S.T.A.L.K.E.R. 2: Heart of Chornobyl - Stutter & Lag FIX

If you are having problems with stutters and quick lag & fps drop, I highly recommend using my solution. It will make your game smooth with ~stable fps, it worked for me. No stutters, no fps drops, smooth gameplay.

If the previous method did not help you, use this one. For the Steam version: %localappdata%\Stalker2\Saved\Config\Windows

1) Create and open Engine.ini
2) Paste this:

[SystemSettings]
r.Streaming.PoolSize=12288 ; Only for 16GB VRAM. For 12GB use 9216, for 8GB use 6144, for 6GB use 4608, for 4GB use 3072

Delete Film Grain and Chromatic Aberration

For the Steam version: %localappdata%\Stalker2\Saved\Config\Windows

1) Open Engine.ini
2) Backup original (Clone original Engine.ini to desktop)
3) Open Engine.ini, and paste this:

[SystemSettings]
r.Tonemapper.GrainQuantization=0
r.FilmGrain=0
r.NT.Lens.ChromaticAberration.Intensity=0
r.SceneColorFringeQuality=0

Disabled Ray Tracing and its other components for more FPS

For the Steam version: %localappdata%\Stalker2\Saved\Config\Windows

1) Open Engine.ini
2) Backup original (Clone original Engine.ini to desktop)
3) Open Engine.ini, and paste this:

[SystemSettings]
r.RayTracing=False
r.RayTracing.Shadows=False
r.RayTracing.Reflections=False
r.RayTracing.AmbientOcclusion=False
r.RayTracing.GlobalIllumination=False
r.RayTracing.Lighting=False

Hi! i was trying to play on my pc a Lenovo with ryzen 5800h 16gb of ram and a 4060 6gb, the FPS with frame generation are very good buth the stuttering every minute fcked up the experience, i noticed the problem was on interiors or near constructions with interior, for example running on the forest doesnt present stuttering but every time i was near a house the stuttering appared

So after trying various fixes i tried this and i dont have more stuttering it works just fine, i knew it was a VRAM related problem

Thank you very much!

Hey, Thanks for your feedback, this is very important to me (◔◡◔)

Thank you again!

To reconfirm that it worked i played for 1 hour with no more stuttering, only minimal stuttering but the kind that i have on every game, after all its a notebook and that happens because of thermal throttling

Before your fix was IMPOSSIBLE to play with that stuttering happening very often, even with all the specs in low it was impossible now im playing with this config:

Textures MID
Hair EPIC
Objects detail EPIC
Effects MID
Materials MID

Postprocessing MID
Antialiasing MID
Motion blur EPIC
Depth of field EPIC

FSR on quality
FSR Frame generation ON

Shadow quality HIGH
Ilumination MID
Reflects MID
Shadow MID

Clouds, fog, Sky, foliage, EPIC

Draw distance MID

Im playing it on spanish so maybe the config items have different names on english

sometimes i have 90-100 fps
but average moves between 40 and 60 with some lows

very playable

This on a
Lenovo Legion 5
Ryzen 5800H
16gb DDR4 RAM
NVIDIA RTX 4060m 6gb
Win11 24H2 with latest updates
NVIDIA drivers WHQL 566.14
Game installed on a Kingston pcie4 @ pcie3 2tb ssd
System on a SKHynix pcie3 512gb ssd

I recommend lowering the "HAIR" settings to LOW, because you can win +15-30% in FPS (no visual changes). Watch this: https://imgur.com/a/RVOMPLh

Hair on LOW now

Theres a way to limit the use of RAM too? (not the vram)

okay I figured it out..

just ignore "Disabled Ray Tracing and its other components for more FPS".

This worked for me, if it didn't work for you, try re doing it line by line I guess until u figure out what was the exact issue for you.

If your game is on Steam Library -> right click it -> click on properties then in the "Launch Options" field paste that commands: -xgeshadercompile -nothreadtimeout -NoVerifyGC

This also help you!

THANKSSSSSSSSSSSSSS A LOT

Sorry for the possibly dumb question, but what is 10 vram then? I have the 3080.

10 gb vram == 7680

[Wozherd$🐧]

How come r.Streaming.PoolSize=12288 requires 16GB VRAM?
