I am being bothered with a very annoying issue.

When i try to record my screen with obs or share it with discord i experience a lot of lag in a game I’m playing. This occurs with every title i have tried(Apex legends, minecraft, Shadow of the Tomb Rider, Lol)

I dont know if this has anything to do with it but when i try to use pipewire to capture screen in obs it does not work(it does not allow me to select a screen to capture:)

XSHM works but it causes the lags, discord capture too. (My fps drops from ~120 to ~65) and the game feels really choppy.

Pipewire is a sound server AFAIK.

So why there is an option in obs to capture video via pipewire?. And how to fix the performace of other options

AFAIK is AFAIK. So what’s your explanation? What has your online research found? What have you read and what else have you tried? What were the results?

I have tried installing the NVFBC plugin for obs but later realized that i would need to downgrade obs to do that. It is really hard for me to research this since everything i find on the internet is related
to wayland.

OBS can do a lot. Maybe the PipeWire thing is just for doing an audio-only capture. I agree that “screen capture” does not make sense if it is only audio, but perhaps it is just a name inherited from the primary feature.

You should not expect to get your full FPS when you are running a full-blown screen capture utility, it’s never going to happen. If you need the maximum performance from your computer while you do the game, you are going to have to get an HDMI capture card. Most of the videos you see online where people stream their games will use a setup like this (not screen capture software running on the same device).

You’re absolutely right about Pipewire’s video involvement. Here’s the (Arch) authority. I note the information is rather sparce, but the links aren’t. :slight_smile:

https://wiki.archlinux.org/title/PipeWire#Video

The first line is, “Although the software is not yet production-ready, it is safe to play around with.”
