My sim includes the RealSimGear G1000 suite. In order to get it to work, I've been using Cirrus version 1.2.0 with the 3D cockpit camera moved up, so it appears I'm looking out over the glareshield, just as you suggested back in August 2020. However, doing this cuts down the field of view very substantially, and I don't like that.
I'd really like to use the RSG Suite with the "Forward with No Display" view, the way I can with the Laminar Cessna 172. You explained why that couldn't be done, back in 2020. Have you figured out a workaround yet, and if so, is it in version 1.3?
