Playtest direction on the canvas layout: all five MFDs at the compact 320x240 glass size - upper pair pushed to the top corners, score glass top-center, lower pair in the bottom corners, map bottom-center - and the viewscreen now fills the entire 1920x1080 canvas. Launched with -res 1920 1080 the 3D renders native 1:1 (the 2007 D3D9 path takes the 1080p backbuffer and 16:9 aspect without complaint). start-windowed.bat updated accordingly. Verified live: full-screen native 3D with the cockpit floating over its edges, mission running, preset lamp lit on the map column. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
