CU13 improves a number of cities found in Samscene’s USA Modern Cities packs. I’ve not had chance to check yet but I wonder if any are now broken as a result?
Not sure but that’s exactly why these updates are opt-in and not applied by default, even when conveniently streamed in 2024.
The onus is on Samscene. It’s just cyclical and therefore frustrating. They usually come good, though. Just takes a while.
Oh, fully - just addressing the question/complaint many users have when they have to go in and enable these updates. Not a constructive reply to your post though, apologies.
I intended this thread to be more of a place to collate findings, since Samscene do nosy around here.
I can confirm that L.A is still fine as well as San Francisco. I did not notice any issues at all.
Edit: However I did not check the SoFi Stadium north of KLAX.
San Fran was recently updated in the last USA WU so that’s not too surprising; good to know LA is fine, too. San Diego might well be broken as I don’t think we had PG/TIN there before this CU?
San Diego already had photogrammetry before.
For several months now, all Samscene Modern City Pack folders have contained a small tool that can be used to disable individual cities and even the SoFi Stadium near KLAX if compatibility issues arise. Of course, this probably won’t work in the Marketplace version.
I’ve just checked San Diego and it’s perfectly fine, no issues. It has always been PG/TIN although the PG/TIN coverage has not been extended, unlike San Francisco, Oakland & L.A has had quite a bit of new PG area added. Check out my topic Which are your "Top favourite Cities/Places" with the best Photogrammetry to fly in? fspghangar.com - #1060 by AirRhodesia for the new PG Coverage Maps I just did.
Incidentally, I experienced significant FPS drops when I had both Inibuilds KLAX and Samscene Los Angeles installed. After deactivating SoFi Stadium, performance improved significantly without me having to deactivate the rest of the Samscene scenery for LA.
I have gone into the configurator apps and intentionally disabled LA and San Francisco just to be safe. But I only own packs 1 and 2 and those are the only California cities in the two of them.
I wish they would put just a fraction of the time into the autogen scenery that they do in photogrammetry
You wish they would handcraft the autogen scenery? 
No, of course not, however, the autogen buildings could be much better than they currently are. They said new autogen was coming with 2024 but sadly it never did.
Tried to have a look at the Griffith Observatory and I am still getting just the PG version.
Happy with the upgrade. It is smoother flying above LA now. The trees are still bad though…
Shortly after that post, I recalled San Diego having PG.
Try deleting your rolling cache or emptying your scenery index folders (if the former doesn’t work). This should determine whether it’s a cache issue or an actual conflict.

I checked MSFS 2020 and see no issues with SS3D Volume/s. Not so with 2024, one must move the Volume/s down the scenery order list (Higher priority) to resolve issue/s. You stll might have subtle issue/s afterwards. Have made mention to SS3D that he may have to have a look.
