So after some testing with the new release of AutoCAD 2022, I noticed a small issue where the mouse response seems to be slow or lagging.
After some investigation, I noticed this only seemed to be an issue for certain machines with certain graphics cards. Running some troubleshooting on this I found the issue only occurred when the graphics card was using DirectX 12, which was introduced in AutoCAD 2022.
The good news is this only affect a small number of graphics cards/drivers, and Autodesk is already aware and working towards a solution. Even better news is, there is a simply workaround for now.
To temporarily fix this, enter the new AutoCAD 2022 System Variable into the command line:
GFXDX12 and set it to 0
This will revert to DX11 on restart of AutoCAD.
Alternatively, you can use the following Autodesk article to revert AutoCAD 2022 to use DX11:
