Locked at 48fps on windowed

[Makusensu]

Hi,

I'm using a 120hz display which have 2 working rate modes: 48 and 120hz.

While there is no problem to play 120fps in fullscreen, when I switch to borderless or windowed, the game locks to 48fps.

Is there any workaround to force the game works at 120hz, or the possibility to add an option to independently set the refresh rate in settings?

This is a laptop based on i7-9750H UHD Graphics 630 and GTX 1660 Ti.
According to dxdiag the video output pass by the Intel UHD.

Current Mode: 1920 x 1080 (32 bit) (120Hz)
Native Mode: 1920 x 1080(p) (120.035Hz)
Output Type: Internal

Thanks


Edit: After checked Intel control panel was correctly set to 120hz.
I found that there is like a bug when you change the FPS setting in game, only when you are running windowed.

The fps is not reflecting the actual option set in the menu under uncapped or 120fps. (The variation is not due to engine charge, I was in isolated place)
