Hi, just started using the program. It works well for 2D but the rendering in 3D is almost unusable. If I built a wall then the 3D almost disappears. Also the controls for 3D are very slow. I am using win 10, core i3, 8G memory and there should be no reason to be slow. I used a similar app which other issues but not rendering was very fast. Thank you for any suggestions.
