Performance Issues with Starship – Sporadic FPS Drops
-
Very interesting! That's admitted a little strange, since ND 2 runs the exact same code... This might take a little more experimentation. I will look through things later and see what I can come up with, but on your next flight, try configuring ND 2 to show exactly the same as what ND 1 is showing, and see if the problem is exhibited by both units. Thank you for the help!
@Black-Square Okay, I'm uploading another video showing the FPS drop. As you can see, only disabling ND No. 1 helped. Turning it back on doesn’t cause the drop either. But if we look at all three videos I uploaded, they’re all from the same route, and the issue generally always occurs around the same point — just before reaching the ROGAL point. Maybe it’s a coincidence, maybe not.

Thanks for showing exactly what I have been asking to see! I finally have a chance to spend some time on this later tonight. I will let you know what I find. At least you can continue your flight to landing after pulling one circuit breaker. I know that's far from ideal, but I'm glad there is some solution that at least gives you the satisfaction of a smooth landing while I work on the problem.
Did you try the BIOS change suggested above? Specifically enabling C-State Control? It would be interesting to see if that could change the outcome, now that we've collected some data.

@Black-Square Yes, I enabled C-State Control, but it's still the same. At least I can continue the flight by turning the circuit breaker off and on
. Thanks for looking into the issue.edit: I discovered something new — even if I turn off ND No. 1 and turn it back on, the FPS starts dropping again after a few dozen seconds. So I have to turn off the breaker again, but once I turn it back on, the FPS drops again after several dozen seconds. Unfortunately, I don’t have a recording of it because something went wrong and it didn’t record.
I also discovered that the FPS starts dropping for the first time between 55 -60 minutes of flight.

I have no idea if this is related as I have a 5800x 3d without C State but on tonight's flight on landing, the fps dropped to 10fps and this has never happened before. It could just be the sim, the servers etc but thought I would add here as it was in the Starship.

@toby23 If it was maybe 10-20ft off the ground and recovered shortly thereafter on MSFS 2024, this happens to me constantly with every single aircraft. I thought we were done with severe stuttering in the flare with FSX, but I guess not.

Yes, this was exactly what happened.
The ground textures turned very blurry in a small circle around my aircraft too, maybe a 10m radius.
The only add-on I use that changes LOD is AutoFPS but I use AutoFPS on every flight and have never seen this behaviour before.
Always a giant leap forwards and then fall backwards with this sim. I can't wait until it's more stable.
Thank you for your feedback and good luck with your Simisms
