Hi, so I have an issue that when scrubbing through clips and importing them ni timeline or basically doing any intensive task in Resolve lags my mouse cursor every few seconds. Playback works smooth, only the mouse lags a lot. It is super annoying and I don't know what to do. Can anyone help?

I have DaVinci Resolve Studio 17 Beta 8 (but I noticed the issue on Beta 6 already). The lag is present on all my projects on different types of footage.

I actually have the issue since I built my new computer few weeks ago. It is Ryzen 5900x 12-core, 64GB RAM, NVIDIA GeForce RTX3090 (with the latest NVIDIA studio driver), 1TB M.2 SSD PCIe 4.0 for the system. I run Windows 10 Home 64-bit. My database is on the system SSD and my footage either on NAS with 10Gb connection or on another SATA SSD.

I use wireless mouse and keyboard combo from Logitech. Tried USB cable mouse and there is no difference though. I also read that the issue can be caused by G Sync, but I don't have a G Sync monitor. I have a simple UHD 60Hz LG screen.

I would appreciate any advice.

This isn't commonly reported.

Did you try wired mouse and keyboard? No wireless?

I had the same issue on 17.1 version, Big Sur.

I just have installed the 16.2 version
It work smooth.

BUT this version can't support Braw 2.0, so we have to find 16.3.2 beta, that is not yet on the "latest download" page

Did you fix your problem ? I don't.

Mouse lag when I set color wheels, or when I move a nods.
Impossible to find 16.3 beta version...

I have been having the same issues. I have the same specs as OP except I have a 3080.

I have tried resolve 16 but still get mouse Lag.

I do have a gsync monitor but have disabled it both in windows and on the monitor and still get mouse lag.

I have installed the nvidia Studio drivers and noticed that resolve runs overall much smoother but I still get mouse lag.

I have reinstalled windows and still get mouse lag.

I am assuming that it has to do something with the new hardware since I have seen a lot of people complaining about this with the new hardware.

The drivers are maybe not the solution. Hardware is old.
I'm on a macbook pro mid 2014, with the latest OS (big sur), using the trackpad and internal files with SSD.

The problem happen only when I edit raw files, in the nod or color wheels.

ProPres work smooth
