LOD settings investigation

Well those photos tell a story.  It shows the changes clearly.

As for the morphing of mountains and coastlines, even at high settings, I can still get that right next to me. 

I think it is just a game engine thing carried over from FSX / P3D, so it could be difficult to rectify.

Thanks for sharing. I can confirm for my machine (Ryzen 5600, RX6900) that a setting of 400 will drop my frames from 80-90 to the 30 area.

What I am curious about: there's always a mention of synchronous setitngs (say 200/200, 400/400 etc.) But a setting of 400/ 200 (Terrain/ Objects) would also work, right?

I've settled on 450 for both. Thanks for your detailed research and sharing it with the rest of us. I may back it down to 400.

That's interesting as I wasn't sure if smaller increments would work, using VR 200 is just about alright, 400 and I lose 5fps, 300 just slightly too high so I may try 250 later. Probably won't see much of a difference but every little helps.

Yes, they are totally independent.

Very interesting findings. Even at Terrain LOD 400 I can still see changes up close. I thought it was suppose to effect only the terrain mesh/textures out in the distance only while the closest to you should already have their mesh/textures fully loaded in and sharp already.

I am also curious to know if having higher LOD settings means that it will use more of your internet data/bandwidth? Especially for those who have a capped bandwidth limit every month. Like LOD 400 vs 200 will it double the amount of data needed to be streamed?

It can make a difference theoretically,  because with higher LOD you download more textures and stuff at both sides of the "corridor" represented by the route. But I don't think it will double with LOD, I can check and report (this must be checked with an emptied and disabled rolling cache of course).

However considering how massive are the updates alone, MSFS isn't really viable for capped data users...

So I tested with a LOD of 4.0000 and I get some stutters and it's not as smooth as 2.0000. I'm a bit surprised that my system can't handle a LOD of 4.0000.

Exactly. I am afraid this eludes any simple solution like a parameter change etc. as it's deeply hidden in the terrain engine. Thus I don't see a quick solution but hope Asobo will  keep it on the agenda and deal with it in the longer run.

Kind regards, Michael

Since the morphing of terrain mesh/textures is still evident inside MSFS, I really hope they will rectify the issue. It's one of those other immersion breakers. So far, they've accomplished a lot with the sim over 1 year. If they can fix that issue along with improving the coastlines, especially mountainous ones, that would be great.

Good info. Thanks for putting that together, Fuzzy. I like the overall feel of the sim at 200/200 (just seems less under load) but I have tried 400 and 350 and think the difference isn't really worth the extra load. I also assume new aircraft in the pipeline will further tax my system, so ultimately 200/200 might be needed when those arrive.

Thanks for the testing and info!

All of this was tested while the tree distance bug is active right? So when it's fixed (hopefully not months from now like last time), the terrain LOD should not have to be as high?

Right now I'm on Terrain LOD 4.0 and Object LOD 3.5, and the trees still are capped way too close.

Yes, hopefully they fix it again soon 🙂

Thank you all for the feedback!
