On par with Windows. Only using WINEDLLOVERRIDES to get Universal Achievements Unblocker mod to function and gamemode for HDR. I get 45-60 FPS average on Ultra 1440p with ray tracing and DLSS enabled, on par with what I was getting on Win 11. Average FPS increases to 80-120 with DLSS frame gen on.
Use Vortex for mods with a symlinked folder to .steam to set game directory properly within Vortex.

Works right out of the box
No tweaking required!

Sometimes loading into an area like the Imperial city caused textures to not load properly or at all on buildings and NPCs
No problems at all, runs very nicely. Only criticism is that when entering a new area, everything pops into view and the player character kind of drops down into the screen as it loads. Sometimes textures are not loading on certain things, but after running around a bit, they fix themselves.
Doesn't work for me after the newest patch

Installs, run first shader compilation then closes with a UE5 error screen
Repeats every run after this, tested with proton, GEs and CachyOS

Using Oblivion Engine Tweaks for better performance
It's Oblivion, so it's pretty much expected
Bugthesda
Was able to run OBSE64 and UE4SS and I was able to install mods without any issues.

Character selection and modification screen, everytime the user avatar changes there is a momentary but noticable delay before all of the assets appear (e.g. hair)
Stuttering, less than 60fps with frequent drops to 30fps
First run is quite painful. You'll see Steam churn through processing Vulkan shaders for many minutes, then once the game itself loads Oblivion needs to churn through more shaders.
Applied two optimization mods:
- https://www.nexusmods.com/oblivionremastered/mods/1776?tab=description
- https://www.nexusmods.com/oblivionremastered/mods/35?tab=description
Without the two mods, frequent stuttering will occur. Using Nvidia 5090 with settings on Ultra, getting ~40-50 FPS.

It's as stable as Windows.
The game runs as it should right OOTB. I think everyone else here is unaware that this game is a glitchy mess with high PC requirements. I did nothing with steam in the way of launch options or different Protons, instead I've added performance mods (and other mods), the game starts and performs like if you played it on Windows (For better or worse)

Worked out of the box for me, however it has Issues
Framerate outside of dungeons is pretty abysmal without frame generation, and even then its not great. This is however a general issue with game and not Linux specific. The same goes for the amount of bugs and patches that end up making things worse, it is still a Bethesda game after all...

Game launches to a black screen.
Was working just fine, but after recent update, game loads a black screen on Fedora w/ AMD CPU and Nvidia GPU. Main menu music/audio works, but the display is black. Tried updating drivers and rebooting.

Fonctionne sans probleme
Fonctionne parfaitement avec les paramètres par défaut de Steam. Compatible avec les mods. Aucun problème rencontré : le jeu est fluide, les FPS sont stables, sans crash ni autre souci.

Seems to have some frame rate issues in open areas of Cyrodil, but that seems to be a universal problem, not specific to linux.

Works on medium with low frames without anything. To make it playable, especially in open areas - and as others suggested - install these two mods for performance fixes to make it work on higher graphics settings (point blank ultra for me):
These were gone after installing performance fixes!

Unreal Engine crash on startup after version 1.1 patch, game ran well before the patch.
To improve performance to a playable level, used the utlimate engine tweaks mod - https://www.nexusmods.com/oblivionremastered/mods/35
After the forced update to verison 1.1, the game now crashes on startup. After deleting and re-installing (vanilla no mods), the game initially ran it's shader pre-caching. Upon reaching 100% shader loading, it crashed. Now it starts to a black screen and shortly after an Unreal Engine crash screen is displayed.
I've tried both deleting the shader cache and running with versions of proton, but no luck.
Currently it is completely unplayable. Before the patch, I played 30 hours with 0 crashes.

Steam versions of proton don't allow to use DLSS Frame Generation. It's blocked in game settings. Better to use GE-Proton10-4. It has no issues with the game or any settings. Game runs as expected in case of Proton GE.

Installed optimized Engine.ini file
Installed a custom Engine.ini and custom dlss-to-fsr dlls to enable frame gen. This resulted in a much better frame rate than what I was getting on Windows.

One crash so far, in a battle with a bunch of Imps.

Had to lower VRAM limits following this guide - 5GB texture pool seemed to work best https://www.nexusmods.com/oblivionremastered/mods/399
Without, in outdoor areas it would relatively quickly exceed 8gb, and crash the whole system. Suspect vkd3d eats up a bit extra vram which the game wasn't accounting for.
Crashed on using up all VRAM

gamemoderun %command%
Easy to use. No crashes, while in Windows I had common crashes. The only 2 times it crashed on Mint was when exitting the game, which did not affect save files or anything in the game. Could still play normally. Once the frame dropped inside a dungeon and stuck on 20 fps, relaunching the game fixed it. Not sure if it was something related to the game's being not well optimized or with Linux, but on 80 hours of gameplay I got no other issues.

If you're on Nvidia, this game is not particularly enjoyable unless you've got a very high-end card.
mangohud %command%
As usual with DX12 games on Nvidia, there is a performance overhead of ~15--20% on Linux compared to Windows. I can hardly reach 60FPS in the open world at max settings. I get constant stuttering even after installing a mod that's supposed to fix it.
If playing Vanilla: nothing
OR
If playing with obse:
WINEDLLOVERRIDES="d3dcompiler_47=n,b;dxgi=n,b" bash -c 'exec "${@/OblivionRemastered.exe/OblivionRemastered/Binaries/Win64/obse64_loader.exe}"' -- %command%
very rare freezes on loading screens

60 FPS => dropped to 20 FPS often, not playable
I dont get it, why this game has platinium - terible performance. From 60 FPS offten dropped without any reason to around 20, so game not playable. I tried Proton 9 and experimental, nothing change.
E.g. Kingdome Come 2 has much better performance than this on same machine. Without any struggeling with configuration / custom changes etc.

