Yep I know this still needs further tuning so don't jump on me please, but as feedback it does just look look like brightness and contrast turned up, inside the cockpit does make the instruments look more readable, the roundel on the wing looks a lot worse ... also there seems to be a big drop in FPS in the first comparison shot, but no real difference in the other ones.
Screen shots are one thing but seeing things in motion on your own screen are another too I guess.
But I'll leave final judgement until its tweaked.
Good to hear about the sound overhaul, one of the things I was looking forward to was hearing the sound of the Merlin engines in particular, there are lots of examples of the merlin sound in the public domain from various airshows ETC.
After this they really need to address some very outstanding issues though like the radio communication commands.
But good to see more progress
