Strange Stutter on 75Hz
My monitor's factory refresh rate is 60Hz, but i overclocked it to 75Hz (dont know whats the proper word for this sry). Every game is working fine, however with black flag, even though the fps counter is at 60-62, I have a strange stutter like the frames are skipping, feels like it runs at 50fps, but it doesn't....i don't know. On 60Hz its perfectly fine, but i dont want to set the refresh rate back every time when i want to play this game.
I know the game is hard capped at 62fps and thats not my problem, but is there any solution for this problem? I never met this before.

Have you disabled Vsync? this game got some big issues with it for some reason.

Ingame Vsync - Off
I enabled Adaptive Vsync and Tripple Buffering in the Nvidia Control Panel.

I am getting stutters as if physx was on as well when I have disabled it. I am on a 1080 Ti. This game is screwed for new hardware.

My monitor is 144 hz and I have set refresh rate to 60 Hz, stutter persists

See? Its really strange, im always getting 60-61fps, but the image is just not smooth as it should be.

Yes the game is internally capped at 61 fps vsync on or off. When I first played and finished the game back in 2014 on my 780 Ti, I had absolutely no stutter. i was playing on a BenQ 120 Hz monitor as well meaning the refresh rate is not the problem here.

Now I have a 1080 Ti and a 144hz monitor which I tried at 120 hz and 60 hz and it made no difference to the stutter.

This leads me to believe its the new hardware. Maybe the game has an issue with the 1000 series GPUs, the 1080 Ti specifically or Nvidia driver.


My framerate will drop to 55 and rapidly climb back up to 61. It is happening every few seconds now on the main hub cities and Greater Inagua. Very frustrating...

Dont use adaptive VSYNC

Use regular

In addition to setting regular vsync, try setting an fps cap of 59 or 60

Triple buffering in NVIDIA control panel or inspector here does nothing as that is only for OPENGL games, Black Flag is DirectX 11, so you can put that back to default
