60 fps cap, Allow Tearing and 7 TDP
In game: Everything on the highest and Anti-Aliasing 8X

You just connect a second controller and start the Splitscreen. On the Steam Deck display it's a bit difficult, but on a external monitor it runs fine
I don't know, why valve listed the game as not compatible. The game runs great on the deck.

Absolutely perfect.
Same as. Perfect.

splitscreen coop works perfectly
also a good candidate to implement gyro controls if you want

First story FMV doesn't play correctly. Skip to avoid freezing the game.
Split screen with a bluetooth controller works as expected

wmp11 (Windows Media Player 11)
Install with protontricks
FMV's weren't working without the Windows Media Player 11 component installed
While not required installing Maluc's Patch (I haven't tried Rick's but it should work) is not a bad idea. And making sure the Launch Command is used. Installing Windows Media Player 11 through protontricks should help if FMVs aren't working. Launch options aren't needed if not using one of the patches.

Sometimes joining players that uses mods? Might crash the game. Overall it is playable start to finish with whoever the player is.
Tried with External Controller or With Steam link (if you want to play it that way) it works really well.

Game runs at solid 60fps on the Steam Deck. I switched to controller layout from community (the first one on the list) I would highly recommend this game. It runs great and should be verified IMHO.

Controller became unresponsive amid game on couch coop with 2 controllers connected.
Game pad became unresposive from time to time on dual controller setup. Closing the game and reopening it solved it.
Game playable at 1080p on co-op with the steamdock.
There was a fix crash when fighting one of the boss, but it sems to happen on Windows as well, changed the resolution from 1080p to 900p (I played the game docked on my TV) RE5 Steam version crashing at end of 5-1.
Bound L3 to both L4 and L5 to increase comfort, also made holding L2 the gyro enable button
When pressing the Steam button, there appeared to be a second window open but attempting to switch to it did nothing, nor did it cause any issues at all
Didn't have a second person to thoroughly test but I connected a Switch Pro Controller and it seemed to work just fine, one player using the Steam Deck Controls and another using the Pro Controller, in both the main game and the Mercenaries mode.
It seemed to just work for me. Played through the whole game. I vaguely remember a single pre-rendered cutscene at the start of the game not playing properly, but apparently I never once switched to Proton-GE so it must have fixed itself.
Can't go through the Capcom and Dolby logo, tried every proton versions and fixs, it just don't work
Any of the fixes don't work, can't pass the Capcom and Dolby logo
go on with Windows maybe

The title screen says "press any key" to continue, but if you're using the default gamepad layout, only the Start button works.
Occasional brief hitching when changing areas or entering/exiting buildings.
works right out of the box no issues
get a pal for the coop, the game improves drastically that way
Funziona perfettamente senza fare alcuna mdifica. La modalitá online non è più disponibile, ma il multiplayer locale funziona ancora.
Forse è possibile giocare online su windows tramite meshnet di nord vpn e la modalità multiplayer LAN
Game fails to get past the Capcom Logo with default Proton. Works fine when swapped to Proton Hotfix.
Played with someone using a Windows PC with the latest update. Worked perfectly fine, no issues.
Game fails to get past the Capcom Logo with default Proton. Works fine when swapped to Proton Hotfix. Played 3 hours online with a friend, had 0 issues after the fact. Had to reinstall the game after updating due to previously installing the Fixes mod.
Games for windows was removed so there is need to do any tinkering, all works out of the box
https://steamcommunity.com/sharedfiles/filedetails/?id=864823595 Maluc's Resident Evil 5 Fix
Game does not start without applying the mentioned fix, mainly for bypassing Games For Windows Live. After that the game is an enjoyable experience at stable 60 fps throughout the game. Gyro controls seem to suit the game well.
If you're comfortable opening up Steam install directories and copies some files over, its easy to get running.
DXVK_ASYNC=1 WINEDDLOVERRIDES="xlive.dll=n,b" %command%
I couldn't get Resident Evil 5 fixes to work without bypassing Games for Windows Live separately (despite claims by its install page). I did get it working though. Here are the steps I follow.
First, download Resident Evil 5 fixes. Extract and copy into the game's install directory.
Next, bypass Games for Windows Live by copying xlive.dll (easy to find in Google) into the game's install directory.
Then, open the game's properties in Steam and add this to your command line:
DXVK_ASYNC=1 WINEDDLOVERRIDES="xlive.dll=n,b" %command%
Finally, set compatability to Proton Experimental.
I tried some of the instructions from other reports, but the game would not start even though Steam showed it as running. It wasn't until I used all the settings noted above that it started to work. But now it runs great!
DXVK_ASYNC=1 WINEDDLOVERRIDES="xlive.dll=n,b" %command%
Use the "Maluc's Resident Evil 5 Fix" https://steamcommunity.com/sharedfiles/filedetails/?id=864823595
No issues with random person joining for coop
Easy to get running well after a few steps:
- Install the game
- Before launching, copy and paste files in game folder from "Maluc's Resident Evil 5 Fix". Be sure to overwrite what was already existing.
- Set compatibility to GE-Proton7-27 (If you don't have GE-Proton7-27, lookup how to install GE-Proton on Steam Deck)
- Add DXVK_ASYNC=1 WINEDDLOVERRIDES="xlive.dll=n,b" %command% to Launch Options
- Launch game from desktop mode and confirm it boots
- Switch to Gaming mode and run game
RE5 runs extremely well on the Steam Deck after I followed these steps. One of my all time favorites so I felt I had to share how I was able to get it running. Enjoy!

Download xlive.dll from here https://www.dll-files.com/xlive.dll.html and place it in the game folder

DXVK_ASYNC=1 WINEDLLOVERRIDES="xlive.dll=n,b" %command%
I was using ps4 controller and that worked fine, but you want to use mouse and keyboard, you need to start this game from the desktop mode.
Joining my friends game was possible from the join menu within the game.
Game needs to be started from the desktop mode, and initial launch can take multiple minutes to appear, but after that you can play it from the game view, if you don't reboot your steam deck.
Mouse and keyboard seems to be working only from desktop mode.
I played multiple hours with my friend online and we had no issues. At some point I did disconnect, but that was non game releated wlan issue.
Performance was great while in game mode and connected to my display, desktop mode did try to run the game in 1440p and that caused quote lot of tearing, but another that that, it still was snappy.
Games For Windows Live is a installation prerequisite, it doesnt exist anymore as a download. Had to download an external custom package to bypass this
GFWL is a killer prerequisite to a lot of 2008-2010 games from Capcom. It really disables their games completely, dunno what you can do from that end.
Ultimate patch to remove GFWL and replacing startup .wmvs to empty files
Will not launch without tweaks but they're fairly simply to do and work great. Runs at a consistent 60fps on high settings, 16:10 works out of the box. Only minor thing is occasional stutter when shooting, likely shader caching as it smooths out over time
