gamemoderun %command% -vulkan
on my laptop, the game was running at 60hz using OpenGL. switching to Vulkan in the launch options fixed this issue and i was able to play at 144hz :D
*aside from a hertz issue, the game ran excellently well out of the box
Perfect
At the very end of the game after Wheately said "the end" post credits it crashed. No clue why. Just the one crash.
Played full game and co-op, no issues at all!
-vulkan
Works fine on both vulkan and opengl. Coop works fine too.
-Vulkan
The game went between my monitors on my 2 monitor set up. Opening in Vulkan fixed this.
great game and works great on linux
startup was kinda weird: it fullscreened and unfullscreended itself a few times
The game will crash after the final cutscene of the singleplayer campaign, but I don't think this issue is exclusive to the Steam Deck.
Note that the game is already on max settings by default (aside from AA which can be changed from 4X to 8X if you care that much).
Proton works better than native
Native had a scaling problem where mouse would not be in-line with the game (other smarter peole also reported this) Changing from linux runtime to proton experimental fixed this. Runs as expected
Flawless native
No issues OOTB for me on native.
Performs even better when you enable vulkan backend with -vulkan flag
On native, audio kept reverting to surround 5.1
On native, fullscreen locked refresh rate to 60 hz and windowed/borderless windowed caused the game to be centered between both of my monitors rather than being centered on one of them
Runs great with Vulkan on a dual monitor setup (game is shown on one 1080p monitor) with no issues
-vulkan
Whatever Portal 2 uses by default to run on Linux (I assume OpenGL), it was causing major issues for me with my dual monitor setup. It would think 3840x1080 is the default resolution, but only display at 1920x1080, causing odd issues with mouse responsiveness and general playability. Switching to Vulkan using the launch option resolved all these issues, and it correctly recognized 1920x1080 as the native resolution ingame.
The native did not work correcly. There were issues with the placement of the mouse cursor in the menus and the graphics were squished. After switching to proton experimental all issues were resolved.
KWin Window Rules
Used KWin Window Rules to fullscreen it properly after setting the Game to run In windowed mode
When running on multiple monitors there are some issues with windowing and fullscreen
Natively, the game would treat both monitors as a single one and launch in 32:9, but only actually launch on one of the monitors. For me it launched on the left one despite the right one being the primary. Fix for me was switching to Proton and now it functions as expected.
With the small tinkering I did, the game runs perfectly. Just not when you run with native linux binary. For reference I use KDE Plasma 6.3.5 using Wayland
Launched in fullscreen across both my monitors, had to go into settings, set it to be windowed, set the correct resolution and have Hyprland fullscreen it
Steam coop worked without issues
I didn't recommend this in my previous protondb review, as it had windowing placement issues on xfce-labwc environment (wayland).
but I came back to update this review, as I just switched to KDE plasma 6.5.3 (KWin-wayland) and re-installed the game. result: first launch no configuration or setting modification at all, and the game placed itself correctly on my primary monitor, and no cursor offsetting at all.
so if you face any multimonitoring issue with this type of game, go and give KDE plasma a try, because this game will work on it with zero hassle
Great OOTB
The final cutscene ends with a black screen, you get the achievement tho so you can just go back to main menu and exit the game
mangohud %command% -vulkan -w 1920 -h 1080 -novid
Broken resolution and fullscreen mode with no parameters
Works fine
Works fine
The game works perfectly, there are no performance problems. There are some issues with resolution and windowed/fullscreen mode without options, but they are incredibly easy to fix. As I understand it, the -vulkan parameter fixes everything. Multiplayer also works, all online functions are also available.
To my surprise, the native version works via DXVK, I have not seen this before! I double-checked that the native version is running, and it really is.
Having too many Steam Workshop subscriptions causes stuttering and crashes both on native and Proton
-vulkan
Slight stuttering
Crashes after 5-10 minutes
Game crashes when attempting to make purchase from the in-game Robot Enrichment Shop
-vulkan
Without -vulkan, game runs on leftmost screen
Built-in voice chat doesn't work on native
gamemoderun %command%
Might be a wayland issue, but the game window was in the centre of both my monitors and the mouse was offset. This was only on the native version. I fixed it by switiching to proton experimental
Mouse was offset in Fullscreen
I was messing around with the resolution on fullscreen on Proton Experimental. I haven't experienced crashes ingame.
used official with gyro layout with minor tweaks to back button binds and gyro sens
occasional stutters for no real reason
runs the same as on pc, no issues
It just works! No tinkering required, as it works without any severe issues and performs better than on Windows!
I haven't played Co-op tho, but everything else works flawlessly! Either way, you'd be good playing this on Linux.
Works great natively but the level editor is broken outside of Proton.
-vulkan -w 2560 -h 1440 -novid
so maybe its just a wayland thing but I just gave up running this fullscreen properly in a multimonitor environment. game puts itself on left secondary portrait monitor (1080x1920) and cannot change monitor output at all. tried proton version change, experimental, steam runtime, no compat mode, vulkan etc. none of them worked.
this was on xfce labwc (wayland), and it probably works on xorg-server
due to incorrect sizing as described above, the mouse is having an invisible offset. its a side effect of the incorrect portal 2 window display output placement and sizing
can recommend if you are on xorg-server
Native version has some odd control quirks, but is otherwise playable. Proton version fixes all of that
Slight issues with multi-monitor setups (on Native version) but is otherwise perfectly fine!
If you have a multi-monitor setup the game will get confused and have the resolution's width set to the width of every monitor combined (e.g. with two monitors that both are at 1920x1080, the resolution will be at 3840x1080). You can fix this by clicking any of the slider's arrows and the game will correct itself, with the added issue of having the mouse collision for the menu items being offset.
I originally played the campaign on a single-monitor setup and everything worked just like Windows, the windowing issue above only happens on multi-monitor setups, it's a minor annoyance but the game is otherwise still perfectly playable (you just have to deal with the weird offsetting issue, some people have said that using the -vulkan launch option fixes that issue, however I have not tested that as of writing this).
