[SystemSettings]

; Engine

r.ShaderPipelineCache.Enabled=1
r.ShaderPipelineCache.LogPSO=0	; disable PSO logging (only useful during development)
r.bForceCPUAccessToGPUSkinVerts=1	; offloads to the processor reducing load on the video card
r.GTSyncType=1
r.OneFrameThreadLag=1			; improves FPS at expense of input lag
r.FinishCurrentFrame=0			; don't wait for the current frame
r.UseVSync=0				; disable if you have variable refresh rate (VRR)
r.D3D12.UseAllowTearing=1		; allow tearing when you have VRR
r.TextureStreaming=1			; don't try to load all textures into VRAM
r.Streaming.LimitPoolSizeToVRAM=1	; don't try to use system memory for anything important

; Shadows

r.SSGI.Enable=1				; enables global illumination that replaces ambient occlusion and regular shadows
r.SSGI.HalfRes=1				; 10fps better and i can't see any difference!
r.SSGI.Quality=4				; (range 1 to 4) 2 is a good balance if you need more fps
r.ShadowQuality=5				; seems to do nothing when using SSGI
r.DynamicShadows=1			; seems to do nothing when using SSGI
r.Shadow.CSM.MaxCascades=5		; how many layers of shadows can be added
r.Shadow.CSM.TransitionScale=2	; blurs the cascaded shadows. without this shadow lines cut across the screen (nasty)
r.Shadow.MaxCSMResolution=2048	; resolution of cascade shadows. 4096 works well as well
r.Shadow.MinResolution=512		; default is 32
r.Shadow.MaxResolution=2048		; i've returned this to 2048 because lower causes flickering in rare circumstances
r.Shadow.RadiusThreshold=0.03		; reduces shadow flickering in some situations
r.Shadow.DistanceScale=1		; higher causes weird problems in some areas
r.Shadow.Preshadows=1			; reduces shadow pop-in
r.Shadow.MaxNumSpotShadowCacheUpdatesPerFrame=1		; updates shadows every frame (for smooth sun shadows moving across the world)
r.Shadow.MaxNumPointShadowCacheUpdatesPerFrame=1	; updates shadows every frame (for smooth sun shadows moving across the world)
r.DynamicShadows=1			; doesn't appear to be used with SSGI (not that i've found yet)... testing
r.ContactShadows=1			; this is required for plants and people shadows
r.WLightProbesContactShadows.HalfRes=0			; renders contact shadows at half res, saves several fps and stops some shadows from flickering, but unfortunately makes grass blurry
r.AllowLandscapeShadows=1		; required for landscape self-shadowing

; LoD and Textures

r.MaxAnisotropy=16			; i can't see much difference between 8 and 16 in this game
r.VT.MaxAnisotropy=4			; default is 8 but lowering slightly seems to reduce noticable texture tiling (while still looking good)
r.ViewDistanceScale=5			; higher doesn't seem to make any difference
r.LODFadeTime=3				; default is 0.25s causes sudden pop-ins on the few remaining pop-ins. increasing makes things fade in smoothly
r.Shadow.FadeExponent=3			; default is 0.25s causes sudden pop-ins on the few remaining pop-ins. increasing makes things fade in smoothly
r.Decal.FadeDurationScale=3		; default is 0.25s causes sudden pop-ins on the few remaining pop-ins. increasing makes things fade in smoothly
r.AOViewFadeDistanceScale=3		; default is 0.25s causes sudden pop-ins on the few remaining pop-ins. increasing makes things fade in smoothly
r.LightMaxDrawDistanceScale=5		; increase draw distance of light cast by light sources. 5 is max
r.MaterialQualityLevel=3		; enables layering of textures
r.DetailMode=2				; increases details of textures/texture layering

; Environment

r.VolumetricFog=1
r.VolumetricFog.DepthDistributionScale=32			; effectively the size of discreet bits of fog
r.VolumetricFog.InjectShadowedLightsSeparately=1	; this enables shadows to interrupt fog which looks amazing
r.VolumetricFog.HistoryWeight=0.97				; stops fog flickering and makes it move smoothly like real fog, smoke, and dust
r.VolumetricFog.TemporalReprojection=1	; testing
foliage.LODDistanceScale=10			; foliage visibility range. max is 5
grass.DensityScale=1.4				; slightly increase grass density (default 1.25)

; Reflections

r.ReflectionCaptureResolution=512	; default is 128. this makes a big quality improvement with little fps difference. 1024 is nice too
r.Reflections.Denoiser=0		; disabling because i can't see a difference
r.SSR.Quality=4				; higher quality improves shadows on reflections significantly
r.SSR.Temporal=0				; all except one lake looks better with this off
r.SSR.MaxRoughness=-1			; balance of screenspace reflection graininess vs detail
r.TranslucencyVolumeBlur=1
r.Water.SingleLayer.SSRTAA=1		; more ralistic water
r.RefractionQuality=2			; i can't see a difference between 3 and 2 so left it at 2

