Brief description of the issue:
Before opening MSFS2020 my bandwidth is about 150Mbps (Wifi and by cable). After opening the game, as soon as the menu appears, it starts acting like a limiter. My bandwidth drops under 10Mbps. Iāve also emptied the community folder. I donāt know what to do. Iāve done multiple speed test by different providers.
Provide Screenshot(s)/video(s) of the issue encountered:
Detailed steps to reproduce the issue encountered:
Do you have any QoS services running on your PC or in your router itself? I donāt believe this would be MSFS doing this but rather your network reacting to the data consumption / throughput of MSFS.
I agree. Applications that donāt have admin or kernel-level privileges probably cannot directly limit the bandwidth of other applications running on the same Windows system.
Not that Iām aware of. I havenāt changed a thing on my laptop. Iāve only installed a VPN client for my work, but that is inactive when Iām starting MSFS2020.
I did the Google speedtest, the one from speedtest.net and also the one from my internet provider Ziggo. The Google speedtest gave some strange figures, so I donāt think that one is very reliable.
Aside of testing the bandwidth on my laptop, I also did the tests on my mobile phone at the same time. The bandwidth on my mobile phone didnāt change.
Well I believe that the VPN is only used to connect with my workstation at work. And that all other internet services runs through the normal route. But Iām not that familiar with VPN and internet connections and how all those things work. So I could be wrong.
This is a possibility. You can find free trial vpnās on the net and try one of those. Just be careful though if you dont know what your doing you could hose your work vpn. If you have an āin houseā computer person at work, ask them if its safe to use another vpn for what your trying to achieve, or ask them if the current one will work.
Are you sure its a vpn connection and not a vnc connection to your work computer?
Sorry, I havenāt got time past couple of days. I just did another test with my mobile phone as a hotspot for my laptop. This was with a 4G connection, so that I could exclude my internet provider at home. And the same thing happened. As soon the simulator home screen opened, it acted like a limiter. The bandwidth dropped again. The speedtests all shows the same image as with the regular internet connection. The bandwidth peaks at the first second and after that it drops immediately.
Patch: 1.26.5.0
No files in the community folder
No bandwidth limit set in the settings
This is not the first time Iāve seen complaints that the game is somehow limiting total bandwidth far below their normal bandwidth. Iāve tested this myself a few times and havenāt been affected. However the game download is never anywhere near my total download speed. It usually tops out around 150-200mbit on my 1gbit connection, but Iāve been able to do speed tests and get a result that is about my total download speed minus what the game update is using.
There must be some configuration difference or driver/hardware issue that is triggering this bandwidth limitation by the game download.
I certainly feel the download process could be better streamlined. It downloads a lot of small files and is opening new connections for each one instead of using the HTTP/2 feature of keeping a connection alive and requesting multiple files which would keep the download speed high instead of having to start slow and ramp up the speed for each file. Iāve also noticed the game opens a lot of connections at the same time, and some drivers/hardware donāt deal well with many simultaneous connections.
Get a copy of ping plotter, now start msfs and get a flight running, now go into task manager, click on the performance tab, then at the bottom click on resources. Now find MSFS in the list of running process, click on it, this will show just msfs related processes. Click on the net interface either eth or wlan, now you see where msfs connections are. Write down the ipās in the list.
Now you can close MSFS and taskman now, open up pingplotter, and enter one of the pings on the list that you got from when MSFS was running. You should now see how traffic is running along that route, things you should be looking for is either packet loss and or latency. If there are systems along that route that return no info thats to be expected and nothing to worry about. Now if your seeing Packet Loss or latency along the route make note of them.
Now all you have to do is figure out whether those sites are related to your providers network, or if the connection is being stepped on by something on the outside your providers network. If its inside the your providers network, take screen shots (repeated times of day are best) and then provide them with this information. Its was a real PIA to get my provider to admit the problem was them, but eventually they did, of course going on a year they still havent fixed it (high latency issue), but now it seems everytime I fuss I get another 120mbps added to my account, still doesnt fix the latency issue, but Im upto 330mpbs for the price of 100mbpsā¦ ;p
a note: MSFS is realy nothing for what your Mobile-Provider offer the āmobile connectionāā¦ this kind of connection works in a completly different way than wired ( how the packages priorized, etc. ).
And here my test:
Without MSFS running:
MSFS in Main-Menu:
reval on different test side:
=> Result:
There is absolutely no Limitation caused from MSFS
I use a Wired Ethernet Connection and there is a long way: switch ā swtich ā powerline ā powerline ā router.
So,ā¦ may be you have to seach the issue on your System, Network,ā¦
The same thing happens as when Iām using the wired connection from my home network. So itās not caused by my home network, but something on the laptop.
But I discovered something new, it is also happening when I start Cities Skylines. So Iām not sure what it is. So my laptop is going is some kind of different modus I think, but I donāt know what that could be.
Could it be these updates? Those are the only things that I could think of.
I found the problem. Apparently Lenovo Vantage (some kind of control center which came with the laptop) has a network boost option, which was activated every time I started a game. It was suppose to limit the bandwidth to any other services than the game. But instead of doing that, it also limited the bandwidth of the game. The strange thing is that I never changed a setting of the network boost, maybe something happened after an update. But I feel a bit stupid that I never checked it.
But thanks to everyone who tried to help!
