Hey guys, I also returned to the game after a fairly long hiatus, and after upgrading to a new PC, I am also experiencing the same issue. I have encountered low fps when running fullscreen on my GPU, and my idle percentage is zero or close to zero at all times. I am using an nVidia 860M GPU, and also have integrated graphics on board via an i7. I have attempted many of the solutions already offered here on the forum, including running x64 java, allocating more memory, checking that my nVidia GPU is running the game and not the integrated graphics, running in windowed and borderless windowed, disabling Aero themes, disabling dpi scaling, disabling vSync, and checking AA settings on my card. So far, the only two solutions that have made a noticeable difference in the performance of the game are running in windowed (not borderless windowed) with a custom resolution and running the game on my integrated graphics as opposed to the 860M. I've chosen the latter as the lesser of two evils, since I can still run in full screen at 60 fps without any serious issues, but it most likely provides a lower performance ceiling than I would encounter using my graphics card. I just wanted to inform others that this issue can be reproduced, and that there is another temporary solution (running on integrated graphics). I suspect this is a result of sub-optimal interaction between nVidia hardware/drivers and Starsector, and from a development standpoint its unclear whether this is the dev team's issue to fix, but I would appreciate any attention and help that can be directed to the matter. Thanks!