; Subsurface Scattering on Skin

r.SSS.Scale=3		; intensity of screenspace subsurface scattering for skin on characters. 0 is off >1 is accepted
r.SSS.Checkerboard=1	; uses half the pixels to calculate SS. looks terrible if this is turned off, i think when set to 0 it's broken
r.SSS.HalfRes=1		; render screenspace subsurface scattering on characters at half-res. minimal fps difference so left on
r.SSS.Filter=0		; disabling because i can't see a difference during cut scenes

; Lighting

r.ParticleLightQuality=2
r.EyeAdaptationQuality=2					; not a huge difference in fps but nicer quality
r.EyeAdaptation.ExponentialTransitionDistance=6		; how long it takes your eyes to adapt (range 0-10)

; Post Processing

r.PostProcessAAQuality=4		; set to 0 if using DLAA and DLSS. this DOES make all textures a little blurrier
r.DepthOfFieldQuality=4			; 5 is max but is a bit "too much"
r.BloomQuality=5				; generally improves tone rendering. 5 is a bit too crazy bloom
r.Tonemapper.GrainQuantization=1	; film-grain (which is subtle in this engine). 0 to disable
r.DefaultFeature.AmbientOcclusion=0	; not used with SSGI but still costs fps, so disabling. this does not disable ray traced AO
r.AmbientOcclusionLevels=2		; makes windows and lights look nicer (somehow works with ambient occlusion off!)
r.AmbientOcclusion.Method=5		; makes windows and lights look nicer (somehow works with ambient occlusion off!)
r.SkylightIntensityMultiplier=0.7	; adjusts the light at ground level due to sky / time of day. fixes SUPER bright sun

[/Script/Engine.StreamingSettings]
r.Streaming.Boost=1			; global boost affecting the "wanted" resolution of textures
r.Streaming.MinMipForSplitRequest=1	; prioritises loading visible mips over non-visible

[/Script/Engine.RendererSettings]
r.RayTracing.AmbientOcclusion.Intensity=1.3	; darkens the shadows cas by RT AO
r.RayTracing.Reflections.DirectLighting=0		; disables reflections directly from light sources, which have the most problems and often look out of place
r.RayTracing.Reflections.MaxRayDistance=2000	; stops considering reflections after the ray has traveled this distance
r.RayTracing.Reflections.ScreenPercentage=51	; downscales the screen for the RT reflections, slightly off a multiple to help add diffusion/blur
r.RayTracing.Reflections.SamplesPerPixel=1	; how many reflection samples to consider per pixel. no difference between 1 and higher
r.RayTracing.Reflections.MaxRoughness=0.6		; how shiny everything looks. 0.3 less things will have reflection, 0.6 is default, 0.8 is nice but too shiny
r.RayTracing.Reflections.MaxBounces=1		; how many times a ray can bounce off objects
r.RayTracing.Reflections.Shadows=0			; don't try and reflect shadows, saves fps
r.RayTracing.Reflections.HeightFog=1		; put a maximum height cap on RT. can help fps
r.Reflections.Denoiser=2				; options are 1 or 2, but 100 seems to help in a lot of situations. pretty broken in this game
r.RayTracing.Reflections.Hybrid=1			; blends RT reflections with screenspace reflections, which tends to yield a better result (imo)

; Colour System

r.LightFunctionQuality=3
r.HighQualityLightMaps=1
r.SceneColorFormat=2		; above 2 makes no discernable difference
r.Color.Min=0.00			; represents 'black'
r.Color.Mid=0.80			; change the default colour curve (default is 0.5 i think)
r.Color.Max=1.05			; chahnge 'white' to give better colour range. 1.1 works well as well
r.TonemapperGamma=1.30		; increase gamma so everything has more contrast and more cohesive
r.Tonemapper.Sharpen=2.4	; sharpens image. (you won't need DLSS/FSR2.0 sharpening.) with RT enabled, increasing this to 2.0 to 2.8 works well
r.TonemapperFilm=1		; enable more accurate (filmic) colour gradients
r.Tonemapper.Quality=2		; 2 is much more integrated exposures between objects

; Features Enable/Disable

r.MotionBlurQuality=0			; 0 disables motion blur
r.DisableDistortion=0			; used for spell distortion. however, disabling saves a full screen buffer (which is a lot of memory at high res)
r.DefaultFeature.LensFlare=0		; disables lens flare (i don't think it's used anyway)
r.LensFlareQuality=0			; as above
r.SceneColorFringeQuality=0		; disables chromatic aberration
r.Fog=1					; set to 0 to disable all fog
