Issue with some games at fullscreen

[5haunJN]

When running games at fullscreen (borderless fullscreen) the games refresh rate caps at around 30hz, but when playing windowed, it caps at the fps cap in game. The game I have the issue with is Final Fantasy 7 Remake (and some other games). Here is the issue in action: https://www.youtube.com/watch?v=eQYhyykq4Do
The video does show sunshine with VDD, but I've uninstalled both and installed Apollo with sadly the same issue.

Running on Windows 24H2 and have Windowed Optimization on and HAGS disabled.

Sadly it's a game issue that Apollo cannot help. Maybe there're mods that can fix this problem?
