S.T.A.L.K.E.R. 2 Heart of Chornobyl

Overview

U+ for Stalker 2 significantly reduces the amount of noise and improves fidelity while maintaining performance. It is also a long running game of whack-a-patch every time they patch the game.

Setting	Options	Keybind	Description
AutoApplyConfig	off,on		automatically reload settings when config file changes
BetterReflectionSDFs	game,off,on		Increases the resolution of meshes in global software lumen space, most noticeable in reflections
Bloom	game/0-3	CTRL+F3	Bloom intensity (0.0 = off, 1.0 = default, 2.0 = double, game = use game default)
ChromaticAberration	game,off,on		Recommend disabling in most games as it often just blurs the image for no benefit
ColorGrading	game,off,on		allows disabling developer implemented color grading that can wash out some locations or cause significant transitions in interiors
CustomAutoExposure	game,off,off_medium_brightness,off_darker,on,on_medium_brightness,on_brighter		provides an option for a more stable autoexposure that is not quite as adaptive - should result in a more stable image
DLSSAutoExposure	off,on		Toggles DLSS Autoexposure (a DLSS feature) in most games this should be on, but some games like Stalker2 can have artifacts with it on
Denoiser	game,none,temporal,temporal_high,rayreconstruction,rayreconstruction_temporalgihigh	F2	Changes global illumination and reflection denoising - allows enabling ray reconstruction - temporal high settings increase the amount of temporal information to reduce noise at the cost of ghosting
DepthOfField	game,off,on,on_less_blurry		depth of field control - off reduces noise in cutscenes
EnableKeybinds	off,on		Enables individual setting keybinds if they are available, does not change global keybinds
ExtendedDrawDistance	game,low,medium,high,epic,insane		separate objects from foliage like stop signs, puddles, and buildings
ExtendedFoliageQuality	game,high,epic,extreme,ihatepopin,keepdistant_high,keepdistant_epic,keepdistant_extreme,keepdistant_ihatepopin	CTRL+F9	extends the in game foliage quality, high is higher than vanilla epic, keepdistant variants keep r.ViewDistanceScale at 1.0
ExtendedShadowQuality	game,veryhigh,epic,insane		all are higher than vanilla - recommend setting epic in game and then changing this setting
FGCutscenes	off,on,on_spammy		enables support for frame generation in cutscenes - both DLSSG and FSRFG are supported - on_spammy attempts to reenable frame generation more frequently and for many more actions including PDA and menus
FixHairVRAM	game,off,on		fixes hair VRAM leak at high resolutions and reduces hair vram consumption for slightly lower fps
FixSkylightInReflections	game/0-1		Skylight reflection intensity (0.0 = off, 1.0 = maximum, game = use game default, 0.5 recommended)
Fog	game,off,on		Turns fog on or off, if on_with_lumen is provided then it allows enabling fog in lumen space (GI and reflections)
HDR	game,off,on		HDR output control this setting provides a mechanism for using HDR in borderless fullscreen which the game does not support by default
HighQualityTracing	game,off,on	CTRL+F8	More accurate tracing of meshes for reflections and global illumination
LODBias	game,off,minuspoint5,minus1,minus1point5,minus2		Forces textures to be higher resolution, -0.5 is the safest, more can cause frequency patterns to appear, some games benefit from more than others
LODDistanceScale	game,high,veryhigh,epic,ultra,insane		Draw static meshes and foliage at higher quality further away
LightingAO	lumen,lumen_less_noise,ssao,gtao	F7	Changes ambient occlusion method between Lumen, SSAO, or GTAO - lumen_less_noise is the safest default as full lumen may introduce shimmering/noise
LightingMaxIntensity	game/10-50		Maximum ray intensity for Lumen, lower values are darker and result in less noise (10-50)
LightingMinimizeLeakage	game,on		override some of the lighting settings to minimize light leakage as an alternative to increasing all lighting quality, no need to use this setting if very high lighting quality or above
LightingMode	game,standard	F8	no other lighting modes at this time
LightingQuality	game,standard,high,veryhigh,epic,insane	CTRL+F10	Standard lighting quality is the recommended default, higher lighting qualities will reduce noise and increase the detail of lighting in the scene particularly around smaller object
LightingResolution	low,medium,mediumhigh,high,veryhigh,epic,insane,extreme	F6	lighting resolution quality - higher quality is more accurate lighting at the cost of performance - standard in-game epic (the same as epic in this setting) is typically x16 downsampling which is usually not necessary, medium (x32) is the minimum recommended
LightingUpdateSpeed	default,high,epic,insane		Allows making global illumination update faster
LumenDiffuseColorBoost	game/0-5		Increases diffuse lighting especially from local lights
LumenTraceDistance	game/20000-60000		Maximum distance of objects traced in the lumen scene
MotionBlur	game/0-1		U+ improves motion blur quality in every game by default, recommend a small amount of blur ~0.2
ReduceInputLatency	game,off,on		reduce input latency at potential FPS cost if not GPU bound
ReflectionBias	game/0-1	F9	Adds smoothing to reflections to make them more mirror like, a small amount is usually beneficial
ReflectionQuality	game,high,veryhigh,epic,insane	F10	Allows more surfaces to be included in reflections, in some games increasing this can cause some noise
Reflex	game,off,on		NVIDIA Reflex low latency
Sharpness	game/0-1		Control UE tonemapper sharpness - recommend setting this to 0 and using RCAS through reshade
SkylightIntensity	game/0-3		Skylight is a flat amount of light added to the scene, it mostly effects outdoors unless a game uses it to light interiors
SunMoonIndirectIntensity	game/0-20		Indirect or bounce lighting intensity for the sun or moon
VSync	game,off,on		allow forcing vsync - helps latency in some games
Vignette	game,off,on	F3	vignette effect control
