Describe the Bug

I'm using sunshine and moonlight to stream games on a Windows 10 22H2 system. I noticed that when the system is idle on the desktop without any operation, the frame rate drops to less than 10 frames per second.
However, on Ubuntu under the same circumstances, it can even run at a full 240Hz frame rate.

I wonder if this is caused by the characteristics of the Windows DX API. Will upgrading to win11 help, Or which version of sunshine should I use?

Operating System Version

Windows10 22H2

Architecture

amd64/x86_64

Sunshine commit or version

024bd8f

GPU Model

RTX 4090

I have updated the commit version.

After upgrading to win11 24H2 and using WGC (manually starting sunshine), there are still only 9 frames in idle time

[ReenigneArcher]

I'd suggest trying the latest pre-release. There have been many commits since the one you linked.

[ReenigneArcher]

There's also a config option to min_fps_factor, you can set that from 1-3. 3 will result in a higher FPS when content is idle/mostly static.

Even when I try to set minimum_frame_time to 1MS, it won't go up to 64fps

[LibertyGM]

@ReenigneArcher , Excuse me, can you tell me, when will Sunshine be released? A lot of time has passed since the last release. Can you tell me when a stable release is planned?

[mrotame]

I'm having the same problem. I'm using the latest pre-release version v2024.1218.135629, and no matter the value I use in minimum_frame_time, the FPS doesn't change.

Having both a PC monitor and a smartphone with 120 FPS, games locked with 60 FPS are unplayable due to constant stuttering every ~1.5 seconds

The workaround I found for my problem, is to keep any small video/animation rendered in 120+ FPS running in the corner of the screen to force the stream back to 120 FPS

minimum_frame_time is only effective if the frame drops after the screen is still.
What FPS can you reach when playing games?

[momala454]

i confirm min_fps_factor is not working. I've set to 3, and it drops from 120fps to 20fps when idle.
If I then move the mouse very fast, i see a big compression artifact and the mouse stutter during a short time
i'm using the latest pre release

[mrotame]

minimum_frame_time is only effective if the frame drops after the screen is still. What FPS can you reach when playing games?

Normally the stream reaches constant 120 frames if something is being rendered with 120 FPS or more.
The stream usually starts with 120 frames, when it is still initializing, then it drops to ~60 or less (depending of what is being rendered in the screen)

If not set, it will drop to 9fps

Yes, me too. The mouse movement is slow when the connection is just established.

[mrotame]

If not set, it will drop to 9fps

In my case, no matter the value I use (1, 2, or 3) it drops to 9 FPS when idle (or to 60 when I'm playing a 60-locked game

This would not be a problem, but the stream is stuttering every ~1.5, ~2 seconds when this happens.
I've tested other streaming services, and I confirmed it's not happening to them.

That doesn't sound right. Did you restart Sunshine after applying the change (Sunshine does not re-read the config after startup)? What version of Sunshine are you using?

In any event, the setting will not really give you a floor of 60fps, more like ~30.

If you're getting 9 fps with this setting at 3, you have something else going on. Perhaps network issues, or something else completely. This issue is also about static content, such as sitting at the desktop screen or a menu with no animations. If you're in the middle of a game and having this, it's an entirely different thing.
