Decided to test the various console commands, and here’s what I found that had any effect:
r.Upscale.Quality 0 = Integer upscaling (set resolution to 1/2, e.g, for 2560x1440, set game resolution to 1280x720)
r.Upscale.Quality 1 = Blurry as hell
r.Upscale.Quality 2 = Blurry as hell
r.Upscale.Quality 3 = Blurry as hell
r.Upscale.Quality 4 = Blurry as hell
r.Upscale.Quality 5 = Brighter than 0, odd sharpening/blur filter
r.AmbientOcclusionLevels 3 = Default
r.AmbientOcclusionLevels 1 = Darker
r.AmbientOcclusionMaxQuality 26 = Default, no difference when higher, turns AO off when lower
r.BloomQuality 0 = Off
r.BloomQuality 2 = What’s the point
r.BloomQuality 3 = Even less bloom
r.BloomQuality 4 = Less bloom
r.BloomQuality 5 = Default
r.DefaultFeature.AntiAliasing 0 = None
r.DefaultFeature.AntiAliasing 1 = FXAA
r.DefaultFeature.AntiAliasing 2 = TAA
r.Shadows.MaxResolution 2048 = Default
r.Shadows.MaxResolution 4096 = More detail
r.Shadow.Quality 0 = Off
r.Shadow.Quality 1 = No blurring
r.Shadow.Quality 2 = Slight blurring
r.Shadow.Quality 3 = Moderate blurring
r.Shadow.Quality 4 = Heavy blurring (default)
r.Shadow.Quality 5 = Same appearance as 4
r.ViewDistanceScale 1.2 = Default
r.ViewDistanceScale 2.0 = Nice
r.ViewDistanceScale 2.3 = Max?
Edit: You can add these settings to startup, so you don’t have to type them in manually every time. Navigate to Conan Exiles\ConanSandbox\Saved\Config\WindowsNoEditor and open Engine.ini. Here is mine, for reference:
