On a flight through Canada to PAJN I experimented with changing tile severs and LOD and ending up using the ArcGIS tile sever (Google Tile Server Mod).

Then I figured out that the FPS difference between LOD 200 and 100 was 1 FPS because FPS is related to generating screens while LOD is related to loading data.  Not the same thing at all.

So the assumption is that if your FPS is bad at a high LOD then maybe you need better connection bandwidth.

I beg to differ if i understand your post correctly. At altitude above 1500ft, i can run lod 200 at 4k ultra at 50fps limited externally - GPU and mainthread running green in dev mode, just done this tonight in the 737 , I only have 34mps download broadband.

Even at 400lod at altitude i get 40+fps GPU limited, beautiful and my internet does not get hammered as viewed in resource manager.

On the ground upto around 1500ft i need to run lod 150 to maintain 35fps, mainthread limited.

400 lod on the gound - 15fps - both mainthread and GPU exceeded. Download still not maxing out.

Open the dev mode and monitor main thread when adjusting lod on the ground and you will see the impact it has on the cpu mainthread, that cuts your frames.

Once airbourne the lod has less impact on the mainthread and your frames will be less impacted by the lod adjustment until you max out the gpu. Here you will see little change in fps when adjusting the lod until you reach a setting that maxes out your GPU.

5800x3d CPU

RX6800 non XT variant GPU

I have dialed LOD back from 300 to 200 and I have all my frames back at 40+.  The second LOD goes above 300 my frames drop to 25-30 on the ground.  Very wierd because i used to run 300-400 at 45-60 FPS on the ground not sure what is off.  Hopefully, this gets solved or someone finds a fix.

Completely wrong. 
LOD hammers your CPU. If you run dev mode on ground you can clearly see what LOD does to your CPU. 
 

High altitude doesn’t matter cause you’re typically not CPU limited. 
 

Run your tests on ground again 🙂

This is so wrong in so many levels...I must be doing something wrong then.

fly safe
