Just tying to help you out to improve the game.
I have 4K monitor, 16G, NVIDIA GTX 1080 8G, and intel I7.
1. Just started a game, and very often in menu mouse cursor resets it's position and moves to the center on the screen. I think it happens when I move mouse pretty fast (like normal). If I move mouse very slow, I do not see an issue.
2. While I am on the first station, if I turn my head around with mouse (first person view), often my head move freezes and looks like mouse does not work for 1-2 seconds. FPS drops on ~5 FPS in the time., It does not matter where I am looking on or if any ships fly around, just random mouse traction loses. Probably, the same issue with #1.
About FPS. I have 42-38 FPS while I am walking on the first station, but as soon as I go inside of transportation room with big while "door" or something and pin pad where I can select travel destination, my FPS drops up to 25. Have no idea what kind of math logic you use here but this drop is weird

Let me know if you need anything else like logs or hardware specs.
