Stable or normal versions of Proton barely work for this game, lots of input lag, fps drops and stuttering. GE-Proton is a must.
Crackling and bugging out on loud explosions
Screen flicker on some textures
Stable or normal versions of Proton barely work for this game, lots of input lag, fps drops and stuttering. GE-Proton is a must.
Switched to launch options to tell the game to use my dedicated GPU, otherwise no issues from start to finish.
PROTON_ENABLE_NVAPI=1 DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 3090 Ti" %command%
Did not launch without launch options, possibly tried to use CPU instead of dedicated GPU.
В целом играбельно пройти сюжетеу можно но не более импут лаг есть и целиться из-за этого проблемно
Зерностость от FSR
Очень сильеыц импут лаг
Были фризы не значительные
При переходе в другую локацию просто черный экран и нет значка загрузки чтобы исправить перезапускаем игру и вы грузитест в новую локацию бывает часто проблема эта
The textures on NPC faces look weird. Some black textures on the teeth as well.
Had really low FPS until switching to GE-Proton9-21
Had one crash on the first mission.
Had to set everything on Low settings and lock the framerate to be able to play comfortably in 1440p. Still enjoying the game.

Im Grafikmenü auf Nvidia DLSS umgestellt. Danach lief es flüssig.
Die CPU wird genutzt statt Grafikkarte bis man umgestellt hat auf DLSS
It works.
If you are on nvidia as of March 2025, directx12 games lose 20-50% performance.
With Proton GE 9-26, it just works. The game installs and plays just like on Windows. All settings work, no crashes and no bugs. A perfect experience from beginning to end.
PROTON_ENABLE_NVAPI=1 DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 3060 Ti" %command%
Default game woudnt launch beyond initial startup logos. Specifying GPU in launch options was necessary and changing resolution in game menu. Game started in max resolution and fullscreen window mode, wich caused massive lagging.

Game would freeze when starting up until I switch to Proton Experimental, and even then first boot takes forever. After the extremely slow first boot, everything works fine there after and subsequent boots are fast. This happened on Windows 11 also, so doesn't seem to be a Linux issue.
Tried proton experimental and proton9 first but it was a bit laggy. changed to ge-proton and lag is gone.
Didn't have to do anything extra the game just runs.
I think in general the game isn't optimized that well and not a Linux/Proton issue but I still enjoyed it.
Changed the executable from RoboCop Rogue City\RoboCop.exe to RoboCop Rogue City\Game\Win64\D3D12\RoboCop-Win64-Shipping.exe, otherwise it didn't launch
I'm gonna classify as slight performance problems because they didn't make the game unplayable by any means; but twice I had a stutter that lasted between 5 and 10 seconds. They didn't occur during action sequences though, just during exploring. Also, during the third visit to the city, I had a bit of an FPS drop, but it was minor.
The thing is, it runs completely fine, I completed the game and even enjoyed it (despite the game having so much ghosting I spent half the time asking myself it wasn't playing Ghost Busters by accident; but then again, it's Unreal Engine using TAA with no other option of anti-aliasing). I'm just not sure if the average user would be fine with, or even think about tinkering with the executable, even if it's not a hard fix.
With the latest Proton experimental, this now works out of the box - including videos - without needing any launch options.
Game installed from GOG via Heroic Games Launcher. Works OOTB without any special settings and performance seems to be about as expected.
My default is Proton Experimental and the game froze up and crashed during the first mission after about 15 minutes. I switched to GE-Proton9-14 and got through the rest of the mission and continued playing fine without issue.
Just worked, no tinkering needed
Played through whole game without any issues.
I installed the 200+ PFS and Slow Loading Texture mods and it resolved all my performance issues.
The lightning-engine us prone to 'freaking out'. You'll notice it sometimes makes the environment 'shimmer'. Nothing gamebreaking or too distracting, though. FPS is low by default, especially during cutscenes. This can be overcome by adjusting your settings.
Will it run as good as on a Series X or PS5? No, obviously not. I've played through both those versions, though, and found the Steam Desk-version to be quite impressive and flexible. These are my settings. which give me a stable 30fps (which is quite enough), bar some drops int the (high) 20's during heavy explosions or big battles, but that lasts only a a fraction of time. The warehouse battle against the UED's remains a stresspoint, though. Cutscenes may occasionally drop to the mid-to-high 20's, but that doesn't distract.
- Steam performance menu: frame limit to 30fps
- Resolution: the one below 1280x800 (can't rememer what it is exactly)
- View Distance: far
- All settings to medium
- Reflections: SSR
- Resolution scaling: 50
- Upscaling: TSR
Can't speak for versions before patches as of august 2024, but this runs acceptable.
But.. if Lewis calls me 'partner' one last time, there will be... trouble.
PROTON_ENABLE_NVAPI=1 DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 3090" %command%
Videos just display as a white texture. I've read that for some games enabling shader caching will enable videos transcoded into a working format by Valve, but that didn't help here.
Default Proton and experimental both crash on startup.
DXVK_FILTER_DEVICE_NAME is non-optional even on a desktop with a single GPU - without it I think it tries to use llvmpipe so it's unusably slow.
DOA :(
Nothing I tried made any dent, it throws an window up that just says "Error" and then exits.
I guess I can't edit my prev report, but I figured it out. Disable all upscaling then exit game. Add launch option "--use-d3d11".

