TBM900 sound & video stutters every 5-8 seconds

[oldsimmer]

running x-plane 11.55
just installed the TBM900.
am getting a video & sound stutter every 5 seconds, and its two quick stutters about a second apart then ok for 5-8 seconds then stutter repeats the cycle .
system is win10 pro, i5-9600KF, 32gb ram, Geforce RTX2060.
No other planes do this. CPU utilization was around 50-60%

sorry, no log file
Any ideas? as I would also like to purchase the Hot start challenger 650, but not if their products have stutters.

We need a log file.  That will tell us everything about your X-Plane install, and a possible cause for the stutters.

It could be anything from excessive use of plugins to scenery loading.
