Runs well with Proton 8.0-2 and no tweaks. I experienced one random crash (with an UE4 crash report dialog) which seems on par with Windows users. Minor audio crackling during cutscenes. Performance is fine with 40-60 FPS with all settings on Epic except AA off @ 4k resolution. Alt-tabbing resulted in an invisible mouse cursor once (but was usually fine). Alt-tabbing again resolved the missing cursor without restarting the game. Keys can be rebound freely with conflicts marked, but the conflicting binds not erased (a godsend for anybody that wants the default key positions with a non-QWERTY keyboard layout).
Fun until you get to the broken cab ride.
Slight crackling, barely noticeable. Conspiciously absent voice lines for random interactions (story voiceovers always work) and unable to play radio in car.
Game would not recover after alt-tabbing, and sometimes would not allow other windows to render properly after alt-tabbing until the display-manager was restarted.
Game runs at more or less the same level of slow regardless of most graphics settings. The only thing that made a big difference was Fidelity FX CAS which set to a static 70% doubled the framerate.
Rare crashes for the first 9 hours, then during a cab ride required for the main story it crashes every time, unable to progress.
Proton 5.13-4
Hard freeze in the character creator
Appears to be crashing the GPU driver - requires a full restart to recover.
Absolutely critical to disable strand hair. That particular setting causes hard freezes / GPU driver crashing within a couple minutes of play that require a full reboot to regain control. I have experienced 0 crashes with that setting disabled.
Performance was really bad (sub-20 FPS with audio crackling and stutter) until I updated the motherboard's BIOS. Now getting 70+ FPS with most settings on Ultra or High (strand hair OFF)
Update to my previous borked report before solving the hard freeze/crash.
Gameplay works perfectly. Very fun game. Watch cutscenes on YouTube.
Pre-rendered cutscenes (such as the one that ties to play when starting a new game) do not work, showing only a black screen. Hold space to skip.
Proton 5.13-1
Unique game runs like native
Public playtest is a bit buggy (unsurprising for pre-release), but I do not believe any of the major bugs are Linux specific. Overall feels like native with good framerate on default ultra, only a little frame-y in busy fights. In-game chat often fails to come up when pressing enter and messages are cut off on right hand side - likely not be Linux specific either but nobody else was complaining about that one.
Proton 5.13-6
Proton 5.13-4, might as well be native. No crashes, no issues.
Select the "tester" branch under Steam's beta options
Select the "tester" branch under Steam's beta options or the game will crash while loading "Biodome Sector A" midway through the campaign. If a black screen occurs at the start of the campaign, press space to start. Using "tester" branch, I was able to play through story completion with no issues.
4.9-GE-8-ST GloriousEggroll
Locks up frequently on the Mary Celeste. Seems to freeze a little less often with Proton-6.1-GE-2 and Proton 5.13.6 but the cutscenes are a distorted mess or don't play at all respectively on those Proton versions. Luckily the meat of the game (navigation, space battles, ground battles) is rock solid.
Requires mf_install (https://github.com/z0z0z/mf-install) to play cutscenes with Proton 5.13-1.
Proton-5.11-GE-3-MF does not need this to play cutscenes, but has no audio outside of the menus. Proton-5.9-GE-8-ST crashes upon startup after showing the Unreal logo.
Slight crackling on audio, not enough to be a problem.
Keys that have an alternate bound can only be activated by one of the 2 keys. Unbind the alternate to "fix". The keybind option for "Move Back" is internally disconnected from backwards movement (and the menu option which has no effect anyway is, by default, unbound). This means although 'S' will move back, it cannot be rebound. All the other keys can rebind properly, but this bug prevents fully remapping to alternate keyboard layouts (such as Dvorak).
Performance seems low (even considering 4k resolution) at 25 FPS (all ultra, no AA) to 50 FPS (all low, no AA) considering the quality of graphics even at ultra is somewhat dated. No Windows to compare against.
When tweaking performance options, reload last checkpoint after making changes. Some changes (such as shadow quality) cause performance to tank down to 1-2 FPS until reloading.
View distance had a drastically larger effect on FPS than any other setting.
Works flawlessly with default Proton 7.0-2
Even though the game is at 4k resolution, internal renderer appears to be somewhat lower - looks a bit pixely. No reason to believe this is Linux specific.
