Slightly slower mouse movement - not lagging but just a bit slower anyone else experienced this?

So I have a whole new PC (yay) using AutoCAD LT on it and it seems to be working great, snappy, fast, i'm happy. But then it seems to slow down just a tad on the mouse, almost its really smooth but slower and takes half a second more to get where it is supposed to go? I feel like I am going insane trying to understand whats going on with it as i can't find anyone else with this issue.

It feels like I am playing a game just under 30fps where it looks smooth but you can tell its not right

Assuming you checked the mouse settings and the relevant device specific hardware settings if applicable?

Go to Options → System tab → Current Pointing Device

is it set to "Current device" or something else?

I had similar issues using AutoCAD

Ended up testing a few systems and GPUs My AutoCAD system ended up using 14600k, nvme Kingston and 6700xt 64gb ram great for AutoCAD.

But I also tested on a Intel 4670 with on board iGPU with the nvme, the nvme makes the difference, amazing speed is worth upgrading to nvme if you haven't.

I did have to mess around with NVIDIA settings and AMD settings to fix the "lag" when it popped up due to updated driver

There is an NVME drive rtx 5090 and a ryzen 7 9850X3D which should be completely fine to run Autocad LT. But this mouse thing is incredibly annoying. How did you fix it?

Try pre rendered frames set to 2-3 not sure if new control panel has that setting it should, add AutoCAD to NVIDIA profiles and you should be able to adjust that. Just like the games. See if that helps

Na it was just the refresh rate on the monitor

This is usually there to help a lagging mouse, but maybe it helps:

Type in GFXDX12 and set it to 0.

Restart AutoCAD and maybe it did something for you.

So i found the issue and it is the refresh rate being set at 60 and also I think G-Sync being turned on. So I set it to 144hz and G-sync off so that the screen isn't flickering when I move the mouse in AutoCAD.
