Before the Dune update the Navigraph Chart panel impact on VR performance was negligible (1 FPS?). Yesterday it was consuming half of the FPS on 4090 and Ryzen 7800x3D (drop from 40+ to 20+).
I will check with the most current version of the panel.
My hypothesis: Asobo broke the ability for the panel to recognize if it works in VR or 2D. This triggers scaling issue. Maybe the panel now work in VR in massive resolution which triggers FPS drop.
