@Black-Square i investigated a little bit more into the issue in SU5, because i thought maybe it fixed itself because of the new multitasking but unfortunately i still have the same issue. periodic micro stutters coming from the graphics queue.
but i found the following: if i increase the "Off Screen Terrain Pre-Caching" value it gets worse, and if i lower it, it disappears. so maybe this give you some hint in a direction?
again the problem is: periodic (like every second) microstutters in the TBM850 (and basically other blacksquare aircraft). the graphics queue goes from around 5ms to 15ms every second. which introduces microstutters. ALL other aircraft work fine. PMDG, fenix, taogs hangar, comanche, learjet. it only happens in the blacksquare fleet. sometimes it's worse, sometimes it's less, but the graphics queue is definitely behaving strange in all black square aircraft. it also happens when i have the display refresh rate at a lower setting.
