The framerate issue going above 60fps seems to be fixed for monitors that are capable of going past 60.
Released!
Although Apoapsis has been out for over a month, it is finally here on Steam!
Just because this game is "done" doesn't mean it won't be improved upon. I have a list of fixes on the storefront page. Feel free to add to the list of fixes.
-For whatever reason, I had to use a frame limiter like RivaTuner to cap my framerate to 60. Not sure why, the game scales with GPU framerate!
