Those recommended settings on reddit say to turn off AMD freesync premium if using nvidia..
excerpt from the settings I put in quotes in my previous comment:
LG TV
=========
PC mode: On
HDMI Ultra Deep Color: On
Reduce Blue Light/Eye Comfort Mode: off
Aspect Ratio: original
Just Scan: On
Energy Saving Step: Off
AMD Freesync Premium: Off (or AMD/XSX = on)
[CX] Instant Game Response (ALLM+VRR) = on
[C1/C2] VRR & G-SYNC = on
[C1/C2] Game Optimizer (ALLM): on
[C1/C2] Game Genre: Standard
Fine Tune Dark Areas: 0 or (-3 to -5)
I don't know if it would have a detrimental effect or matter but that write up of recommended settings is pretty thorough and reviewed and honed by comments from others in the thread. The recommended settings say to turn it off when using a nvidia gpu and on for amd/xboxseriesx. According to the footnotes there:
"Enabling AMD FreeSync Premium will force XSX/Adrenalin to use FreeSync over HDMi instead of HDMI Forum VRR."

Named PC hdmi input
=====================
You have to go into the home settings and edit the named input ICON itself, not just the name of the hdmi input, to PC in order to get RGB~444 chroma. If the hdmi cable ever loses connection it can revert back out of PC mode which will compromise text making it look tattered on the edges and will also be detrimental to a lesser degree on graphics fidelity so keep an eye out for that.

Picture Mode:
==============
As for the picture mode, Game Optimizer or HDR game Optimizer (C1) or Game Mode (CX) will remove processing so that you will get the least input lag -
- but to me, as long as you have all of the interpolation and any other enhancement settings manually turned off on the mode, the other headings are usable in games. The most likely scenario is using most of the other modes for movies and vids and a dim mode - so I'd only zero one other heading extended features wise and customize it for an alternate "game mode" for testing purposes settings wise.
Instant game response should override other modes and swap it to the actual game mode automatically anyway initially though, and back when out of the game, if you have that enabled on the hdmi input (see next image below). I use HDMI eARC out which I think is still incompatible with instant game response hdmi auto-sensing - so most of the time I keep my PC rig's 48CX PC hdmi input on game mode manually and leave it there. If I want to watch movies/vids fullscreen rather than in a desktop window I'll switch to my nvidia shield hdmi input via the remote, with non-game picture modes used on that input. You can also use the web OS with youtube, netflix, amazon video, emby/plex , etc. I think the WebOS will be considered a different input like a whole new hdmi input with it's own picture mode settings.
Any of the named settings can be customized so you can make them your own for whatever kind of material you want them to be used for. They are just a good starting point but you can zero every single heading within any of them and start over if you wanted to. For example, I changed a lot of the vivid settings so it's not extreme nor dynamic. I use vivid mode for anime/cell-shaded video material that I still want to have a little more pop/saturation on along with different motion interpolation settings for it's low frame rate animation (which otherwise can cause some weird artifacts). I use APS as a dim screen usage scenario and a few other picture modes for movies, bright room, dark room. Note that the HDR and DV picture modes won't show up for editing unless you are running that material on the TV at the time.
Some people complain that game mode is dull and lifeless (un-saturated color wise). I just turn up the color saturation in the extended color settings on that game picture mode considerably to make it more vivid. [While in Game Picture mode: Picture -> Picture Mode Settings (press pointer on the heading) --> Color slider]. I can further adjust more or temper it down to less on a per game basis using reshade or nvidia freestyle until it looks great for that particular game style. So I keep the OSD's game mode color setting slightly high as a starting point. That is for SDR games. HDR/DV has it's own scale of color volume that kicks in automatically (and is well saturated and luminous) so it's not necessary for HDR games. My color setting adjustment is ignored by them as it switches to a different HDR gaming picture mode automatically when playing those games.

From RTings review of the C1:
"
The LG C1 has a very low input lag as long as it's in 'Game Optimizer' mode. For low input lag with chroma 4:4:4, the input icon has to be changed to 'PC'.
There's a new setting for 2021 models found in the Game Optimizer menu, called Prevent Input Delay. There are two options: 'Standard' and 'Boost'. We ran several input lag tests and found that the 'Boost' setting consistently lowers the input lag by about 3 ms when the TV is running 60Hz compared to the LG CX OLED. It works by sending a 120Hz signal to refresh the screen more frequently, meaning it doesn't affect 120Hz input lag. The published results are what we measured using the 'Boost' setting. On 'Standard', we measured 13.1 ms for 1080p @ 60Hz, 13.4 ms for 1440p @ 60Hz, and 13.0 ms for 4k @ 60Hz."
<Edit by elvn>: According to HDTVtest videos you shouldn't enable the boost settings unless using 60hz games/consoles because it can actually make the lag worse for 120hz gaming. It's basically duplicating the 60fpsHz frames into the 120fpsHz range.
Rtings on CX:
"The LG CX Series has really low input lag in Game Mode, and it stays low with VRR enabled, which is great for gaming. It also stays low with a 4k resolution, which makes it a good choice for Xbox One X or PS4 Pro owners."
1080p with Variable Refresh Rate
5.9 ms
1440p with VRR
6.2 ms
4k with VRR

HGiG / CRU
===========
"HGiG tone maps to actual max TML of panel and will most accurately display a tone mapping curve set in-game or on system level."
"For Windows 11, you can use CRU to set tone mapping curve [Edit.. CTA-861 > HDR Static Metadata], otherwise Windows uses maxTML/maxFFTML/minTML 1499/999/0 nits. Quickly toggle HDR in Windows 11 using Win+Alt+B. "
Auto HDR (Windows 11/XSX) converts applicable SDR games to HDR10. (edit by elvn: sort-of. It ends up with a % of the highlights, not full HDR range)
DTM Off tone maps to maxTML 4000nits.
DTM On tone maps on a per frame basis. <---- (edit by elvn: the regular DTM, rather than HGiG, is guesswork/interpolation so it does so inaccurately, causing greater compression on the top end which loses color gradations/details and could cause side effects (perhaps even banding)).
Dolby Vision for gaming enables native DV games and converts all HDR10 games to DV set in-game maxTML to 1000nits.
