Not needed if your monitor supports Freesync or G-Sync and capable GPUS

Thanks for your answer. Good to know. All my Games are running so much better. vrr from Windows is broken. I also have no more that flickering issue.

Glad its better for you now. Only reason I'd ever think it'd be of use would be if you used an Intel GPU..but they support the current versions already. MS just wasting time doing something half ass'd that no-one needs/wants

Yes that is true and makes sense.

You still have to actually enable it.
Like on an NVIDIA GPU, within. NV CP you have GSync options and you have a setting listed in Manage 3D Settings regarding VRR to either let the software control it or the Display.

Pretty sure with AMD you just go into that software and enable FreeSync and this should hard enable VSync ON. What I'm not sure of is if AMD allows the user to set Full Screen only or All Windows. Like we can do with GSync on NVIDIA GPUs

First ensure to set the OS Desktop to native Display screen res a d highest available refresh rate before you attempt to make other GPU/Display settings changes

never trust windows to change settings for gpu
get the correct drivers, never use windows update for drivers
and change the settings yourself

disable windows driver updates, and reinstall correct drivers for chipset/mobo/lan/audio/wifi from the board mfg

and if windows does a feature update or rollup, reinstall the correct drivers again
windows likes to default to reinstalling generic drivers again

Yes aside from a DPI % or enable of HDR do everything else in the GPU software, Intel / AMD / NVIDIA. If using NVIDIA you can adjust GPU clocks, power limit, throttle temp, fan %, fan curve settings with MSI Afterburner
