Questions about G-Sync
I have a G-Sync compatible 120 hz 4K monitor, but since my CPU gets uncomfortably warm playing games in 120 FPS (like jumping between 85 and 100°C) I tend to set the framerate cap to 60 in most games and will probably keep doing that until I've upgraded the cooler.
(And yeah, upgrading the cooler seems to be a necessity, I have dusted out the PC and thermal paste was applied too recently to be in need of replacement etc, cooler is just insufficient for my CPU)

Thing is, whenever I set the FPS to 60 pretty much every game looks really... weird? It's difficult to explain, but there's a kind of janky choppiness going on even though the FPS counter stays a solid 60. It definitely doesn't look like smooth 60 FPS.
From what I understand, this is due to the refresh rate and the FPS not being synced. But isn't G-Sync supposed to take care of that? I have enabled G-Sync for both fullscreen and windowed, but from what I can see it doesn't seem to do anything?
I set both the FPS and refresh rate in-game to 60. Is there something else I need to do? Unless I misremember I also tried setting only the framrate to 60 in a couple games with the same result. I feel like there's something I'm missing here.

have you tried just lowering the refresh rate to 60 in gpu control panel?

Set Dekstop to 2160p / 120Hz

Set NVIDIA color and range to RGB + FULL

Set NVIDIA VSync = Fast

Enable GSync for windowed mode and full screen.

Set NVIDIA Low Latency = Ultra

Set NVIDIA Shader Cache = either 10GB or Unlimited

Disable HDR.

Disable any FPS cap limits.

Which CPU and which cooler? Also which case and how many / what orientation do you have for the case fans? depending on the CPU 100°C is very hot.

What are your temperatures when you have a 60fps frame limiter?

Install CPUz and run the validation and post the result link here so people can see what hardware you have and some of the hardware configurations (e.g. clock speeds, memory speeds, etc.).

You could still be thermal throttling and/or shifting more load to the CPU.

Also install the presentmon utility and use its overlay to watch the frametime graph and the GPU_busy graph to see how your settings are balanced for your hardware. You want the GPU_busy graph to be as close as possible to the frametime graph.

Also, under normal conditions the recommendations badmotha said are pretty sound, other than disabling HDR. If you have a decent HDR display and depending on a games HDR implementation it’s worth using. For games that have trash HDR implementations you can use Windows AutoHDR if you’re running windows 11.

Just note that enable of HDR means all your Monitor presets gets disabled and you won't be able to adjust them or apply one of those whenever HDR is enabled/active.

You can simply take time to manually adjust a Monitor onboard preset to have the best color saturation, hue... brightness, contrast and black level for most gamea and movies. HDR for most part is pointless on PC. It's for lazy people with TVs + game consoles

As you generally would not want HDR on and switch to a different preset as a daily driver for the OS Desktop. HDR can be suitable for movies that's about it

Some displays the gsync/freesync might not even work properly with HDR on

No cpu in games should ever be getting to 100c so must be an issue with the cooler.
My 7700x with a Noctua NH-D15 Chromax cooler will be in the 50's and maybe 60's in high fps games.

Yea Desktops shouldn't get that hot regardless of game performance or FPS. That's more of the norm to see for Laptops. CPU getting above 90*C or GPU gettingabove 80*C something is seriously wrong with your fan curve settings, your coolers, airflow, or perhaps failing fans... blow out a Desktops internals every 3 months or so and it will help avoid those kinds of issues if dust is an issue for you.

Running the monitor at 60hz is why the monitor is janky, so use 120hz and you will notice a big difference.

My monitor is 144hz, but if I get 250fps I’m not capping that, run baby run, haha. I might want to clean my fans, since I seen 91c in COD. I turn the graphics down. So even with good cooling, if you work it, something will heat up.

But, don’t worry about the fps and hz being the same. Keep hz at 120hz and it doesn’t matter if the fps is capped at 60fps. It should be pretty smooth. 80-100fps might be better yet, but depending how high you can go before heating up and if you’re able to get the heat down threw any settings.
