You can check this thread https://forum.sector3studios.com/index.php?threads/highest-quality-driver-settings-for-nvidia-cards.4330/ In post #14 I shared my settings in inspector. In your sig, I don't find GPU specs. But overall, graphics settings is mostly individual preference (FPS vs Quality, and then various aspects of quality itself). My main find is that I get no shadow flicker with SGSSAA enabled.
Be aware with the lastest couple of versions of inspector, if you look at the Raceroom profile it doesn't have the correct .exe it has mss32.exe for some reason, your need to import the correct .exe and lose that other one.
You can add more than one .exe to an existing profile or you make a fresh user created profile with the correct .exe.
Ah, think I've worked it out now, I've added rrre.exe to the existing RaceRoom profile, then removed mss32.exe from the profile (what is that?)
The program allows users to analyze characteristics of the chip and memory, the degree of GPU load and a number of other parameters. It also can change the values of parameters affecting the performance of the video card such core frequencies, memory, voltage and temperature. Download Nvidia Inspector 3.5.0.0 Latest Version
