I am particularly impressed by your replies and screenshots. Despite the artifacts and bugs, It seems promising. I will try on my side later when I will be more available. Just a question about the MFD : I remember when i tried Orbiter with wine and Vulkan, I got huge performance drop with some sophisticated MFDs, especially on XR fleet, and not so on Windows. Do you still have this performance drop with the native version you are testing ?
I can't tell about the MFD, it really depends on which one it is. Maybe it's using GDI instead of sketchpad and wine is having trouble with that, or the D3D emulation is the cause, who can tell... If you're talking about the Map MFD, it's been converted to sketchpad and does not impact performance that much...
