Fps drops when walking over moon fragments

This is a very minor thing, but its easy to see and reproduce (at least for me).

I was doing normal monolith that leads to lagon. The second story part “island battlefield”. You are supposed to collect the moon fragments across the map.

Then I noticed odd fps drops. Like from maximum to 10fps or below randomly. Then I realized it happened each time I walked to a moon fragment to collect it.

Then I tried not collect it, but just walk onto it. When I do this fps drops momentarily each time.

My pc is somewhat old. Not sure, if newer pc will have noticeable drop. Its just that this has not happened before and may happen elsewhere too and I have just yet to notice it.

Same issue here except worse, whenever I got close to the moon fragments my fps would plummet to about a frame a second. My PC is far from old; I have an intel i5-8600K CPU, NVidia 3060 Graphics card and 16gb ram.

Happened on all 6 of the fragments on the level where I got close and the game would just freeze and continue to be slow until I managed to pick it up.
