This my case that gives a video demonstration, This issue is related to polling rate potentially and the migration from UWP to GDK
I noticed this immediately, I stopped playing for 2-3 months because of this. And now only 125hz polling is playable to me. I really want to be able to play on 1000hz polling again which is average. I play on Oled 1440p 280hz so the stuttering is even more of negative impact and highly noticeable and 125hz polling with a 280fps does not match up well.
The controller test on max sensitivity was what I tried also. It’s smooth, you swipe a mouse even on 240fps plus and it looks like your frames are dropping even though with a fps counter you can see it’s stable.
