Steam Deck9 Reports
Changed audio settings to enable OpenAL Soft
Significantly reduced TDP and GPU clock.
Some crackling with default OpenAL Soft settings. Fixed by reducing audio frequency to 44100
Thief: Gold used to run flawlessly, but a recent SteamOS update seems to have introduced a major graphical issue when any Steam overlay elements are invoked. The game and the overlay fight and cause rapid white flickering over the whole screen. This makes it impossible to make adjustments to the power settings as the '...' Steam Deck menu can not be seen. Also, as the control layout I use implements an on-screen menu wheel for weapon selection, this flickering makes it incredibly difficult to use. I've tried using Proton Experimental, Proton 9, 7, and 3 and have gotten the same results so I can only assume this is a display driver issue introduced in SteamOS 3.6.
be sure to install TFix, even if you disable gameplay changes, its almsot mandatory to get the game running properly
i made the config
reduced watt and GPU speed to minimum, doesnt seem to affect performace, otherwise the game seemed to consume more battery than expected
some slight crackling, dunno why
without TFix the game performance is abyssmal
download TFix 1.27, go to desktop mode, add the installer as a non-steam game (remember to set the proton compatibility layer in properties), run it, patch your installation of Thief and then you will be able to enjoy the game
TFix drastically improves performace and adds widescreen options, theres some OPTIONAL gameplay changes TFix introduces, but you can disable those in the installer so you get a mostly vanilla experience
i used Proton-6.1-GE-2 to run the TFix installer
Install TFix
Works amazing once you install TFix (link). Use Lite or the one with mods, doesn't matter, I used the full installer to add some quality of life mods.
You could use lutris to install it, but I went with a different route. Download the TFix installer .exe, add it as a non steam program, then enable compatability and run it with Proton experiemental. Then launch the TFix installer through steam, go through the installation wizard as you would regularly! The correct install path for the steam deck is:
z:\home\deck\.steam\steam\steamapps\common\thief_gold\
Once installed you can remove the .exe from steam, then just launch the game and enjoy! Recommended community layout works great on the deck
When start playing there are no fps you can't interact with anything and you even can't go back to the main menu
Used Lutris to add Tfix v1.27 and HDmod v1.2 by adding them as a manual game with wine in order to run the patches. After loading up the game and changing a few settings in the in-game control settings to get strafing working. The game runs fantastic. No additional steps were needed.
After applying Tfix and HDMod the Steam Decks controls started working fine. I just changed the settings to allow for strafing and backwards movement.
Out of the box from steam, it definitely runs terrible.
Install TFix Light
Thief with TFix Light (not the full TFix as far as I've seen) has working joystick support for movement. Set the left stick to be used as joystick instead of a keyboard mapping for a very smooth experience. Everything else needs to be mapped to keyboard and mouse, still.
Locked 30 FPS
Out of the box it doesn't really work as the game will be extremly slow and stuttery. TFix is a must, at least on Steam Deck.
Tfix is mandatory to make this playable. I use Tfix Lite
Install Tfix and it will be perfectly playable.
