I did a video with the downloadable exactly flight plan, for benchmarking purposes, explained and showed that you can replicate almost exactly practically a benchmark flying with the IA from the beginning.
With LODs 200 I have real stutters and around 50~60 with the same conditions and stock A320, the half. I think I do not have a problem, watching how it performs at LODs 100 in my video, though who knows. Yes improvements in the future there will be, though miracles I think that no, though maybe.
