MQDH v6.3.x - slow and unresponsive

MQDH software has been mostly smooth on my windows PC but since upgrading it to v6.3.x I am constantly facing problem with MQDH freezes when scrolling, clicks are unresponsive and switching tabs are also slow. 

Another problem is every time I turn on my PC, there's this window's permission pop-up asking me to grant access to Quest Link, why does it ask me every single time I turn on my PC? It's super annoying.

My PC:
- Windows 11
- 24 GB RAM
- 1 TB Free Storage
- AMD Ryzen 5 3400G processor
- 2GB AMD Graphics card

support needed

    v6.3.x introduced some issues from some devs, if you check the forums you’re not alone.

    For the lag/freezing:

    • Try reinstalling MQDH cleanly (uninstall + delete leftover folders)
    • Disable hardware acceleration (if available in settings)
    • Close background apps (MQDH can spike CPU on some GPUs/CPUs)

    For the permission popup every boot:

    • That’s Windows UAC + Quest Link service, it happens if the service isn’t running with elevated (admin) rights
    • Fix: run MQDH/Link as admin once, or disable auto-start and launch manually

    If it’s still difficult to use some are staying on older MQDH versions until it stabilizes.
