Performance regression at lower upscaling quality with FSR 3.

> Here's an example of the upscaling performance drop just when exiting Tolvald's Cave. > Ultra Performance results in 15 fps. > Performance results in 39 fps. > > It might have something to do with vram load. > Save, quit and load the same scene shows 80% vram load and no performance issues in any of the presets. > > Edit: It seems to also happen with much lower vram usage. While upscaling is bugging out like this I can disable the utility shader and fps hits the cap, when the shader is re-enabled the fps tanks again. > > <img width="1491" height="618" alt="Image" src="https://github.com/user-attachments/assets/78a46876-17f3-463a-89ff-6743c8038f48" /> > > <img width="1447" height="628" alt="Image" src="https://github.com/user-attachments/assets/f8bdd7e9-3eac-4f22-90bf-bc8a3b18cf13" /> _Originally posted by @Almoped in [#2125](https://github.com/doodlum/skyrim-community-shaders/issues/2125#issuecomment-4317147436)_