Step 1 - Disable all upscaling then exit game. Step 2 - Add launch option "--use-d3d11". Step 3 - Launch the game, and all graphical issues are resolved
It works perfectly fine on my steamdeck, so I am assuming its my driver versions on my mine pc causing the issues. Maybe an update will fix

Textures, objects, etc disappear, reappear, depending on the facing angle of character
Not playable without costant graphical glitches and oddities with the latest updated garuda linux as of 6/20/24. I will have to use my steamdeck to play the game through until a driver update(hoping) possibly fixes it.

With experimental proton and proper selection of my GPU the game ran very smoothly with no problems.
It failed without these changes. Most probably mainly because this game really needs to set the used card when one also has the iGPU.
Removed intro videos using the Fast Launch mod
Some weird artifacting here and there
Some weird graphical glitches but other than that, no issues

Runs out of the Box perfect

Could not progress through the Auto-9 customization tutorial due to a non-bound key. Had to force-quit the game. Key bindings got reset afterwards.
Initial loading time was suspiciously long
The game would barely start without the launch options and was unplayably slow
Use "vulkaninfo --summary | grep deviceName" to get the device name to use in the launch options
DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 3070 Laptop GPU" %command%
the only way to launch the game and get past the intel logo is to use this: DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 3070 Laptop GPU" %command%
you can find your device name using the command: vulkaninfo --summary
For some reason, without the above, it was defaulting to my igpu and crashing.
Runs perfectly, except FSR.
FSR is causing a lot of shimmering. without it enabled it runs perfectly.
Yesterday I wrote in my report I could not get the game working with either GE-Proton8-32, Proton Experimental or Proton 8.0-5 but only with Proton 7. Today I learned the culprit seems to by that the PC's iGPU got selected instead of the Radeon RX 480. I found there are 2 ways do make the game work:
- either explicitly select the Radeon RX 480 using "DXVK_FILTER_DEVICE_NAME="AMD Radeon RX 480 Graphics (RADV POLARIS10)" %command%" as launch option
- or just disable the iGPU in the BIOS
With both of the options the game runs okay with some glitches with GE-Proton8-32, Proton Experimental and Proton 8.0-5!
Fun, works with the correct parameters. Parameters can likely be reduced/optimized, I shotgunned it hoping to make it playable and it worked
Would not load first screen/play the game without launch parameters of: DRI_PRIME=1 VKD3D_FEATURE_LEVEL=12_0 PROTON_ENABLE_NVAPI=1 MANGOHUD=1 MANGOHUD_CONFIG=fps_limit=60 RADV_PERFTEST=sam RADV_PERFTEST=nggc RADV_PERFTEST=gpl __GL_SHADER_DISK_CACHE=1 __GL_SHADER_DISK_CACHE_SKIP_CLEANUP=1 DXVK_ASYNC=1 MESA_VK_DEVICE_SELECT_FORCE_DEFAULT_DEVICE=1 %command%
The UE-Game Game has crashed and will close. Fatal error!
The game starts loading, then it's showing next stuff subsequently:
- Onacon
- Teyon
- Unreal Engine
- Intel Arc Graphics
- Crash... popup showing "The UE-Game Game has crashed and will close. Fatal error!"
I have tried GE-Proton8-32, Proton Experimental, Proton 8.0-5. All with same result. Only Proton 7.0-6 will result in functioning game, though VERY slow!
Doesn't launch or work no matter what I do
I tried many proton versions and even tried x11 and only get a black screen and music.
