Runs well as-is, can run at 40 with High settings but can chug. Medium or Low may be better. Tinkering may allow for better consistency.
Config File Location:
From PCGamingWiki:
- Steam Play (Linux): /steamapps/compatdata/989440/pfx/ The GameUserSettings.ini file can be found from there in:
- /drive_c/users/steamuser/appdata/local/PhantomAbyss/Saved/Config/WindowsNoEditor/
Config file explanation:
The config contains settings to adjust the quality of the game's graphics settings without fiddling with the game's presets. This may be useful to those looking for a more consistent framerate. There was also a line for bUseDynamicResolution, turning it on did not seem to cause any negative impact, so it can't hurt to try.
Altered Steam Deck profile settings:
- TDP Limit - On > Off
- Manual GPU Clock Control - 1100MHz > 900MHz
Under heavy stress situations (i.e. room full of traps with phantoms running around opening chests), the performance dips ranging from mild to significant. Further testing at 40 Max FPS resulted in a framerate as low as 24-26 while in said situation on High preset.
Concluding Notes
- From the previous report, I found that my former Steam Deck settings wasn't sufficient to keep it consistent when met with the game at its heaviest.
- Consulting PCGamingWiki yielded a way to edit the graphics settings at a more granular level that the devs have not yet implemented, at the time of publishing, in-game. Initial testing seems positive and I am certain there's a good way to get a compromise between graphical fidelity, framerate, and battery life as a whole.
- All in all, the game is perfectly playable on the Steam Deck as-is. Tinkering is advised only if performance issues get a bit too much to handle and you desire your framerates to be much more consistent.
Steam Deck Per-Game Profile Settings
- Refresh Rate - 40Hz
- Half Rate Shading - On
- Thermal Power (TDP) Limit - On @ 7-8W
- Manual GPU Clock Control - On @ 1100MHz
- Scaling Filter - FSR
In-Game Settings
- Display Mode - Windowed
- FPS Cap - Set to Refresh Rate (In my case: 40 FPS)
- Graphics Preset - Low to Medium will yield better battery life results. High may be preferable if you do not wish to sacrifice graphical fidelity.
- Other options are as to-taste as it gets. (Highly recommend turning off Landing camera rotation, even if this is irrelevant to the report)
Some tooltips can be a little hard to read, especially when picking out a whip from the entrance.
Mild slow-down, particularly in moments where there are a lot of objects on-screen (i.e. at the start with phantoms numbering in the high double-digits/low triple-digits).
Concluding Notes
You may need to drop the graphics preset to Low or Medium to achieve a more consistent 60 FPS but locking at 40 at High will do the trick nicely. You could potentially push Epic at 40 if you wish.
Patch broke the game
With the new patch added today, I get a popup saying, "DX12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument." Worked flawlessly yesterday with zero configuration. Literally cannot boot the game anymore.
Very playable experience.
Inputs are a bit inconsistent even at high framerates.
I'd say the game runs at ~ 70% the framerate of the windows version.
You need to add -dx11 to launch options
Works perfectly under Proton 6.3-5
Launches to a black screen. Fixed by adding -dx11 launch option.
Didn't work with Proton Experimental
6.3-4 and -dx11 was okay
Seems to work almost perfectly so far, except for minor issues with mouse sensitivity.
The mouse sensitivity seems to change slightly sometimes; unsure of the cause. Possibly framerate related.
Works great
Phantoms work as expected and I was able to play 20+ levels. Experienced some framerate slowdowns but I can't confirm that it's due to Proton or my setup, only occurred in high density areas.
After the workaround to launch, FPS was a little choppy in tutorial but 60+ in the temples.
Required adding -dx11to the Launch Options, installing and using Proton-6.10-GE-1, and disabling Shader Pre-Caching (if you have it enabled)
Worked great out of the box!
Lots of fun. Seems to run just fine on Manjaro.
Runs straight out of the box. No issues thus far. Will update if I run into any problems.
There may be a problem with resolution selection. Selecting different resolutions doesn't appear to change the resolution. Windowed Fullscreen does not offer the full selection of resolutions. Fullscreen doesn't swap to that resolution.
The game came out today. I've only tried the tutorial, and there haven't been any issues so far. Visuals seem good. Audio seems fine. Menus are smooth. Only tried mouse + keyboard, but will try with a controller. Will update as I continue playing.
