As someone who flies aircraft with mirrors and multi-function displays such as the F/A-18, AV-8B, and soon the F-15E, I would like to suggest something.
In the settings, you have "Res. of Cockpit Displays", which controls the resolution of the MFDs' image quality and cockpit mirrors. Personally, even though it decreases performance, I like to use my mirrors, but if I want to reduce the MFD resolution to have a more realistic LITENING image, my mirrors will also have their resolution halved.
Since it's something simple and the F-15E is very close, I think it'd be a good idea to make a setting "Res. of Cockpit Mirrors" and change "Res. of Cockpit Displays" to only affect the MFDs.
