120hz not working on Series S/X

I had thought they had optimized and updated the game for 120hz? I see no options when I boot the game up and even though at the dashboard my monitor is at 120hz when I boot MCC up it’s always 60 even in gameplay

Anyone know what’s up?


Thanks but its not a hdmi 2.1 issue. I believe it has to do with Xbox forcing 4k signal for HDR. When I turned Allow 4k off I lost HDR but now 120hz is working on MCC. My monitor is 1440p but it accepts a 4k signal. Looks like an issue on the Xbox system level I suppose.
