VRR on new monitor

[BrzI]

Hi folks,

just bought a new LG C5 monitor. I have enabled VRR and it works fine on MSFS 2024 and EA F1 2024...you can clearly see the refresh rate indicator going between 40 and 120 Hz. Using an AMD GPU (RX 7900 XTX).

However, in DCS it is stuck at 59-60 FPS as shown in LG game optimizer dashboard. I have disabled vsync but no luck.

Would anybody have any suggestions ?

Thanks
