I will ignore.
4K is 4 monitors, not 3 1080p monitors.
Is healthy in general to change your point of view when is proven wrong.

You can clearly see that the image is just the same (in terms of FoV), when only the resolution changes, but the aspect ration and FoV in game stay the same. That is why when moving from 16:9 1080p to 16:9 4k (or even back to 16:9 1280x720), only the density of the pixels change. That is why when you activate DLSS, Fidelity FX or any other in game personal resolution scale, only the resolution changes, not the FoV.

Look at CPU3 in all pictures, that thread is almost maxed out at 90%+ both in 1080p and 720p. Once the extra FoV is increased (due to the extra screen - 3 in total), the FPS drops because the CPU was already maxed out in normal 16:9, 100FoV in game set (poorly threaded game, although a Vulkan one), so extra work is needed now for maintaining the same FPS... which cannot be done, ergo lower performance.
So, going wider from 16:9, you'll need extra CPU power, in which case, the old "the higher the res, the less important the CPU becomes", is not always true. The demand of a more powerful CPU increases with FoV.
