Wondering how registry affects computer overall

In order to get Star Citizen to download, had to create a new multi-string value called ForcedPhysicalSectorSizeInBytes the value being 4095.

The game downloaded, but I'm unsure if I should keep it because I don't know how that affects the PC overall when not playing the game. I have no idea what it means and I don't want to mess up my PC so it would be really helpful if someone could explain

The location is computer/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Stornnvme/Parameters/Device
