Disable / Enable Shaders Compilation



PLEASE ENDORSE. THANKS







If Vortex .pak File Doesn't Work Use Manual Installation:




Start the game at least once and compile shaders.
Paste the code into the engine.ini file


[SystemSettings]
r.PSOWarmup.WarmupMaterials=0



=0 disable
=1 enable

Engine.ini path (Steam):
%localappdata%\Stalker2\Saved\Config\Windows

I've made the fix for myself and shared it with my friends. Use it as is, stalker.

Detailed instructions
(for those who hold the mouse like a grenade)

Precompile shaders for your current settings:

start the game and configure your graphics settings.
exit and restart the game to generate shaders for the selected settings.
quit the game again after the shaders are fully compiled.


edit or create the engine.ini file:
locate the file:
\%localappdata%\Stalker2\Saved\Config\Windows\Engine.ini

paste the path into the Windows run dialog 
win + r

if the file doesn’t exist, create it.

Use a text editor like Notepad or a file manager. Add the code:
[SystemSettings]r.PSOWarmup.WarmupMaterials=0
then select File on the top menu > Save as and name Engine.ini use the .ini extension in the file name, 
then where "save as file type" below is, select All Files, click save

or add the following line somewhere under [SystemSettings] in the Engine.ini

r.PSOWarmup.WarmupMaterials=0

; =0 disable compiling shaders each time, =1 enable



Enable shaders compilation
If you reinstall GPU drivers, change hardware, or modify graphics settings, add the 1 value instead of 0

r.PSOWarmup.WarmupMaterials=1

This allows the game to rebuild shaders for the new setup.
That's why I'm sharing it as ini file instead of the mod .pak file

More suggestions:
Update GPU Drivers: Ensure your graphics drivers (NVIDIA or AMD) are up-to-date.

​Shader Cache Size: For NVIDIA users, increasing the Shader Cache size in the NVIDIA Control Panel can help.
This setting can be found under "Manage 3D Settings"​

For AMD users, check the official AMD support page for guidance on managing shader cache​

BIOS Update: Some newer Intel CPUs (13th and 14th gen) users have experienced shader compilation crashes.
Updating your motherboard's BIOS may resolve issues related to CPU performance during shader compilation​

VRAM Issues: If you're getting VRAM errors despite having sufficient memory,
try lowering in-game graphics settings or disabling certain resource-intensive features like ray tracing​

Increase Virtual Memory: For users with limited system memory,
increasing virtual memory or adjusting page file settings may also improve stability during shader compilation​
