What is Ultimate Engine Tweaks Mod for Stellar Blade
Anti-Stutters – More Performance – Lower Latency – Better Clarity – Lossless
Definitive Unreal “Engine.ini” changes with the goal to remove most stutters, improve performance and stability, decrease input latency, improve picture clarity. All with no visual loss.
For displays with VRR support:
Download the VRR-optimized version for dynamic refresh rate synchronization and smoother gameplay
For standard displays (non-VRR):
Use the fixed refresh rate version for stable performance on traditional monitors/TVs
Alternative combined version:

How to Use the Ultimate Engine Tweaks Mod for Stellar Blade
Q. I can’t locate the right path where to paste the Engine.ini
A. Just press Win + R and copy/paste the following path in the box it will appear:
%localappdata%\SB\Saved\Config\WindowsNoEditor
then hit enter and you will end up in the correct folder where to put the Engine.ini
Q. When I launch the game the modded Engine.ini is automatically deleted or reverted to default one?
A. Right-Click on my Engine.ini -> Properties -> make sure the “Read-Only” box is selected -> Apply/OK
It’s important. If the file keeps getting deleted or reverted, un-tick the “Read-only” box -> Apply -> re-tick it -> Apply/OK
Q. When I right click on Engine.ini Properties I have a security warning stating “This file came from another computer and might be blocked to help protect this computer”?
A. That’s just a warning that tells you the file comes from another PC (mine). It will still work without issues.
Q. My CPU usage is skyrocketing to 100% after the mod
A. This is initial shader compilation which may continue in-game even after the initial precompilation loading screen. Wait 4-5 minutes at max to let the game finish it and CPU usage / performance will return normal.
Q. I have the same or worse performance after the mod
A. For super high-end PCs the performance difference may be small but you should still notice reduced stuttering, more consistent 1% lows, lower input latency and better visual clarity. For mid and low-end PCs the fps difference may be much bigger on top of all that.
If for some specific PC configs you end up with worse performance try deleting shaders cache including the files which end with “cache” located in the “Saved” folder from the above path and open the game again.
If you still have worse performance just delete my Engine.ini and on next boot the game will recreate its default one.
You don’t need to verify the game files or reinstall it to restore it to what it was before the mod.
Q. Will this mod downgrade visuals/graphics?
A. No 🙂
“Lossless” means this mod was created with the goal to optimize everything I could in Unreal Engine without sacrificing visuals and/or altering your in-game graphics’ choices (except for Chromatic Aberration and Film Grain removal which you can still revert back by changing their described lines within the Engine.ini itself)
With improvements to AA, Sharpening, DLSS/FSR/XeSS you should actually have even better visuals after the mod.
Q. Can I use it together with Stellar Optimizer, SB Ultra+, SB “Uber-Tweaks” or whatever?
A. No.
Don’t mix my Engine.ini with other mods which will do their own optimization tweaks to the engine or they may conflict with each other.
You can try each of them separately and choose the one which performs the best for you and only use that exclusively.
You can still install any other “non-optimization” mods.
Q. Will this Engine.ini disable Achievements?
A. Straight and simple: no. 🙂
Q. Will this Engine.ini work/load also with future game patches?
A. Yes. Just be sure the file is set to “Read-only”
Q. The game crashes when opening it and/or during gameplay after a while
A. Make sure your PC is actually stable under sustained load (e.g. you are not using an excessive overclock/undervolt). You can test it using OCCT (launch a 1 hour “CPU+RAM” test, followed by another 1 hour “3D Adaptive” test. If you have even a single error, you need to fix your PC stability first)
Another solution if you use Vortex is to open it, go to the game section -> Load Order and click the last button ⛔ on the top bar (“Reset Plugins File”)
If even doing the above you still crash, try lowering PoolSizeVRAMPercentage=60 (both in [TextureStreaming] and [ConsoleVariables] sections of the .ini), then remember to set the .ini to Read-only again.
Q. I noticed you were extremely fast in creating the mod after the game launched. How?
A. The .ini is the result of months of testing also with other UE games.
The feedback gathered from all of them made me expand/improve it over time and, yes, it is compatible with all UE games (with minor modifications), that’s also why you saw me uploading the mod so fast at the beginning.
