Saw Linus Techtips review on Alderlake and he mentioned this fact with MSFS.
Not quite sure why you think the sim’s performance is throttled by one processor, especially when we can get fps in the 50s on ultra settings with the same graphics card as the OP has (2070s). Sure, maybe some more optimization could give a few more fps, but does it really matter, when it already can deliver as much as it does?

75 deg C is fine and really your GPU will be obsolete ( already is) well before you damage it through 75Deg C , enjoy it!

That is normal. As others have said - as long as cooling is good the GPU will be happy. Remember they are designed for this and dont forget how the miners beat the word not allowed out of them - and they still keep going!

Not only it’s normal, you want your GPU to be at 100% utilization. It means your CPU is able to keep up with the full potential that your GPU can bring to the table. If your GPU utilization falls, it means there is a bottleneck in your system and the GPU is waiting for your system to feed more frames to render.

The one thing you don’t want is the GPU not being used to it’s fullest because it’s probably waiting on the CPU to give it stuff to work on so in that situation it’s CPU limited.
But also, people keep seeing the low CPU TOTAL usage and think the sim doesn’t need and ask for more, that’s not how it works, please look at all the cores and you will see depending on how many cores you have some won’t be doing much and what they are doing is more to do with Windows than the sim and others will be topping out. If the sim was coded to use more cores than that the total usage number may go up, or it will just run better, but it can’t as it’s stuck only being able to use SOME of the CPU.

I wish my cpu was pegged at 100% (with pop out instruments)… EDIT: I meant to say GPU! Might have been a case of keyboard autocorrect.
Not a good idea… 100% means the CPU is THE bottleneck, not just for MSFS but for everything running. 100% CPU will starve the GPU and FPS drops. Actually, if the GPU is at or near 100% it means that the GPU is pushing out maximum FPS based on the graphics settings.
No need to go easy on the GPU (or CPU for that matter)! It is built to be maxed out. 75°C is completely normal for a GPU (and nowadays even for some CPUs). Conciderations about lifetime due to thermal load are irrelevant for those consumer products. Also modern CPUs and GPUs have protection against over-temperature. It is extremely unlikely, that you fry your GPU with too high settings - the worst you can expect is a crash.
I’m going to guess that you didn’t read the post that I linked. I’m at <25% GPU usage and 10% CPU usage with pop out instruments. I’m nowhere near becoming CPU or GPU bound.
EDIT: LOL!! I think I had a typo! I meant to say GPU in that previous post!! But the point is that the sim isn’t using the hardware anywhere near its potential with pop out windows.

Makes sense with a typo. I have decreased performance when one window is opened. The system crawls almost to a stop when two windows are opened. I’ve experimented increasing the sim rate. Using 16x in the sky is too fast for my CPU/GPU because frame rate drops to 5 to 7 FPS.
Without popouts, my CPU is running near 100% on the main thread. WHether I’m main thread or GPU limited depends on my graphics settings. But I can easly push myself to the spot where it’s alternating between GPU and CPU limitations and both main thread and GPU are near 100% usage.
With popout, my main thread drops to about 60-70% usage at most (sometimes less than 50%), and then I’m permanently CPU bound. My GPU (RTX 2080) never sees above 70% use regardless of my graphics settings.
I should take the same set of screenshots looking at CPU per thread usage. From what I recall in the past, no thread is ever pegged at 100%. It actually looks like a vertically offset square wave going between maybe 40 to 80%. And I remember looking to see if the load was being transferred to another thread as the first one dropped down to take up the slack. It didn’t seem to do that, which is curious.
My main thread hovers near 100% without popouts. That gives me quite nice performance overall. With popouts though, I’m immediately thread limited despite my main thread rarely exceeding 70% usage.
