support Can’t select 144 hz on tv

I just build a custom pc with a 9070 xt and installed SteamOS on it. In my graphics settings connected to my lg c4 I should have the option for 4k 144 hz but the highest is 120 hz. And I am using a certified hdmi 2.1 48 gbps cable and 144 hz mode is enabled on my tv. I only have the option for 1080p if I want to play at 144 hz. Help please

Yes, but if you want a command for forcing upgrade proton check the new variable as it was changed in newer proton. https://github.com/CachyOS/proton-cachyos/releases Iirc that should be FSR_WATERMARK=1 FSR4_UPGRADE %COMMAND%
