Last night i was setting up my first flight using Fly The Line - Short Haul Edition, and everything was running perfect. I had my flight plan loaded but decided, since i am using the Fenix for this let me try GSX Pro one more time. For reference, I was using FB KDEN which i use all the time in MSFS 2024. I load up after installing GSX and when i pan i get stutters. Unflyable stutters.  I immediately unlink GSX but the stutters remain. Then i uninstall GSX. I still have stutters. I spend two hours changing graphics settings, clearing cache, uninstalling KDEN, uninstalling FTL, etc. So i load up KORD and no stutters. I go back to KDEN and stutters. I decide to disable Photogrammetry and no stutters. 

I will add Photogrammetry back today but this was very strange. I have no idea if GSX played a role in this, so maybe it was a coincidence? I installed it again and no problems. Seems like something got corrupted for Denver Photogrammetry, but i thought that was streamed. I don’t understand enough about GSX to know if maybe it corrupted something that would remain corrupted even after it was uninstalled? 

Then again, maybe it was a server issue. Idk.

I had the exact same issue last night at KDEN using the xcoderversion, was  not able to pinpoint the cause

Does it happen if you turn off Photogrammetry? 

I don't know if this definitively was the solution, but I went into the WASM folder and under the Fenix folder I deleted the .cache file. Stutters seem to be gone. 

Turning photogrammetry did not fix it for me. 

I have this exact same issue now. I just updated the x-codr scenery and it is a stutterfest at Denver now, it's completely unflyable.
Tried different planes, uninstall reinstall scenery. The problem only arises with the newest x-codr KDEN installed, maybe it needs an update.
Spent hours today troubleshooting it.

Me too, except I TO out of KBJC and with or without PG enabled very stuttery.  Once over the Front Range west it all smoothed back out.  And, I use Gaya Sim's KDEN which is perfectly decent.

Denver does use Vexcel PG (the super hi res stuff) so if you were loading that area it could be a factor.

But I disabled it and the stutters remained.  Maybe disabling does not fix this if the session started up with PG on, can try again starting w/ PG disabled.

1 Denver departure, Salt Lake City arrival. Inibuilds A320 I only flew the first few minutes. No stutters, no pauses. Not in cockpit view panning. Not in external view panning. I'm in the latest beta. I'm always sad when the glory days of the betas ends.

2 New flight with no departure, only arrival in KSLC chosen on the Msfs world map. No stutters while landing there.

Same for me yesterday, departure from EBBR to LFPO and lots of stutters.

What’s strange is if i start a flight at the xcodr Kden gates, no stutters and perfectly flyable. If I start outside the terminals such as the cargo ramp, severe stutters and fps drops. I have never had a problem with this until suddenly last week. I have made no changes and not in the su 5 beta

It must be server related.

I think if you wee in the su 5 beta things would be way better for you. They are for me. I went in and out of the beta, back in forth. The beta version is way more stable and stutter free. 

I had stutters this evening, quite severe at times but it didn't last for too long. Flying over Mexico/USA VFR, not near any airports to warrant a sudden influx of aircraft (using FSLTL) so more than likely MS Azure server related.
