Updated preview screenshots are visible on the Facebook page of the publisher Just Flight, for all simmers interested in the Concorde project, in development by DC-Designs.

This is a P3D and MSFS project. Just Flight confirmed again in the comments that this add-on is a high-quality aircraft with custom coded animations and systems, but less demanding than other study-level airliners, to remain accessible to all simmers.

I would remind you that in a previous presentation, the developers themselves had also indicated that it will still be necessary to respect the fuel transfers, the different steps climb before being able to actually reach Mach 2.
