I haven’t played the game in a few years, and decided to give it a go. Everything seems fine except that ship movement is surprisingly slow and jittery. The game is playable, the graphics are perfectly fine no matter what settings I choose, but the ships move so slowly that it can take minutes to pass a turn.
In the linked video I start a new game with default settings on a tiny map, and simply move the starting exploration ship. It takes 10 seconds to start the game from the main menu, and 20 seconds for the ship to finish moving. Notice in the video that the other animations are not slow: the moon orbits the Earth smoothly, the Earth turns on its axis smoothly, etc.
Can anyone offer any advice? This is a fresh install of version 4.21 of the game, and there are no errors shown in the debug.err file. I am running Fedora 34 with kernel version 5.16.9-100. Steam is using the default Proton compatibility layer, though I tried several older versions with no improvement. My cpu is an AMD Ryzen 7 5800X, I have 64GB of ram, and my graphics card is an NVIDIA GeForce GTX 980 Ti.
