I use this free, open-source tool on my Nvidia GPU for better DLSS and more control over how my games run
If you have an Nvidia GPU, you need NPI.

Nvidia has increasingly given more control to users with its recent software updates. Settings have slowly migrated out of the Nvidia Control Panel into the Nvidia app, GeForce Experience is dead, and you now have access to features like DLSS overrides directly within Nvidia's software. Even with more control, there's one free, open-source tool I always leave installed on my PC: the Nvidia Profile Inspector.
