Editor FPS drops drastically just by clicking on certain devices

Summary

I felt the engine was getting abit sluggish so i enabled FPS through the editor settings and just went about creating my game and monitoring the FPS.

What i found is that when you click on things in the outliner the FPS can drop like crazy. I normally do something with the thing while selected in the Outliner then will not esc or unclick until later so when im moving about FPS is slow

What Type of Bug are you experiencing?

Stability

Steps to Reproduce

Just place a bunch of devices in the world and click them i guess

Audio mixer is a stable 120
Island settings is about 77
Input trigger about 68
Hud Controller is 33!!!

Expected Result

I would think it’d all be the same and clicking on something shouldn’t change FPS

Observed Result

It seems broken to me

Platform(s)

pc

Additional Notes

I will share a video but also not that when this is happening the GPU fans go into HV Mode causing strain on the GPU for no reason i can think of. This seems very wrong and does make the editor feel sluggish when moving about when selected on a problem device.
