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

Overview

Ultra+ for Stalker 2 significantly reduces the amount of noise and improves fidelity while maintaining performance. It also addresses significant issues with the games color grading, exposure, and weather.

Game Tips

Configuration

Setting Options Keybind Description
AutoApplyConfig off,on   automatically reload settings when config changes - primarily to be used with the UPM overlay
BetterReflectionSDFs game,off,on,on_epic,on_insane   Increases the resolution of meshes in global software lumen space, most noticeable in reflections
Bloom game/0-3   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
CustomLocalExposure game,shadows,all   local exposure profiles loaded from PPVSettings.ini; use -1 for any profile value to preserve that property game default
DarkerNights off,on   enables dynamic darker nights by reducing skylight intensity at night
DebugLogging off,on   enable verbose debug logging to UE4SS console - use ALT+D to toggle at runtime
Denoiser game,none,none_temporalgihigh,mintemporal_temporalgihigh,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
DirectionalLightIntensity game/0.0-1.0   Reduces intensity of the sun and moon
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
FixColorGrading game,on   fixes extreme values in color grading that result in blown out highlights requiring post correction
FixWeatherSkylight game,on   reduces excessive Sky Light intensity in certain weather conditions to sane values while preserving natural time-of-day variation
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   !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,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/3-40   !Maximum ray intensity for Lumen, lower values are darker and result in less noise (10-50) - 3 is vanilla
LightingMode game,uplus,uplus_experimental F8 lighting mode - uplus for default enhanced lighting - experimental for more dramatic changes to shading
LightingNoiseQuality game,standard,high,veryhigh,epic,insane   Higher noise quality reduces noise at the cost of performance, but costs less than increasing lighting quality
LightingQuality game,medium,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,high,veryhigh,epic,insane 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/20000-100000   Maximum distance of objects traced in the lumen scene
MoonGlow game,off   disables the low resolution moon glow texture
MotionBlur game/0-1   Ultra+ improves motion blur quality in every game by default, recommend a small amount of blur ~0.2
RadianceLightingScale game/1-10   !Intensity scale of stalkers custom radiance cache - low values will fix guns - suggest increasing indirect and decreasing this as a balance - 10x is vanilla
ReduceInputLatency game,off,on   reduce input latency at potential FPS cost if not GPU bound
ReflectionBias game/0-1   Adds smoothing to reflections to make them more mirror like, a small amount is usually beneficial
ReflectionQuality game,medium,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
SkylightIntensityNight game/0.0-2.0   Night skylight intensity multiplier (0.0-1.0), used when DarkerNights is enabled
SunMoonIndirectIntensity game/0-20   Indirect or bounce lighting intensity for the sun or moon
TranslucentReflections game,off,on   adds detailed reflections to translucent materials - may be preferable to turn it off in this game due to inaccuracy
TuneLightSources game,on,on_overhaul   on adds a minimum source radius to fix shadow penumbra, on_overhaul also reduces light intensities
Upscaler off,dlss_4.5,dlss_rayreconstruction,dlss,other   select your active upscaler to auto-configure denoising - dlss_4.5 uses Denoiser none_temporalgihigh, dlss_rayreconstruction uses the rayreconstruction Denoiser variant, both force MegaLights no-temporal variants; other upscalers use temporal Denoiser and MegaLights variants. off leaves Denoiser/MegaLightsQuality under manual control
VSync game,off,on   allow forcing vsync - helps latency in some games
VignetteIntensity game/0-2   Vignette intensity scale (0.0 = off, 1.0 = default, 2.0 = double, game = use game default)
