Place the "V2 Performance Booster" folder in your LML folder.

If you don't have an LML folder, then download LML Lenny's Mod Loader. After downloading Lenny's Mod Loader, copy the contents within the "ModLoader" folder to your Red Dead Redemption 2 game folder (where RDR2.exe is located). Then place the "V2 Performance Booster" in the LML folder you copied over.
