Bug/Issue Game blocked on 62 fps with drop

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.

 

Hi there. To be honest, 62 and 40 fps are both good refresh rates.
Under 30 would be bad, but you seem just a bit... "PC-Master-Racy"?

If there is no "real" issue, like texture- or loading-bugs, I'm afraid I can just advise you to play on better hardware.

 

yes but for a game like starbound before 1.0 i have better than 62fps

 

Quite some stuff changed before 1.0 was released.
Performance dropped for a lot of people.

 

it will be fix?

 

Can't say that.
But I guess we can except at least some optimization in the next few updates.
