You have the same screenshot twice in your post and it’s unclear what point you’re trying to make.
Either way, a general statement that will apply is that XPlane is not the same as FS2020 from a graphical fidelity standpoint to streaming global textures to other things such as live weather/traffic, etc.
If you’re happy with the features and functionality that XPlane offers on your hardware, it’s right there for you to use.
If you’re not happy with FS2020 then you can either tweak the plethora of settings available to you to get the performance characteristics you’re after, or, just not use it.
