My game is blocked on 62 fps,sometimes he drop on ~40 fps with a laggy visual. My game turn in 64bit version, for me any differance with the 32 bits version, i don't have a OpenGL version. I have turn off Vsync, Triple Buffering and turn on the threaded optimisation. I have run starbound without steam, without steam overlay, in administrator, in compatibility mode. The game have already 62 fps no amelioration, no difference. My config is : W10 anniversary update, I5 6300HQ, 8GB DDR4, GTX 960M. i use just a traduction french mod, i play in full screen 1920x1080 with disable display scaling on High DPI settings.
