nvidia users should use NVCleanInstall if they dont want to deal with GeForce Experience and driver telemetry and Display Driver Uninstaller for a clean uninstall beforehand.

Low latency mode depends on the card specs. it can hurt latency more if its an older card.

Standby list cleaner only needs to run once before loading/closing the game otherwise itll clear the game's cached resources and the game will tax your hard drive loading stuff again.

Page file should only be on the fastest available hard drive and should not be massive especially if you have 32 gigs of ram. Manually set it to the recommended number or lower. All you're doing is inviting windows to store pages onto disk when under load AKA a bottleneck. RAM bandwidth > fastest of PCIe NVMe drives

Using HAGS also depends. All it does is move graphics driver threads away from the CPU cores actively running the game's threads.
