Im using a benq zowie 240 hz monitor, mother board is asus prime z790-P WIFI and bios version is 1666 and yes i have tried g sync and it doesnt really make a difference, adds a lot of input lag and smoothness barely improves
I personally have an ASUS z790-v ax w/ bios version 1663 now after downgrading from version 1664(as I could not disable C1E) My CPU is the i9-12900k @ 5.2ghz P cores - enabled, E cores - disabled, Hyperthreading - ON, C-states disabled. My advise would be to downgrade from bios 1666 to bios 1663 which will allow to disable Core Parking and you have a CPU that can be OC'd to ~5.5ghz w/ e-cores disabled. I only play CS2 and I was curious to know which FPS game you play.
I did the same thing by not reading the text I have bolded below when I foolishly updated my bios.

"1. Updated with Intel microcode 0x12B to address elevated voltage requests during idle or light activity, further mitigating Vmin Shift instability issues.
2.
The option to disable C1E in the BIOS has been removed to ensure it remains enabled, reducing processor stress and maintaining stability per Intel's recommendation."
