System Information

Operating system:	Windows 10
Graphics card:	`EVGA RTX 2080TI`
	Also seen in a `GeForce GTX 1070 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.67`
CPU:	AMD RYZEN 9 3950X 16-Core Processor, 3500 Mhz

Blender Version
Broken: version: 2.83.2, branch: master, commit date: 2020-07-09 05:50, hash: 239fbf7d93
Worked: It has worked before (but the version has not been informed yet)

Short description of error
This is a very minor glitch but I still find it very jarring.
When I move the mouse around the UI it is really choppy, looks like the mouse is moving at around 24 - 30 FPS.
but if I do anything else like, moving/scale objects panning camera I am getting a 165FPS smooth experience.
It was like this in 2.83. Its not a problem I can still use Blender but it feels like quite a choppy experience seeing you are moving your mouse around half of the time.

Exact steps for others to reproduce the error
Literally start a new project or open one , its always laggy

Thanks for the report. This seems to be a graphic driver issue (since the UI uses immediate mode for drawing).
Please double-check if the drivers are up to date.
To upgrade to the latest driver, see here for more information: https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

I just noticed this is happening in very few programs so this isnt a Blender specific issue, however I cant find out how to resolve this. I am already updated to the latest software on my 2080TI

I just found the issue, in the NVIDIA Control Panel, I just clicked enable G Sync in full screen mode and it is completely fine. For anyone else that suffers the same issue.