Install and play, no problem with the game
The game runs well and i dont have any issue

Works well, FPS seems a little lower than under windows.

Per any Bethesda game, expect occasional crashing which also apparently happens on Windows
Works perfectly out of the box with proton-cachyos but be warned that frame gen cannot be enabled in the menu. As someone mentioned below, every single time you launch the game you have to open console and enable Nvidia reflex and frame gen. See below:
To enable frame gen: Altar.DLSS.FG.Enabled 1 To enable reflex: Altar.Reflex.Mode 3

You don't need to edit launch options. Fortunately for modders, mods work. I use them, including achievement unblocker.
PROTON_ENABLE_NGX_UPDATER=1 DXVK_NVAPI_DRS_SETTINGS=NGX_DLSS_RR_OVERRIDE=on,NGX_DLSS_SR_OVERRIDE=on,NGX_DLSS_FG_OVERRIDE=on,NGX_DLSS_RR_OVERRIDE_RENDER_PRESET_SELECTION=render_preset_latest,NGX_DLSS_SR_OVERRIDE_RENDER_PRESET_SELECTION=render_preset_latest WINEDLLOVERRIDES="winmm.dll=n,b;" gamemoderun %command%
Not linux related. Game still suffers from the same issues that the windows version does.
My launch command enables the latest DLSS 4 within the game, which by standard I think uses 3.5
From my experience, after enabling DLSS4 with my launch command, DLSS options within the game opened up, and I could enable Frame Gen + Boost. If the options aren't unlocked after swapping DLSS4, then try the in-game commands instead, which others have posted.
Doing so enables Ultra quality and getting 140-180 FPS in the overworld, with a more consistant 170-200+ indoors.
Performance is consistant with Windows version, if not on par then, within a 10% margin slower.
Runs as expected otherwise.

Outside of the launch commands and the occasional black screen issue, there are no other issues that require tinkering.
WINEDLLOVERRIDES="winmm.dll=n,b;dsound=n,b" %command%
Occasional black screen when loading main menu. This is usually remedied by alt+tabing out and back in.

Runs flawlessly minus occasional crashes that also happened on Windows.
Occasional crashes but I had them when I played the game on Windows as well. They were all Unreal Engine crashes.

gamemoderun %command%
Reflections are kinda glitchy, especially water reflections. Both with Hardware & Software Lumen RTX
Maybe it runs a little badly given my hardware; at the high preset with render scale set to 100 it just about manages to maintain 60 FPS. I tested Proton 9.0-4, Experiemental and Hotfix; the game ran the best with Experiemental.

Crash @80% of pre-shader-caching process
- freed some gigs on drives(maybe shaders need as much space as the game?!!.)
-> did NOT help. Even with 50GB minimum free space on ~/ - steams default: crash@80% pre-shader processing
- proton experimental: crash@80% pre-shader processing
- GE-Proton10-3 : You dont have a dx12 grafik card, did not even run the shaders
- GE-Proton9-27: Shader processing slooow.. but finally the game runs!

No Issues Out-of-the-box

Game launches without the need for any startup commands if you play without OBSE and don't care about hardware ray tracing.
eval $( echo "PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 %command%" | sed 's+OblivionRemastered.exe+/OblivionRemastered/Binaries/Win64/obse64_loader.exe+g' )
I needed to do some digging to find a way to launch the game with OBSE, but the above command works perfectly.
To use hardware raytracing on NVidia, you need to allow the game to see your nvidia gpu.
Otherwise works perfectly, didn't need any commands to start and run normally. It even works with mods installed as long as they are just ESPs or texture mods that don't require the script extender.

Tested both GE-Proton10-3 and Steam Proton 9.0-4, the first start takes a bit, both work flawless without audio, input or save issues.
The game runs out of the box for me, without launch options, it runs at the same fps as in Windows 11. On my system I get 60fps in the sewers, around 40fps outside and in some interiors where a lot of entities are loaded, it drops below 15fps (Tiber Septim Hotel top floor during The Lonely Wanderer quest).
I use Linux Mint 22, vanilla, only changed a wallpaper and downloaded ProtonGE. No kernel or tweaks on the distro.
I run the game at low details, Resolution Scale at 50%, V-Sync off, fps capped at 60, View distance on High, Textures on High, Shadows on Medium, Reflection on Medium. Native 1080p resolution, no FSR and Antialiasing TAA.

Overall very comparable to the native windows experience, pretty happy playing it on linux, sometimes better performance but slower to start
Lumen software RT reflections are kinda broken on Linux it seems compared to windows... reflections take a lifetime to load and render, and most of the time look shit :(
Steam didn't transfer my windows save across to fedora, but that's possibly my fault, got it back in the end
Similar to windows in terms of chugging in outdoors areas, additional chugging in graphics menu as compared to windows
- Decent light modding support, chucked a few armour remodels in without a hitch thus far, look forward to more in-depth modding in the future :)
