Frequent lagging and frame dropping #137

Basic information

Description

Hello, I hope I'm posting at the right place ! I have Moonlight installed on my LG OLED65C1 TV, which is connected to the router via Ethernet, same with my computer. Despite the computer running the games smoothly no matter the resolution (same in 720p, 1080p or 1440p), the stream on the TV is constantly lagging like 2 times every second. My internet connection is about 400Mbps, so I don't really understand where they could come from.

I've tried different video encoders but it doesn't change anything.

Thank you in advance for any help, do not hesitate to tell me how I can provide any logs if necessary.

Hello. Are you connecting with Ethernet or Wi-Fi?

Choumpsi commented 2 years ago

The TV is connected to the router via Ethernet, and the computer is connected via Ethernet as well.

mariotaku commented 2 years ago

It sounds strange, but did you try to connect your PC to router via wi-fi instead?

mariotaku commented 2 years ago

Some reports severe packet drop while on Ethernet. You can confirm by open performance stats with long pressing back button.

Choumpsi commented 2 years ago

Yes, I tried both combinations.

For this example I have Moonlight settings on :

In case it may help, my computer is running the game on 1080p with :

Having the PC connected via wi-fi I have :

Connecting via Ethernet, only RTT drops to 2-3ms. The rest stays the same. In both cases, the decode time is about 0.3ms. The app constantly says "Unstable connection", maybe it is a TV-side problem I don't know.

Thanks for your help.

Try forcing the host's ethernet adapter to 100Mbps. It's annoying, but it fixed the problem for me.

I had the same issue. Doing as Bruffandino said fixed it for me as well.

Same problem here, but my TV is a LG OLED55C1. Tested different resolutions, codecs, ethernet adapter speeds. Nothing fixed it.

GaspardMonier commented 2 years ago

Same poblem, I also have an OLED55C1 connected to wifi 6 My PC is connected via ethernet

Same problem for me. OLED48C1 wifi ac --> router <-- PC rj45 GbE (250 mb/s)

rtx 3070 ti ryzen 5800x 32gb ram

Works well over wifi.

Edit:

Finally, after setting the wifi channel to auto the problem went away.

Any update on this issue?

I hadn't used moonlight in a while but fired up the WebOS TV app tonight to have a go and ran into what I think is this problem, really laggy video that completely freezes up and displays 'Unstable video' in the top right corner. Updated to the latest moonlight version, PC video card drivers etc, and messed about with changing client decoder types and quality settings - but couldn't get anything to work until I found the note here about Host link speed.

Switched Speed & Duplex in my ethernet adapter settings from 'Auto Negotiation' (which always picks 1gbps) to '100 Mbps Full Duplex' - all of a sudden streams flawlessly like it used to.

Setup is Windows PC -> WebOS client on an LG C1, both wired to MikroTik hAP ac3 router via ethernet.

Obviously this workaround works for some folk, but seems real strange and unideal switching adapter speeds every time :)

What about a USB NIC? Not so ideal either but that's an issue that can't be solved on the app side...

Ah so are you suggesting this like a known limitation? Something changed in the way NVIDIA gamestream is working on the host or something? Just confused because I've used for hours on the same hardware and now it's suddenly gone weird. I have noticed the C1 had a software update recently though as well

bluefantail commented 2 years ago

Just spotted it does indeed appear to be a suggested workaround in the moonlight troubleshooting docs https://github.com/moonlight-stream/moonlight-docs/wiki/Troubleshooting#video-is-choppy-or-laggy

Try forcing your PC's Ethernet adapter to run at 100Mb Full Duplex in Device Manager.

Missed this initially!

According to some reports, LG TV have 100mb NIC and when you connect it to 1gbps NIC it will have bad performance. I'm not quite sure because I'm connecting with a 1gbps switch right now...

Yeah the LG C1 only has 100 Mpbs (I think pretty standard for most or all LG TV's). I don't know enough about networking to understand why the host having a different rate would matter though
