Hey, so after a while I figured it out:

Razer does not provide a SW for their mouses for lates macos. But theres a open source program called Razer macOS, which you can download. This program allows you to setup LED lights, but also DPI and Polling rate. I found out that from some reason in Autocad LT, the higher the polling rate you setup the worse performance from the cursor you get. So if you set up Polling rate in Razer macOS app to 125 or similar (lowest) the performance of the cursor gets way better.

Hope it helps.
