Maybe some of you has an idea: I have a new Surface Pro 3 with a native resolution of 2160x1440 (which is supported by KSP), which is an aspect ratio of 3:2. Nevertheless to improve performance I usually play in much lower resolution such as 1280x800, which is not exactly 3:2, but a bit more. When going on full screen, it is playable, but planets are not exact round any more (more in a Kerbalish way of being round). Any idea, how I could have a full screen game, but with lower resolution and then (obviously) some black areas (either left/right or up/down) to keep the right aspect ratio? Thanks and happy new year!
