** Not Resolved **. This is a re-post of my problem. My previous post was sent to "Resolved" after another user provided some advice. Unfortunately their advice did not solve my problem.

Since around Patch 2.16 (or whichever patch occurred around the release of the initial PS4 beta) I have had stuttering. This occurs when the game is at an average 60 frames per second.

The stutter is persistent when running in Full Screen. When running in Border-less Windowed the game will run stutter free for a period of time, before going into a pulsating graphics stutter (about ~10 stutters every second) which doesn't go away until I switch windowed -> full screen -> windowed.

Windowed mode has always been like this for me. It is only recently that Full Screen mode became a problem.

My specifications are:

CPU: i7-4770k
GPU: GTX770 (using latest stable Nvidia drivers)
RAM: 16GB DDR3
OS: Windows 8

Thank you for your help! Please let me know if this is a known issue.
