Anyone else get very noticable mouse lag in the nvidia overlay?

Whenever I use the "Alt + Z" function to bring up the nvidia overlay, my mouse feels very off.

Is this a common thing, it's very noticeable, it's comparable to what my mouse feels like in the bios; very sluggish, delayed, and twitchy.

Similar issue here. I have no mouse acceleration or smoothing set in Windows, I have a flat linear connection between mouse and cursor and that's what I'm used to. For some reason when I press Alt+Z to use Nvidia's In-Game Overlay, my mouse is accelerating all over the place and it's very jarring. Did you find a fix or yet, LLm1? Or any info?

My mouse doesn't change at all when I open the overlay.

Have you got the experimental features box ticked? That caused me problems so I had to turn that off, worth a try if you have it on.

Overlays by any software will often add temporary input lag while the overlay is up. This is normal especially during VRR/VSYNC ON. There is a lot less impact during VSYNC OFF.

This is caused by a potential combination of:
- Compositing latency (like Windows desktop versus FSE, even if you're still in FSE)
- VSYNC-miss latency, possibly caused by compositing latency
- Temporary framerate cap that occurs (this is common)

This will be much worse lag at 60Hz-144Hz, and much less lag at 240Hz-360Hz. Fast GPUs on VSYNC OFF, the lag may not be noticeable at all.

Alas, this is normal, just make sure you dismiss overlays to eliminate this latency.
