Hi 33lima, found it in the game's code. BOB2 doesn't save your resolution as numbers, it saves it as a position in the display mode list. Every wrapper config change reshuffles that list, and when the saved position no longer matches, the game quietly drops back to 1024x768. That's your low res 3D, and it's why each experiment seemed to undo the last one.
The fix, in this order. First update to v1.7.2: delete the old BOB2-Win11-Fix folder, extract the new one, run Install and repair, and press Fix on anything it flags. Then delete C:\Users\your name\AppData\Roaming\dgVoodoo. Start the game and re-select 1920x1080 at 60 in the GFX options for both 3D Resolution and Campaign Resolution, even though they already look selected. Quit properly, then fly on the next start. After that, leave the dgVoodoo control panel and config alone, as any change there invalidates the selection again.
