Update to my previous post.
Had stutters at low levels come out of the blue. Solution: Emptied Rolling Cache and set size from 8 to 20. No more stutters - silky smooth.
I have since run about 20 gate to gate flights in the A320 at most major US/Can airports. on about the 21st flight, I started to notice frame glitches and stutters appearing upon landing. Solution: I emptied the Rolling Cache again and increased size from 20 to 40. Restarted and silky again.
I’ve seen that this solution doesn’t work for everyone, but it’s been effective for me. Seems like there has been a change in the way the sim manages the Rolling Cache and once it’s full, it’s not recycling old files… ?
I’ll see if my number of flights increase before having to empty again.
