Original GitHub issue: https://github.com/games-on-whales/wolf/issues/159

On the current stable build of Wolf as of 2/1/2025 there appears be some sort of delay in the video output to the input. In testing navigating the steam interface you can hear the navigational sounds immediately and the video output will then update date several seconds later.

The video feed itself looks perfect and even the stats for the stream show a locked 60fps and not packet loss or jitter. It seems like the video stream is very much several seconds behind the input.

For reference running on

AMD Risen 5900x
AMD 7900xtx
128GB memory
NVME storage
UnraidOS 7

Lowering the stream to 1080p it seems to work without issue, going to 1440p@60fps and above present the problem.

I've just pushed a fix that could potentially fix (or at least mitigate) this, you can update to the latest with:

docker pull ghcr.io/games-on-whales/wolf:stable

Let me know how it goes!

Just did a round of testing, looks like this has improve significantly audio, controls and video appear to be in sync. and all games playing well.

One thing I did note is that on all resolutions fps appears to be locked to 60fps despite moonlight being set to 120fps. For testing I did lower the resolution to 1080p as I know games can easily hit 80 - 100fps at that resolution, despite moonlight being set with or without vsync being enabled seemed to be locked to 60fps or below.

But no delays in video and controls were observed

This is to be somewhat expected.
The underlying issue is that the video encoding pipeline can't keep up with the amount of frames that we are outputting.

Before the fix, we were just accumulating the frames in excess, which will cause latency and delays at best and out of memory exceptions at worst.
Now, we are just dropping all the "extra" frames that are generated whilst your GPU is busy encoding so that you always get the latest picture.

So why is the video encoder that slow on AMD specifically? It's a mix of things:

The VAAPI encoder in Gstreamer is slower compared to Nvidia and Intel Quicksync. This might get better if and when the Vulkan encoders will be implemented.
We don't have a 0 copy pipeline (but I'm working on it https://github.com/games-on-whales/wolf/pull/156 )

With all that said I think that the original issue is fixed, so I'm going to close this 😉
