Game installs but doesn't run. Will often immediately crash after launch. Otherwise locks up PC on loading screen; requiring a hard reboot.
[Imporant to note: I use Proton Experimental as the default for my entire library] Game installs but doesn't run. Sometimes won't launch at all; Steam will say it's opening the game then just immediately close it. When it does launch it will lock up the entire PC on the first Unity loading image; requires a forced hard reboot to regain use of the PC.
I have found no workaround.

Cannot launch&play using proton experimental I can start the game using native bug the menu and game is so laggy, unplayable
Does not work
+fps_max 0
OOTB unable to set resolution above 60Hz, fixed by forcing Proton Experimental.

The native version did not work at all for me as it crashed too often. Switching to Proton 9.2 fixed everything.
It crashed 2-3 times over the course of 40 hours. Nothing major.
I've completed the game using Proton 9.0 without issues
Native just works
Flawless

3-4 hours battery life with screen locked to 40 FPS and TDP set to 10 Watts
Playing the Epic Game Store version and the first time you launch the game needs to be in desktop mode or else you'll be stuck on the loading screen
Really fun stealth game and the mission based structure makes it a great fit for steam deck
Crashes occassionally after many hours of playing.
Runs flawlessly.
Works great
OOTB
works
works out of the box.
Apart from the FPS Limiter bug, which will be soon on the main branch of proton, this is a Verified Steam Deck game and it runs flawlessly.
Issue
Currently, there is a bug with the FPS limiter. The GameScope integrated limiter didn't apply at first nor the VSYNC in the game settings. This resulted in high FPS (100-110) in game and a lot of wasted battery life due to this.
Fix
From your library go to the game's page. Settings button, and then properties. Under the Compatibility section tick "Force the use of a specific Steam Play compatibility tool" and then choose Proton Experimental in the dropdown. The game will re-download and re-install itself after this and the FPS limiter now works like a charm. Enjoy!
Alternative Fix
I saw another report that suggested limiting the TDP to around 7 watts and that worked but it results in non-consistent Framerate. And you have to switch it on just for this game which is a bit annoying.
This report will become obsolete once the next Stable Proton release includes the fix for the FPS limiter.

VSync is enabled by default but FPS stays uncapped regardless, making the GPU run very hot and eating through battery life.
This can be mitigated by using Gamescope Thermal Power (TDP) Limit. Setting it to 7 Watts yields framerates around 50-70fps and improves GPU temperature and battery life a lot.
Desktop mode used to install native Linux version with GOG shell installer.
Missing dependencies have to be installed manually with pacman
:
- If first-time pacman usage:
passwd
sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate archlinux
- Install missing dependencies
sudo pacman -S lib32-libxcursor lib32-libxrandr
- Optionally set SteamOS back to read-only
sudo steamos-readonly enable
Shortcut to /home/deck/GOG Games/Shadow Tactics Blades of the Shogun/start.sh
added manually to be able to run it from Gaming mode.
Native resolution supported and detected, full controller support.
Native has a few problems, Proton runs perfectly out of the box
- Performance on Proton is better than Native, with less stutters while moving the camera as well as higher framerates.
- Native also couldn't recognize the right trigger on my Logitech F710, while it worked perfectly on Proton.
Game is native on Linux, no point in using Proton to play the Windows version. Game also runs butter smooth.

Lowest possible settings. Around 30-40 FPS with some 50 FPS peaks, CPU load 80%, GPU load 60-80%, Requested VRAM: under 800MB
Update of my previous report.

Freezes on exit to desktop. I don't know why... but overall, works well.


Runs smoothly with no problems
