You can set the priority of a program you want to run using Regedit but unfortunately, it is not possible to do the same to set affinity, as in most cases, you don't need to change the processor affinity unless for an older application or game that doesn't support multithreading. For this example, I will be using MSPaint.exe.

    The reason for the error message is that your reg file doesn't have the "Windows Registry Editor Version 5.00" line at the top. Without that line, I get "Cannot import foo.reg: The specified file is not a registry script. You can only import binary registry files from within the registry editor." When I then add that line and try again, it works properly.

    Took me 3 hours to change my audio driver so I have no lag with microphone.

    Program start, not as service, but on startup, had to edit registry by hand, because:

    This method don't work on my up to date windows 10. 21H2. 19044.1526 and never ask for that:

    Windows Feature Experience Pack 120.2212.4170.0

    Your method gives me a : said file is not a registry file, can only import binaries...

    And I followed your process step by step, with copy-paste. All paths are OK, I am admin, ???

    app.exe Set Priority.reg

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\RAVCpl64.exe]

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\RAVCpl64.exe\PerfOptions]
    "CpuPriorityClass"=dword:00000003

    Plus, you should have give the normal method, add key, and so on as an alternative.

    I know now why I switch to linux five years ago, hte lag was minimal, and i fixed it in 80 seconds...

    Just so you know, need to be in windows to use oculus VR, else...

    Best regards,

    Robert Garand.
