Microsoft adds Variable Refresh Rate For Games that lack Support

by Hilbert Hagedoorn on: 06/04/2019 05:05 PM | source: microsoft | 30 comment(s)

With Windows Version 1903, Microsoft have added a new toggle in Graphics Settings for variable refresh rate. Variable refresh rate (VRR) is similar to NVIDIA’s G-SYNC and VESA DisplayPort Adaptive-Sync.

This new OS support is only to augment these experiences and does not replace them. You should continue to use G-SYNC / Adaptive-Sync normally. This toggle doesn’t override any of the settings you’ve already configured in the G-SYNC or Adaptive-Sync control panels. This new toggle enables VRR support for DX11 full-screen games that did not support VRR natively, so these games can now benefit from your VRR hardware.

You won’t see the slider unless your system has all of the following. If any of these are missing, you will not see the toggle and the feature will not be enabled for you.

Windows Version 1903 or later
A G-SYNC or Adaptive-Sync capable monitor
A GPU with WDDM 2.6 or above drivers, that supports G-SYNC / Adaptive-Sync and this new OS feature

This feature is disabled by default, but you can turn it on and try the feature out. If you run into any unexpected issues while gaming, turn the feature off and see if that resolves the issue for you. Thanks SH SOTN for this news submit.

If it's UWP only, can at least State of Decay 2 have any benefit from it?
Because last time I tried it, frame pacing was really bad.

I don't have the option in v1903, build 18362.145 @ my native 3840x2160 resolution, so it appears that if you don't have a Freesync-Gsync monitor the option does not appear at all. Still cannot figure the advantage of Freesync/Gsync--as the examples the OEMs use to illustrate "what your monitor looks like without it" look much worse than what I'm accustomed to--and the examples they use to illustrate what VRR looks like in action look exactly like what I already see. In fact, if my monitor looked as bad as the OEM's say it looks without x-sync I'd be convinced something was wrong somewhere in my graphics stack...

It makes a noticeable difference, but you have to experience it to see it. I once tried to overclock my 4K/60 FreeSync monitor - I tested it at 65 Hz and ran a game but the results were horrible (stuttery, choppy). I suspected that it had disabled FreeSync and the windmill demo confirmed it. This put an immediate stop to my overclocking test, as the results weren't worth it if it disabled VRR.

Unfortunately, VRR cannot fix frame pacing. Garbage in, garbage out.
