I tried Bricscad, we are using point clouds almost in each projects, and Bricscad is not performing very well with laser scans, I hope it will be better in future.
Anyway, I tested once again Autocad 2023 new 3d feature. For now, point clouds are not supported with that visual style which is again not good for us. You cannot change background color and adjust style at all. Hope it will be improved in future also.
I created one video so you can see 3D performance:
