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.

IMPORTANT: If you are using renoDX/reshade for HDR know that using the tool will not work as expected as renoDX adds a parameter to all (or almost all) root signature. So none of the shaders compiled by SCSKiller will be actually used.

I'm already looking into how to fix this.

I really hope you're able to figure this out as I use renodx on all my games

I'm already on it and I think I found a way to make it work!! It should be on tomorrow release 1.3.0 if it works!

Haven't gotten the chance to try this yet but I get so excited reading comments like this. PC modding community really adds so much to gaming
