I saw a thread someone posted about this before the software was released. As usual, it turned into something of a pissing war.

However, here's my observation and I'm asking you guys if y'all notice the same thing and if this is how flight simulator is programmed. I'm genuinely curious....this isn't an observation post about wether or not I like the sim. This is a post because if this ain't normal, I need help. If it is, I'm going on my merry way so I can continue flying.

I was flying a flight in the tbm 930 from Palo Alto to San Diego. When I got to around 8000 to 9000 feet, I noticed my photogrammetry scenery starting dropping in detail and it looked like it was melting. As I got higher and higher, I noticed the satellite imagery started getting blurry as if the LOD radius shrunk terribly. Up at cruise , I noticed the scenery directly below me, behind me and in front of me was all blurry. When I started descending, the lower I got the scenery returned to normal.

Is this normal behavior? Thanks!

Running 4k...

8700k OCed to 5.0

Rtx 2080ti

32GB of g skill rip jaws V 3200mhz DDR4 Ram

It's on an SSD

According to ookla, 240ish Mbps

FS was showing a long of 30ish ms at the time.

Hi, I had the same issue. check your graphic settings. There should be a setting “terrain level detail” or something, set it to 200. That solved the problem for me. 

Ehh...dratz. I have that all the way up to 200 as well as the other slider to 200.

I'm thinking about wiping my computer clean and starting from scratch with w10. Not because of this issue, just because i need to do some spring cleaning.

well considering in real life, the higher you go the less details you can see, so it sees they are modeling like real life

You should really post some screenshots for that. No one can tell if this is normal behaviour because we can't compare it to what we see in our own sim at the same altitude.

Here's what it looks for me at 10-20.000 feet (don't remember the exact altitude)

The Terrain Level of Detail slider has a range between 10 and 200.  The larger then number, the further out from the plane, the simulation starts loading higher resolution textures and mesh complexity.  

This is very CPU intensive, so if you have a lower CPU you are going to notice fairly frequent pauses in flight as the CPU has to crunch the new scenery data before sending it to the GPU for rendering.
 

 

I have a strange issue at high alt. It seems that instead of making the scenery more clear the more i get close to it, it making it blurry.

Your wisdom is great. I completely forgot about a screenshot. Thanks for the reminder. I should have one up around lunch time.

The sim originally preset my settings to ultra... I was like....nah bruh lol

Here's a recent screenshot from 30.000 ft.

Yours looks kind of like mine. I'm flying with my friend online right now around Hawaii lol. I'll post my pics later haha

The problem isn't your LOD radius is shrinking, it's that your visual range is increasing.  As you go higher up, you can see further out, so it appears your LOD radius is shrinking, when in reality, you're just seeing farther and farther away.

Aahhh hhhmmm...I see I see. That makes perfect sense. Oh well. You seem like a smart person...I put my specs in the OP. do you think any of those are a bottleneck for the issue at hand? I assume not considering the fact that it's coded in the sim?

Of course 4k is going to use 4 times the VRAM as 1080p.

So I'd say if there is a bottleneck in your system it's your Video card.  The RTX2080 Ti has 11GB of VRAM, but that's not even 3 times more than a standard 4 Gig card, and this sim EASILY easts up 4GB in 1080p.  

To run 4k at the same efficiency that a 4GB 1080P card can run, you'd need 16GB VRAM.

You don't have that, so some of that is being offloaded to your DDR4 ram which is slower.

You can actually kind of track the bottlenecks by turning on Developer Options in the General/Developers option section.  Then a small black menu appears, and there's a "tools" section with "View FPS".  You can actually see what's limiting, GPU or CPU.  

The UI has a max LOD radius of 200 (Whatever that means).  Some simmers have modified their config document to force the sim out to 900.  But if you thought LOD of 200 ate up CPU and memory, imagine what 900 would do.

Area of a circle, Pi R squared and all that jazz.

Smart guy you are. 

 

I've saved for the 3090 so hopefully all the VRAM will help.

900? Daggom! I have used that frame counter and it looks like it's limited by GPU mostly.

Sometimes it's limited by the mainthread but not as much as GPU. 

Thanks for all the insight and education. Really appreciate it!

Those are all wide angle shots.  If you zoom in a bit you'll see the blurry textures.  Especially if you fly over a runway ...they are the worst.
