I work from home and I work for an Civil Engineering company that uses Civil 3D. At the time i built my home workstation, I could only get my hands on a Radeon RX 6800 xt. I have experienced some strange behavior with pull downs to select things, and some graphical issues. I should clarify that i have 2 32" 4k screens and one 32" 2K screen. I am curious what others have done and what your experiences have been like using Autodesk Civil 3D software using a Radeon GPU, ;and if you have found a way to make it work with Civil 3d.
Thanks,
