Not a long game and you should play Resident Evil 2 first. RE3's first part is before RE2 and after the middle is after RE2.
I Iike to have a L3 as the run button. Also turned on Gyro (as joystick) with a low sensibility for micro ajustments in my aiming. Also lowered the joypad sensibility a bit for better aiming.
I played mostly at 40 fps to have a stable 40. But this game when you get to the second to last boss, you have to be above 45 fps or the boss will just not stop running. You can play this game with fps disabled or just cap it between 45 and 50 perhaps for a more stable run.
In game settings, I left everything as default except FidelityFX Super Resolution 1.0, which I turned off. No need for scaling here. You get a sharper and clear image.
In the Steam Deck Performance tab: Allow Tearing: On, TDP Limit: Off, Manual GPU Limit: 1600 mhz. Now the fps is the tricky part, for a stable perfect fps, cap it at 40 but like said there is a bug with the boss before the last one where he will not stop running around the area. You need to be above 45 fps. I just disable fps toggle and played to the end. This last part ran very well. It's in the city the fps can go up and down.

Only the first cutscene is out-of-sync, which is due to it being pre-rendered.
I would recommend binding the D-Pad to the back buttons, just to make swapping weapons a bit easier.

I changed the game's default graphics settings and capped it at 60 Hz for a smooth experience:
- Disabled FSR 1.0 upscaling (The Steam Deck OLED is capable of plaything the game at native resolution)
- Anti-aliasing: FXAA+TAA
- Texture: High (4 GB), Filter Quality: High (ANISO x4)
- Mesh Quality: Medium
- Shadow Quality: Medium, Shadow Cache: On
- Screen Space Reflections: On
- Subsurface Scattering: On
- Volumetric Light Quality: Medium
- Particle Lighting Quality: High
- Ambient Occlusion: FidelityFX CACAO
- Bloom: On, Motion Blur: Off, Depth of Field: On
The game complains about graphics memory, but this can be ignored, as I played through the entire game in long sessions with these settings without any problems or crashes.

Great experience, played it half and half on Deck and Desktop. Rolled credits on Deck. Cloud saves work perfectly.
Low/Medium settings with High (0.5gb) textures. Runs at 60fps almost all of the time. No FSR used (FSR 1 looks really bad at this res) and normal rendering. 12-15w in most instances. On Steam Deck OLED this game has perfect HDR that adds maybe half a watt.
The map become a little hard to decipher and glitches a little once zoomed out but zoomed in its completely legible.

Had to use Proton GE due to Codec issue

11wt, 44fps cap in portable mode
crashes after a while
beat the RE2 with 69 saves!!! Since it will crash in any minute i just closed the game and run it again in order to reset the countdown before the crash. RE3 have the same issue
Audio seemed to get out of sync during cutscenes
runs smoothly at 60 on balanced graphics preset, possible it would struggle in more demanding areas like boss fights and outdoor zombie bits
played a bit of the hospital section on my deck, mostly filing this since there aren't any other reports as i didn't truly test the game. given how strong the RE engine is and that the 2 remake is verified, i struggle to imagine this game would ever be unplayable, though graphics settings may have be fiddled with until it runs well in all encounters and areas. it appeared i would have a good 2-2.5 hours on battery on the settings i ran it at, though as i wasn't truly testing i didn't really watch/check it. runs well! strange its marked as unsupported!
Final boss glitches if below 60 FPS
Played through the whole game on deck, capped at 45 FPS on medium settings.
Please note that you will have to uncap your framerate at the final boss, otherwise it glitches.

steam menu settings set refresh to 60 set frame limit to 30 everything else was stock. Got 3 1/2 hours of game time with these settings.
works out the box.
Set refresh rate to 40Hz. TDP limite to 13w. GPU Clock to 1500Mhz.
Works fine, has high settings. Text is ok but gets aliased when ya use fsr. 2 hrs and 15m without any changes
See concludding notes. 3 hours and 25 minutes
not the clearest text, especially using fsr for batterylife improvement.
one crash when jumping through different resolutions to try and find a sweet spot for fsr.
3 hours and 30m steam settings: set refresh rate to 45hz. half rate shading looked awful, dont bother. set fsr to on and sharpness to 2 In-game settings: set to dx11 fullscreen 960x540 normal rendering 110% image quality 60hz refresh rate v-sync on AA: Fxaa texture quality to high texture filter: high (ansio x2) mesh quality: meduim shadows: meduim shadow cache: on screen space: on subsurface scattering: off volumetric lighting waulity: medium particle lighting: low Ambient occlusion: ssao bloom: on lens flare: on motion blur: off DOF: off Lens distortion: on in game fsr: off
