Want to unlock advanced graphics settings or hidden features on NVIDIA? NVIDIA Profile Inspector is your perfect secret weapon.
This wondrous application allows you to tweak settings at the hidden driver features level that aren’t accessible through the standard NVIDIA Control Panel, thus ramping up their leverage over performance, visual quality, and compatibility.
In this comprehensive guide, you’ll learn what NVIDIA Profile Inspector is, how to use it, and which hidden driver features you can unlock safely.
