Flight Approaching Render Range of Landed Crafts from Orbit Causes an Accumulative Drop in FPS (85fps to 8fps in 2 minutes using time warp)

KSP2 Version: 0.1.1.0.21572
Operating System: Windows 10
CPU+GPU+RAM: i9 9900K+3070ti+32GB
Monitors: Using 2 Monitor Setup 1920x1080 for Both Using -popupwindow for KSP2
Mods Used: None

I say approaching render range because this happens well before I see the icons pops up in scene.

What is happening in Save:

• There is 1 craft in orbit.
• There are 6 crafts all in the same area on the surface of Minmus.
• Craft icons on the ground show up for a very short time on the ground when I pass over at approximately 50km.
• At 50km I can't see if the crafts are rendered or not (capture view mode). They could be under the ground but I can't find them.

Video Evidence:
Under timewarp (will see within 10 seconds the first drop in frame rate):

Without timewarp on first occurrence (97fps dropping to 52fps)

Additional information:

• Stuttering is when it's happening. Feels very similar to when a craft comes within render range in KSP1
• I am still testing to see if I can narrow this down to a more specific cause.

Additional Thoughts:

• With other testing when there are less available Kerbal slots within a craft the drop in FPS takes longer, or that seems to be a factor.
• i.e. It might be related to the available Kerbal slots that can be on the crafts (No Command Chairs were used)
• It might be related to the cockpits/crew cabins with gold windows that haven't had their internal parts added yet where the Kerbals aren't visible.

@Dakota I don't know if you or QA relook at bug reports that have been updated or not so I am tagging you.  I avoid tagging if I possibly can.
