VSYNC Limiting FPS to wrong value

I'm experiencing a strange issue and I'm wondering if anyone has any insight.

I have recently built a PC with the following: MSI B550A-PRO, AMD 5600x, 16GB @3600Mhz DDR4, XFX 6600XT, 1TB NVME, WIN 10 21H2

I also have a 75hz FREESYNC monitor (Lenovo L27q-30) connected by a HDMI cable to the GPU.

Monitor drivers are installed. GPU Drivers are 2021.12.1

The issue is that the two games I've tested so far (GTA V and AC: Origins). Following the recommended use guide (https://www.amd.com/en/technologies/free-sync-settings) for FREESYNC, as well as countless guides online (and the way I have it set up on my old build), I have enabled VSYNC in both games, and set the fps limit to 72 (AMD Chill).

The problem is that the games are limited by VSYNC to 48FPS which is my monitors' lower FREESYNC range (48Hz-75Hz) instead of it being limited to 75 which is my monitors' upper FREESYNC range (or the 72 FPS limit in this case). This is fixed by entering the game settings, setting the refresh rate to 60Hz, and then setting it back to 75Hz. After that, the VSYNC limit works as expected.

I have to do this every time I start either of the games - hence this post. If I completely disable FREESYNC in AMD Settings, the issue does not manifest and instead the games work normally at 75Hz.

A workaround I found so far, is to just disable VSYNC completely in all games, and use FREESYNC with Enhanced Sync enabled in AMD Settings. This seems to be the best solution this far, but I would still like to know why VSYNC in both games treats the lower FREESYNC range as the actual refresh rate of the monitor.

I don't have Vsync enabled in games..

Just use Freesync and Enhanced sync as your doing now.. Vsync will always drop your framerate..
