Stutter exactly every Second when Cursor is used by the in-game Camera.

Question

Hello, recently I've clean installed my Windows to fix other performance issues, which it did fortunately, although, I have come across the old annoying problem with games. It has been a bug before already, when I once got forced to update to 24H2. When I reverted it to 23H2 it was immediately fixed, now since I did clean install, I had to end up on 25H2. I hope I can get some help here as it is specifically an issue with Windows 24H2 and above. I never had this problem below those recent versions.

Heres how it looks in-game, I've noticed that it starts happening whenever something loads, where my cursor ends up being de-focused from the game. Ex. If ill play Helldivers 2, go to the games menu, and back in the game, where the camera gets used again, it'll keep happening until I tab out or press the win key.

It seems to be tied with my framerate, as it ends up lowering itself to 71, rather than the supposed 72, and due to the fact my refresh rate on freesync is fractional, at 71.91Hz, it stutters exactly every second, it happens on borderless/fullscreen both. Disabling fullscreen optimizations doesnt help either.

Now the weirdest part is, when I opened OBS, it stopped happening for the most part. I tried the usual ways to trigger this issue, and it just wouldnt happen. After enough testing, it can still happen even with OBS in the background, but much less, so this is my temporary solution for now, I just wish there would be a fix, I have no way to revert to 23H2 anyway.

And to be more specific, if I put my OBS to system tray, itll happen again, so it has to be an actual open window. If anyone here could help resolve this, it would be greatly appreciated.

Hello Yato,

Welcome to Microsoft Q&A forum.

Based on what you've described, this seems to be something to do with focusing. Just before we proceed, can you please check if the Game Mode is currently turned ON? Also, can you please try to turn on Focus mode while playing game to see if it improves?

If possible, can you please send me a short video of the issue so I can take a look at it?

I'm waiting for your reply.
