Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes

Same as OP, wait a few minutes, stutters and frame rates drop to unplayable state. Black screen avionics after taking off. Now getting game license cannot he authenticated. Reinstalled 5 times already.

Yes (Using Xbox Series X)

Performance degradation (significant) vs previous version of the 787. Unplayable at Asobo Handcrafted airports such as EGLL with both micro stutters and large ones.

Hello everyone, I’ve been testing and trying to find what’s causing this to happen and I think I found the reason (may be one of the reasons lol).
So after I selected my STAR and FAP the sim is where the heavy and continuous stuttering started (Stutter every 3 seconds), then I deleted my STAR and FAP and the stutters disappeared, I would say that it is related to the VNAV and other calculation that the sim need to load, if the STAR have a lot of constraints the stutters are heavier. Hope this help WT or asobo to fix this.

Set aircraft up cold and dark
Provide extra information to complete the original description of the issue:
Upon executing all of the information into the CDU, the sim freezes and ultimately causes a CTD—this could be because of airways within the flight plan or due to certain airports. I’ve done two flights with no airways with no CTD from KJFK-KORD and touch and goes at KPHX; once I attempted a flight that contains airways, the sim would crash with each attempt.

For anyone having issue in this thread, we will need you to provide the full flight plan that was attempted to be entered, as well as your performance data as you entered it.
same issue. Loading a STAR/Constraints in the FMC makes the sim to start stuttering. Everything went normal after deleting the constraints, as expected.
ZFW: 177.9
CI: 100
CG: 24.5
CRZ FL: FL380
Video showing how the sim stutters when I loaded the VUTEB3E STAR.
“OK, it may be related to the VNAV performance simulation. We run a whole integration/mini-sim of the full flight periodically (which is how the real systems work as well, but they aren’t also trying to power an entire real sim too)”
Asked by a user experiencing the same issue on Xbox Series X|S
Great - I also noticed generally poor performance on PC (747 at airport, mainthread limited, lower FPS than other aircraft when compared by swapping around with Aircraft Selector in dev mode)
Stutter seems to stem specifically from selecting a STAR via the arrival page and not the waypoints themselves. I unselected the STAR and entered the exact same waypoints and constraints manually, and there was no stutter.
Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes. Along with that, whenever I press execute button, sim freezes.

When using the flight planning screen, after putting in performance numbers and I need to press the execute button the sun freezes.

Something else that I realized is that if I load a STAR or add any constraints the stutters won’t start until I load my PERF INIT page, after loading that the stutter appeared.
I have to say overall performance/stable frames of this plane in particular did a nose dive after the most recent update, but it’s the stuttering that’s really bad and IMO a top priority issue to fix before it can go public.
Yep, I did. Only thing I noticed is that when I create a fpln that have more than 80 fixes the stutters appear once again, the stutters due to loading procedurs are gone
