How to fully disable anti-aliasing in Gears of War 4 on PC?

Gears of War 4 has configuration files that can be edited in the following directory:

%LOCALAPPDATA%PackagesMicrosoft.SpartaUWP_8wekyb3d8bbweLocalStateGearGameSavedConfigUWP

There are some solutions for your problem offered in this Steam thread:

• One of these files is GameUserSettings.ini, in which you can turn off anti-aliasing by changing the value of sg.AntiAliasingQuality= to 0.

  Then, in another file called Scalability.ini, make sure that under [AntiAliasingQuality@0], you have r.PostProcessAAQuality=0

• Another user mentions to only change Scalability.ini, and to edit in the following values:

  [PostProcessQuality@3] r.MotionBlurQuality=0 r.SceneColorFringeQuality=0 r.PostProcessAAQuality=0

Mentions of it ruining the visuals are abundant, though, so you probably need to do a lot of tweaking.

• Another option is to force AA off through nVidia Settings or nVidia Inspector if you have an nVidia GPU, or through AMD Radeon Settings if you have Radeon GPU.

If the problem you have with Anti-Aliasing is the strain it puts on your eyes, or you just don't like it aesthetically, you might be interested in turning off Chromatic Aberration and Motion Blur as well, which can be done by editing the values as posted here.

As mentioned in that same post, be sure to change the properties of the edited files to 'Read-only'.

^{* I'm not sure about this, but the 'Microsoft.SpartaUWP_8wekyb3d8bbwe' folder might have a slightly different name. If anyone finds out, please post a comment and I'll edit it in.}
