Add it to the list:

Massive stutters with DF client

i912900k RTX3080 DDR5@5200 Perfectly smooth fps prior to update, 170fps locked nearly everywhere outside of the most strenuous activities. Since the update has been out its near constant stuttering as assets “pop in”. This seems very similar to DX12 compiler issues that plague other games where first exposure to an art assets causes fps stutters.
