The main settings application for PowerToys.
Asking. Settings is a basic WinAppSDK app so chances are this has something with them.
FWIW this seems to be due to a longer standing issue with how either Windows or the GPU driver are managing interactions with High Refresh displays and/or frame synchronization tech like GSync / Freesync.
This also affects the rewrite of the command prompt ( Terminal : https://github.com/microsoft/terminal/issues/649 ), and basically any application that gets upgraded to its own plane due to Windows' added support for multiplane rendering in 2021H2 and newer. AFAICT if the application doesn't specifically do something ( like updating the entire frame regardless of changes ) to avoid being placed in a frame-sync render mode, it will be put into vrr by the driver, and apps that don't update every frame generally cause vrr implementations to stall until their timeout while waiting for the new frame, with the stall time resulting in a 60hz ( or less ? ) update for the application's pane - which is exactly what we're seeing.
My typical solution to this is to manually add the application to the nvidia control panel, and enforce the display type as "fixed refresh" - see https://twitter.com/fire/status/1497074121095663652 So far I've personally seen it affect 1Password, Luminar AI / Luminar Neo, Powertoys, and the handful of UWP apps I've tried using.
In this specific case I'm using additional settings, but I honestly don't know if they have any real impact beyond the Monitor Technology setting:
Ideally this is something Microsoft would either resolve first party or take up with gpu driver implementers to resolve wholesale, but at least we have a general purpose workaround
This still seems to be an issue for me in PowerToys settings in v0.75.
When navigating around the app with scroll, and in-app animations, it feels slow and stutter-y. Scroll feels particularly slow. Not sure if it is 60hz, but it feels like 30 Frames Per Second or less.
I am using a G-Sync Monitor than can get up to 175Hz, and an RTX 4080.
I only noticed this issue once PowerToys was moved to WinUI 3.

Not sure if it was on your end, a driver update, a Windows App SDK update or a Windows Insider update, but scrolling is smooth now 🙂
