Internet connection speed - minimum practical neccesary?

Featured Replies

A friend who runs a P3D installation for a volunteer real world pilot association wants to install and use MSFS.  They have the computer power but I test their internet connection at less than 15Mb/sec.  My connection is >300 Mb/sec so I have no idea what MSFS is like with a slow connection.  The physical location of their training facility prevents any upgrade to the internet connection. 

They use the sim for pilot training for specific low speed / low level VFR missions. Quality of the outside view is the most important consideration.

1) In general use - who can tell me the PRACTICAL impact of less than 15 Mb/sec?  Who is actually using MSFS on a regular basis with slow internet?

2) Will a big enough cache eventually diminish the negative impact of the 15Mbs/sec if they stay within 10 or so miles of a given target?

I have been using MSFS with 7 Mbps which is fine, as long as I disable photogrammetry.

Downloading an update is a pain though.. 😉

In my experience stability is more important than the total speed. When you use WiFi but live in an apartment building with lots of interfering WiFi networks, connection may be interrupted for just a few seconds, or speed drop to nearly 0, and the sim will go to offline mode or switch off streaming data because of that. This can happen even though your speed could actually really high.

I now use a LAN cable to have a stable connection. If you don't want to have the LAN cable plugged in all the time, you can also use it to download data for the offline cache.

The very bottom line is about 2 Mbps as Bert says; without Photogrammetry. This was my speed when all I had was a lousy mobile data connection from August last year until about 3 weeks ago. It works, it's jerky but it works.

i have 6,5 and it work ok,Photogrammetry on and set high to ultra......loading takes a litle bit longer.....

I started with  a 4MB per sec wi-fi connection, no photogrammetry. It worked pretty well.. pretty close to how it runs with my now 12MB/sec. I don't care a bit about the often weird looking photog
