steam link or moonlight？Frame drop in some complex game scenarios

[banyam]

In some complex game scenarios, steam link still has some fps drops even if the network conditions are excellent. But under the same conditions, moonlight can always maintain the same FPS as the host PC.

I prefer STEAM LINK because of its powerful touch controller function. This is something that moonlight cannot do, but moonlight is very smooth and stable.

Why can't steam achieve the same excellent streaming performance as moonlight? Valve has a stronger and more professional development team.

steam uses alot of network traffic for remote play
~30-50mb/s for 1080p60

you can also try enabling/disabling hardware encoding/decoding on host and client
ymmv

I think this is not the problem of network, I streamed at a local area network and network testing at 105 mb is excellent.

I streamed though a NVIDIA 4090 card, most games can keep 120 FPS in steam link. But in some complex game scenarios, such as scenes with lots of vegetation and lots of traffic, it produced frame drops (120 FPS to about 80 FPS, when you adapt to 120 FPS, suddenly dropping to 80 FPS is noticeable), but moonlight did not.

So, can steam optimize streaming performance like moonlight?

[_I_]

steam grabs complete frames, using vsync
if the display on host and client are 120hz, it will capture at 120 or 60

just make sure nvfbc is enabled on steam streaming settings on host

check steam\logs\streaming_log.txt
see if capture framerate is dropping, or any errors

OK, I'll take a look into it, thanks!
