Yeah in something like 1/3 of all sessions I get these big CPU spikes causing a big stutter once every 20-60 seconds or so. It’s not hardware related, it’s not even really a performance problem. It’s a glitch in the sim that (luckily) only manifests in 1/3 or so of my flights. It’s not related to plane, scenery, Server, or settings, apart from terrain LOD. Turning terrain LOD way down reduces the severity the more you turn it down, which is not a viable solution.
This seems to have started with SU14, I’ve seen a lot of people report it. In the other 2/3 of sessions, the sim runs near perfectly. Smooth and no stutters, very fluid.
Do you also find that it only happens on certain days, not all the time?
Also see my thread here that I just started and feel free to contribute:
