Thanks Jack.

Much cleaner than the two I am posting below. You can see 'rocks artifacts' under & in front of & behind the aircraft. This was at 144 Mbps. I will try & see what I can get if I can get the Mbps up to 866 by shutting down then re-firing up the Modem. The Modem runs hot & the speed I get varies all over the place, but is mostly at 144 Mbps, which is not the best for flying.

What’s the latency to the MS server you’re connected to?  Wireless connection will tend to introduce more latency and is less stable than hardwire connection.

For Photogrammetry to show correctly (no melted buildings) you need 125Mpbs at a minimum sustained (assuming you have max OLOD/TLOD) and latency < 15ms (<10ms is preferred).

There are other issues that can trigger melted buildings, but in most cases your latency and sustained data transfer speed will be the determining factor.

Its a wireless connection to the Modem.

How do you find the Latency?

My TLOD & OLOD are set at 100.

Thanks

Suggest you try hardwire connection RJ45 Cat6e cable or better … just route it for testing even if it’s not practical for your environment.  If you see better performance/consistency … then get a cable guy to install a couple of Cat6e or better drops in your home (really not that expensive $100 a drop).

To determine latency you’ll need to use Windows 11 built-in Resource Monitor tool and you should be able to trace it back to a related MSFS 2024 executable/process with an IP address or URL (I redacted my info but see sample below).

Take not of the IP address or URL, and then open CMD windows (run as admin).  Enter “tracert “ along with the IP or URL and that will show you latency and number of hops to the PG server.

I’m not at home right now, so this is just a sample of the process.

Very interesting. It would seem it might be server?

Might be the Xfinity modem. I'll see what SayAgain thinks.

Well, you seem to know your stuff🙂

So - I run Win 10 Home Edition

Core i7-10700F @ 2.90 GHZ

Nvidia GEForce GTX 1060 6GB GPU

RAM: 64 GB DDR4

Mobo: Micro-Star Intntl MAG B460 Tomahawk.

small TV Screen, 1920 x 100, 60 fps

Most of my settings are Medium. I would like to run Med/High. FPS is currently  locked at 30. I am aiming for smooth flying & minimal waterfall cliff faces, scarecrow trees & rock artifact buildings, all of which I can get when flying low.

Modem is an Xfinity XB3-T that currently  has a top of external case temperature of 91F in a room that is 60F. In summer I am sure it is running hotter. I am thinking of taking it to Xfinity to swap it out for something more recent as it could be about 5 years old.

It is wired to coax from the wall & is 10' from the flight PC so I could rig an RJ45 connection.

The Xfinity subscription states max D/Load would be 866 Mbps, but I rarely see that. 144 Mbps is the norm. Do they control that?

I did a speed test & got 13ms Ping, 435 Mbps download & 39 Mbps upload. I am trying to figure out if the Modem is faulty, or not.

Also, I am trying to figure out whether my PC spec is capable of doing Med/High Graphics settings.

Any thoughts?

Thank you

Your melted buildings are like due to your GPU Nvidia 1060.

Thats a really old modem, but should have 4 1G ports for RJ45. … test hardwire PC to Modem before you buy a new GPU.

But like I said above, you only need 125Mbps for PG.

Agree with this, given you've tested throughput at 435 Mbps download, that's unlikely to be the limiting factor.  I had a old powerline connection last year at barely 100Mbps which was enough.  Most likely the GPU I'm afraid 😞

I think the whole PC is a limiting factor🙂

Once I got into PCPartspicker & threw in my Mobo I found that it is limited to DDR4 RAM, which in turn limits the GPU choices to 6 units with 2MB RAM! Not the 16 MB I hoped for. Anyway, will test an RJ 45 cable.

Back to the question of why the Download can vary from 144 Mbps to 866 Mbps  - is that throttling by Xfinity?

Is there any way I can get it to hold steady at say 400 Mbps or more? 

Thanks

Its possibly related to broadband contention ratio?  If so, little you can do about it other than change to a different provider.  Although, I've found connection to MS servers have sometimes been problematic from my geographical location, and using a VPN to pretend to be in a different part of the world suddenly made a massive difference.  Go figure!

A broadband contention ratio represents the number of users sharing the same data capacity or bandwidth from an ISP, directly affecting connection speeds. A lower ratio (e.g., 20:1) offers higher, more consistent speeds, while a high ratio (e.g., 50:1 or 100:1) often causes significant slowdowns, especially during peak usage hours. 

Key Aspects of Broadband Contention Ratio

• Typical Ratios:
  • Residential: Often around 50:1 (50 users sharing 1 line).
  • Business: Usually lower, such as 20:1, for better performance.
  • Leased Lines: Often have a 1:1 ratio, providing dedicated bandwidth.
• Peak Times: High contention causes the most noticeable slowdowns during high-usage hours (e.g., 9 am–11 am or evening, depending on if it is business or residential).
• Cost vs. Quality: Highly contended services are cheaper but offer lower, variable speeds, whereas low or 1:1 contention offers high, consistent performance at a higher price. 

• Definition: The number of premises/users sharing the same internet line or bandwidth.
• Impact on Speed: When many users are online simultaneously (high contention), bandwidth is shared, reducing individual speeds and potentially causing congestion, similar to traffic on a road
  .

Contention Ratio Examples

• 50:1: 50 users share the same bandwidth. If everyone is online, your speed could drop to a small fraction of the advertised maximum.
• 1:1 (Uncontended): You have exclusive access to the bandwidth, ensuring consistent speeds, common with leased lines

Kevin

Contention Ratios: Residential: Often around 50:1 (50 users sharing 1 line).  Is that 50 users in 1 geographical location?. ie, around where I live there are a lot of teenagers within a radius of say 10 miles, could probably hit 50 users at night without difficulty. & there is a High School 5 miles up the road which probably has a heavy PC presence.

Anyway, for what I am paying Xfinity a month I am going to request a Gateway swap  out to something more recent, such as an XB7 or XB8, & see what that does.

Thank you for your insights.

Definitely go that route, but I think the primary issue is the nVidia 1060 GPU.

Were you able to determine MSFS servers URL/IP and do a tracert?

Haven't quite figured that out yet.

I did a test off this Laptop & got for row #5: 22 ms, 13, 13 and for row#8: 16, 14, 13 but I need to find the MSFS servers URL/IP & run it off the Flight Sim PC.

What do the 3 columns of figures represent?
