The instrument panel is too dark at certain angles to the sun. Even going toward the sun, the panel should not be so dark you can't tell what the gauges are showing. I have worked with gamma, results were not good. Thank you.
What planes, specifically, are you seeing this? I don't think it's bad, but I don't fly every plane. One of the post effects that I think make a big difference (in case you want some of the effects active) is bloom.
Sounds kind of like real life.
IRL you have instrument lights you can turn on, and we should be able to do that here also.
I've got an older system by today's standards that still runs the game well by my standards.
