franchise games, Persona 3: Reload, Dynasty Warriors: Origins, and more. Honestly, this is the first game without a known anti-cheat to NOT work for me, and I picked up everything on that list either at launch or so soon after it didn't have Proton changes or patches fixing them. (Doom: The Dark Ages did have a weird issue with frame generation for a long time that turned the whole screen purple, but turning that off solved it easily.)
As for cost of pre-orders, I've mentioned working in the industry in the past. Some games I get as a perk, as soon as they're available to the public (early access, pre-order, whatever). On such occasions, I try to test them and let people here know how it goes, to inform their own decisions.
Fix instructions: Edit GameUserSettings.ini to change bHardwareRayTracing=false to bHardwareRayTracing=true.
This ini file is in /AppData/Local/Arkansas/Saved/Config/Windows, which... is complicated a bit by using Proton. Assuming you're using Steam, the ini will be in that directory, but under your WINE prefix. By default: ~/.steam/steam/steamapps/compatdata/1449110/pfx/drive_c/users/steamuser/AppData/Local/Arkansas/Saved/Config/Windows
This trick comes courtesy of Corey Trevor on Protondb. I sure never would've found it. Note that my personal testing has only gone to the main menu so far, but it has enough working reports on ProtonDB for a gold rating now.
