Steps to Reproduce

I am in the process of optimizing my own map and was stunned by the bad frame time, despite an fps of over 40. I noticed that result even with just the landscape loaded, no other objects.
So I loaded a Fortnite template to double check:

1.Load and play the tattoine inspired Fortnite island template.
2.Open the spatial profiler and run the diagnostics.
3.Note that gpu time and frame time are way over limit.

Expected Result

I come from the artistic side and don’t have the technical knowledge to optimize my map in a creative way, instead rely on the tools the engine provides.
I would think that this very professional made map with a fairly simple landscape material and hardly any objects in sight would show a very good frame/gpu time at the location in the screenshot.

Observed Result

As you can see the spatial profiler shows gpu and frame time way over limit. Am I missing something, and what should I make of these results? Is this a malfunction in the profiler?

Bumping for visiblity as the profiling tools seem very wrong, e.g on an empty grid island it flags issues - this is not good, if developers get too used to ignoring these performance warnings becuase theyre wrong then actual issues may get missed, this literaly eliminates the point of ahving these profiling tools
