So it looks like MSFS 2024 has a new LOD feature for cabins that helps to improve the FPS. From what I understand, MSFS 2024 can show detailed cabins without sacrificing the FPS as much because it uses some new LOD feature for cabins.  IniBuilds is using this LOD cabin feature in MSFS 2024 and FSElite briefly talks about it in their preview of the iniBuilds A350:

Speaking of cabins, we got a full tour of the A350 cabin. It will only be available for Microsoft Flight Simulator 2024 (due to how the LODs are modelled and taken into account for performance), but it is impressively detailed.

Because iniBuilds is trying to ensure iniBuilds A350 runs well on MSFS 2020 as well, it looks like the cabin for their MSFS 2020 version won't be the full version of the cabin compared to the version for MSFS 2024, to preserve the performance for MSFS 2020.  MSFSaddons talks about this here:

Full interior model: Available only in MSFS 2024 (iniBuilds Store & Marketplace PC/Xbox). The MSFS 2020 version will have a simplified interior model without cabin or crew rest areas

I would be interested to see if other developers will also make use of this MSFS 2024 cabin LOD feature.

PMDG are you listening? I want a cabin for my 737 not to look around but the wing views are the best. With the 777 I use the passenger view a lot. Finally get to see the scenery in a jet. Obviously the wing view has no immersion of I pan round and there is no cabin just nothing. 

If they used depth of field correctly in the cabin you could get away with bluriness and low textures on all seat rows but yours, would really help performance. 

The 2024 version also has a cabin "less" option because if the streams were any evidence there are still a lot of questions to be answered about performance...  They even commented about it on their discord.  

It "should" perform as well as the Fenix 320 but because it may not across multiple systems they are also offering a version for 2024 without the cabin as well as low resolution textures for 2024.  

It's interesting something that is designed to improve performance in 2024 may have to be disabled or run with low resolution textures if it is too much of a performance hit.  🤷‍♂️

Thanks to @Tuskin38 for his screenshots of some of the iniBuilds developers in their Discord channel explaining the new LOD system for cabins:

Well pmdg might need a improve the textures but their performance is awesome and beat any inibuilds or Fenix aircrafts at least on cpu. I hope they keep like this even they get better textures which only should affect the GPU and vram

Yup, the PMDG 737 has really good performance in MSFS 2020.  That's surprising, since the PMDG 737 is such a high fidelity aircraft.  I can live with the poor cabin in MSFS 2020.  However, if PMDG can utilize this new LOD feature in MSFS 2024, if they ever have a paid version to upgrade to the latest MSFS 2024 features, I hope they will take advantage of this new LOD feature in MSFS 2024, to make a better cabin for the PMDG 737. I wouldn't mind paying up to $10 USD for an upgraded PMDG 737 in MSFS 2024, as long as it has a much better cabin, but the FPS is still very good in MSFS 2024 even with the new cabin.

I thought the 737 in 2020 didn't even have a cabin? I'd have used it for wing views if I'd known, it's one of my favorite planes.

Yes it does, you just can't open the cockpit door but there is a full cabin back there...

When I purchase a flight simulator, it's for the purpose of building/maintaining my skills a a pilot, not as a passenger. So far as I'm concerned, no cabin is required and I would be especially unhappy if I had to upgrade my system at great expense because of the computational burden associated with that feature. I'm perfectly OK with an LITE option, of course, but I don't want to be forced to upgrade my rig just to sit in a passenger seat and look out the window. I can buy a ticket IRL if I want that experience.

Fortunately for you the 2020 version has no cabin and due to the modular nature of the modelling in 2024 it can be flown with or without a cabin in 2024.

Thanks for confirming that point. It would be great if other vendors follow ini's lead in that regard.

It's not only the lod system but the modular system can changes things on runtime, the combination is a leap forward in 3d space 😉
