[SOLVED] Please help me, stuck at 30Hz

[Pijmzhchus]

I have a problem with gaming on my Samsung TV (Q55Q70R). I can get to 1080p 120Hz at desktop and I know it works because the cursor is smooth and when I check it on TV itself it shows 1920x1080 / 120p. But when I turn on Red Dead 2 specifically the TV puts itself to 1080p 30Hz mode. Other games seem to work fine. What's weird is that it shows 120Hz in games graphics menu that 120Hz is turned on but when I turn on Vsync the game locks to 30fps. I would really appreciate your help!

I updated graphics driver, restarted and now it works @ 120Hz! Can't believe it.
