Im not sure
3D interface

I find the chess.com 3D board option to be very poor. After playing 5K games on chess.com during COVID (last 15 months), I was unable to think/comprehend with my recent over the board games. The chess.com 3D graphics are closer to a 2D image than they are a real over the board perspective.
I was wondering if there are any programs/apps/gui that have better 3D graphics and can interface with chess.com to use those graphics.
There are no other interfaces that you can use. The site doesn't support anything but the live interface, the apps, and some e-boards.
Are you using the Real 3D board?

Not sure what you mean by Real 3D board. In the settings area for Board & Pieces I have selected 3D Staunton.
