Windows 10 start menu stuttering

[JHack93]

Hi all, I've been experiencing this issue for long time and googled a lot before trying to ask here.
Basically, when opening the start menu (regardless if using the mouse or the keyboard) the framerate drops gradually but quicky from my native 120fps all the way dows to 20fps and sometimes to only 2fps. Then it stays at very low fps until I move the cursor inside the menu (with a visible stuttering) and then the framerate starts increasing gradually to normal.
It happens occationally when opening other windows. The fix to bring the framerate back to normal is always to bring the cursor inside one specific window (very likely the one that caused the stuttering to happen) and move it around a bit or swapping window focus to a different one (desktop included).

I want to specify that the system is not busy with heavy tasks when that happens, but it's usually just on idle. When gaming, I never have issues or sudden fps drop. It only happens when changing focus or if a new window opens.

I've done a fresh windows install in occation of the new May update and the issue still happens. All drivers are updated to the latest builds.

I tried to disable or close backgroud application one by one to see if any of those were conflicting, but none of them solved the issue. I tried to disable G-Sync but still nothing.

I've followed any guide I've found related to the same or similar issue, but none of them seemed to work. So I'm here to ask if any of you know what to do.

My specs are as follow:

Asus ROG Maximus XI Extreme x390 (Bios version 1502);

Intel i9 9900K (5GHz all core, 4.8GHz Ring, 0 AVX Offset, 1.250v core) tested stable with OCCT and Cinebench;

G.Skill Trident-Z RGB 32GB (4x8GB) DDR4 3200MHz 14-14-14-34 (XPM II enabled);

Asus nVidia RTX 2080 Dual OC 8GB GDDR6 (2115MHz core, 15800MHz memory, 1.068v);
Samsung nvme m.2 970pro 1TB + Seagate Barracuda compute 6TB;

Corsair HX1000i power supply;

Custom watercooling loop (single loop) on CPU and GPU with 2x 360x45mm radiators.

 

I hope you have any suggestion for this issue. I know it's not a big deal, but it's annoying to see on a high end rig.

Running a similarly high end PC and I'm having the same issue - obviously what brought me here. No issues in game, CPU, GPU etc show no increase in load when the stuttering occurs, but it's there, clear as day. It's almost as if my refresh rate suddenly drops from 180hz to 20 as you say.

 

While writing about refresh rates, a thought occurred to me. I'm now fairly convinced it's a graphics driver issue, at least in my case. I use a Predator X35, which is G-Sync compatible. Once I disable G-Sync, the interruption to the movement of the mouse is resolved, though the start menu animation is certainly not as smooth as it usually is. I wonder if your issue is the same as mine?

I've had this same exact issue with my new computer and it has been driving me insane. I tried everything I could come up with. The start menu was always lagging and when opened it lagged everything, including the mouse cursor. I turned off Windows animations, that stopped the start menu lag but still lagged the mouse.

 

@DiVille your tip solved it, turning off G-sync made the issue disappear. Thank you so much for this. Is there anything to be done about this or what's the next step? Just live with it like this?

 

And thank you @JHack93 for creating this thread
