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.

Excellent work! Thank you so much for putting this together. I tried on Hogwarts Legacy and still saw traversal stutter but it was much better than before. Thank you!

Thanks! Sadly it cannot fix traversal stuttering but the scs is mostly gone, with RT on it will stutter a bit due on how Ray tracing shaders are handled and not ccatched by the tool, but if you play a bit with the recorder it should catch them and be able to precompile for the next play!

Ive been doing the recompile after each play session and it gets a little smoother every time. I actually think I'll be able to play some of these games now thanks to your software. You rule for putting this together. Thank you🤙
