I really wish they would fix the dV calculating in the VAB. So that all stages show dV and also TWR on other bodies. Oh and the antialiasing is horrible for some reason. I get good performance but I rarely play because the UI is so cumbersome. The game by itself looks good you can fly around and explore. The game makes it somewhat harder to do which is a pity.
Im not a gentoo user but this is the most accurate visualisation of my first Linux experince ca 23 years ago.
