HOW EXACTLY to do this please.
To ensure your DCS.exe, vrserver.exe and vrcompositor.exe are working most efficiently with your CPU set their priority to High, you can do this manually, or via a script I do it via the registry, add the following keys to the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\DCS.exe\PerfOptions
"CpuPriorityClass"=dword:00000003
