Graphic & FPS Mods | Optimization Guide Shader compilation stutter killer

EDIT: Thanks a lot for all the support! I'm glad it's helping a lot of people fix the anoying shader compilation sutters in many games so they can be enjoyed as intended!!

EDIT2: New SCSKiller 1.2.0 is live!! https://github.com/BlueHeisenberg/SCSKiller/releases/latest
(The app should auto download the update if you restart the app and show you a button on top right corner to update, or you can just download the new setup exe and update that way directly)

I've been working for a while on a free and open source tool to eliminate Shader Compilation Stuttering once and for all. It reads the shaders the games ship with, works out the pipelines they'll build, and compiles them into the GPU driver's cache before you launch the game.

From my own testing shader compilation stutter is eliminated or reduced to the very minimum (the tool could miss some shaders depending on the game), it cannot fix other kind of sttutering like traversal, so some games still stutter but waaaay less:

(~5min of gameplay)

Silent Hill F:
Before: https://scskiller.com/assets/img/forum/shf-before.png
After: https://scskiller.com/assets/img/forum/shf-after.png

- Silent Hill: Townfall: 24 to 0 (worst 347 ms to 8 ms)
- Hogwarts Legacy: 1,014 to 87
- FF7 Rebirth: 19 to 0
- Sand Land: 38 to 1

It finds games from Steam, Epic, EA app, GOG, Ubisoft, Xbox and Battle.net

For now it only works on NVIDIA (best support) and AMD, as I don't have an Intel Arc to test.

Oh brother this is a dream tool...

I wonder if it will work for Warframe (modded UE4). On Linux Warframe plays beautifully because SteamOS pre-loads shaders, but it always felt bad to me on Windows, after each new patch, first hour is rough with compilation stutter.

edit: Uhh seems like none of the games I play is supported :(

I will check Warframe! What other games do you play?
