Overall run the Game in fullscreen. Dont cap the framerate and dont use v-synch.
Everytime u start the Game make sure to launch via your steam library and choose to launch with directx11.

Next Step: Navigate to your Outriders Config Data
-> AppData -> Local -> Madness -> Saved -> Config -> WindowsNoEditor -> Engine.ini

Open the Engine.ini and complete it using the following:

[SystemSettings]
r.DefaultFeature.AntiAliasing=2
r.TemporalAACurrentFrameWeight=0
r.BlurGBuffer=0
r.DefaultFeature.Bloom=0
r.EyeAdaptationQuality=0
r.FastBlurThreshold=0
r.FullScreenMode=0
r.LensFlareQuality=0
r.MaxAnisotropy=0
r.MotionBlur.Max=0
r.MotionBlurQuality=0
r.SceneColorFringe.Max=0
r.SceneColorFringeQuality=0
r.Streaming.FullyLoadUsedTextures=1
r.Streaming.HLODStrategy=2
r.Tonemapper.GrainQuantization=0
r.Tonemapper.Quality=0

[/script/engine.inputsettings]
bEnableMouseSmoothing=False


Close and save it.

The First Line is about Antialiasing.
For turning off set it to 0. For FXAA set it to 1. TAA is 2 and MSAA is 3.
I tried everything and in my opinion the best looking one is TAA (2).
The second Line (r.TemporalAACurrentFrameWeight=0)
makes the TAA looking better. If u chose one of the others .. u dont need that line.
But i totally recommend using TAA :)

The last line is about the mouse acceleration. In game u may just set it to 1 minimum.
That sucks a lot.
To feel better with aiming, most people prefer to set this to 0 for better mouse handling.
And so do i. Make your choice.

Have fun and enjoy!
