About This Mod
The Problem with Traditional INI Tweaks
You want better performance and less stuttering in Mortal Shell II. You find an Engine.ini tweak. You download it. Then you need to find your local AppData folder. Then you have to navigate to Saved\Config\Windows. Then you need to manually paste the file. Then you have to set it to Read-Only. Then you have to choose between VRR and No VRR variants. Then you wonder if you got the right variant. Then you have to test it.
This is the "Mantella-style" headache—minutes of folder navigation, file management, and variant selection for what should be a simple performance tweak.
Our Solution: Optimized Engine Settings, Zero Manual Config
Ultimate Engine Tweaks brings over 1 year of iterative work with 50+ UE5 games to Mortal Shell II. The definitive, optimized, custom Engine.ini. Removes most stuttering. Improves performance and stability. Decreases input latency. Improves picture clarity by removing Film Grain & Chromatic Aberration, optimizing Motion Blur, and optimizing DLSS/FSR Upscaling. All with no visual loss.
But we didn't stop at the tweaks. We completely re-engineered the installation process.
Forget manual folder navigation and file management. Our all-in-one installer handles everything:
Automatic Config Folder Detection – The installer finds your Mortal Shell II config folder automatically. No manual navigation to %localappdata%.
VRR Detection and Selection – The installer detects if VRR (G-Sync/Freesync) is enabled and selects the correct variant automatically. No manual decision-making.
One-Click Deployment – The installer places the Engine.ini file and sets Read-Only automatically. No manual file management.
Uninstallation Made Simple – The installer can remove the file and restore defaults with one click.
