Game looks amazing! I love all the little details like the vapor cone when you break sound barrier.
The FPS count is high on highest detail settings and 1920x1080 res it looks like this on my PC (i5 6600K 3,5GHz, GTX970 4GB VRAM,16GB DDR4 RAM).
The new cockpit and music and voice-overs are great and adds new quality to your game. The difficulty could be lowered however. I got my ass kicked several times now ☺
