To start;

You've probably noticed sprites for characters looking grainy and blurry when they animate. This is due to Unreal Engine 4's temporal AA not being suited for sprite-based games. Here you'll find two fixes for this problem.

First, find and open the game's Engine.ini file. On Windows, this can be found in

%USERPROFILE%\Documents\My Games\TRIANGLE_STRATEGY\Steam\Config\WindowsNoEditor

On Linux or the Steam Deck, This folder structure with the file should be in

/run/media/mmcblk0p1/compatdata/1850510/pfx/drive_c/users/steamuser/Documents/My Games/TRIANGLE_STRATEGY/Steam/Config/WindowsNoEditor

Once you've opened Engine.ini, paste one of the following sets of variables at the bottom and save the file. Don't mix these two fixes together, or the map screen will look broken.

Performance-intensive fix

[SystemSettings] r.ScreenPercentage=150 r.TemporalAASamples=4 r.TemporalAACurrentFrameWeight=0.4 r.TemporalAAFilterSize=0.7 r.ToneMapper.Sharpen=0.5

You can replace the "150" number with any percentage scaling you want. At 150, that means the game renders at 150% of your monitor's resolution. Setting it between 125 to 200 is reccommended, with higher numbers having a bigger performance impact.

Low-performance fix

[SystemSettings] r.TemporalAA.Algorithm=1 r.TemporalAA.Upsampling=1 r.ToneMapper.Sharpen=0.5

This is recommended for use on Steam Deck, by my own testing.

neat all i've done to get around this is set post processing and AA down to medium i'll have to see how this works eventually but yeah the defaults are awful.

You can copy the path to the folder that's in the guide into the address bar at the top of File Explorer, and that will take you directly to it. The one that starts with %USERPROFILE%.

Thanks, trying to find the Engine.ini file but it's not even showing up when I try a search

Dinjoralo [author] 14 Apr, 2023 @ 6:34pm

That is correct, yes.

I don't do this sorta thing a lot so wanna be clear, paste everything including [SystemSettings] correct?

I'm quite new to Steam Deck and was trying to get to the Engine.ini. is it only accessible in Desktop mode?

For microSD on Steam Deck the path is:
/run/media/mmcblk0p1/compatdata/1850510/pfx/drive_c/users/steamuser/Documents/My Games/TRIANGLE_STRATEGY/Steam/Config/WindowsNoEditor
