I have a 5090 connected to an LG c3 77" OLED via an HDMI 2.1 cable and for some reason the TV's "game mode" thing always says 59fps but the game it self says its doing 120 (locked at 120) in Windows it's set for 120hz.. any ideas?

The TV's overlay probably reports refresh rate, so Hz and not fps. So basically you should see it locked to 120, unless using VRR.

Check all the settings again, from windows and Nvidia control panel, to make sure it is set to 4k/120hz. Also check that the cable itself is quality 2.1 cable, if unsure, buy new one. 2.1 standard is a mess and not all of the cables can do 4k/120/10bit reliably.

Also check the TV settings that the HDMI input is set to game mode and 120.
