Description

OBS stutters a lot when recording specifically gameplay. These stutters are shown both in the recording and in the preview even before recording starts. This issue appears to be unrelated to framerate, as setting the monitor's refresh rate in the hyprland.conf file to 60.00Hz does not fix this issue. I'm also pretty sure this issue is Hyprland Specific. I tested the same scenario on the Cosmic Alpha and it worked as expected. I'm also not sure if this is due to something Xwayland does. Also, the game only stutters IN the recording. While playing, nothing seems off except OBS's preview and the recording.

How to reproduce

Open Hyprland
Launch OBS
Start recording with OBS
Launch game.
Play game for any length of time
End Recording

This recording should have a ton of stutter.

Crash reports, logs, images, videos

Below is an example of this issue in subnautica.

Here too mydude, but the games stutter without opening OBS.

Aug 26 '24 10:08 ENDragnee

test disabling

render{
# Enables explicit sync support.
 explicit_sync = 1
}
render:explicit_sync = 1

why do you even have the second line in your config ??

additionally, you could play around with

no_hardware_cursors
 no_direct_scanout

Aug 26 '24 11:08 romanstingler

I am also experiencing a similar issue with recording stuttering.

To add to this now that I have gotten home. The above does not seem to relate to me as I do not have the "render {..}" code block.

I am going to test around with the no_hardware_cursors as well as no _direct_scanout to see if they make any differences.

I have tried downgrading to a different OBS version through AUR and the current OBS version I am on is: "30.2.3-tytan652-1 (64 bit).

I may bounce around and test other version per this GitHub posting: #7640 which someone mentions a 0.41 the error happened then or before then.

I will keep this updated here if I find anything but may take time due to work :)

Sep 09 '24 21:09 JaredKIso

render{
 explicit_sync = 1
}

It actually works! I have the same problem and my previous settings is explicit_sync = 0, after I set the explicit_sync to 1 ,the problem disappear and everything goes fine

Sep 11 '24 08:09 EmmetZ

I was testing around a bit more last night and found the following:

The stuttering does not happen when recording just the desktop.

The game I was experiencing this issue on was a game that I had set to Vulkan for rendering. After changing it to Direct3D 11 I testing recording the game again and I did not experience the issue anymore. (For context I am playing Deadlock).

I was doing further research and it looks like this (if related) has been a known issue for a bit regarding Vulkan: https://obsproject.com/forum/threads/i-cant-capture-vulkan-games-i-can-no-longer-hook-vulkan-games-i-could-but-now-i-cant.143257/

From that comment section I saw someone mention the use of "Game Capture" which my OBS does not have. This lead me down the path of: https://www.reddit.com/r/linuxquestions/comments/x0q6fp/obs_game_capture_on_linux/

Which then linked to: https://github.com/nowrep/obs-vkcapture?tab=readme-ov-file

I will be testing this today and will keep everyone updated!

--

T.L.D.R:

From my testing in game Vulkan rendering was causing issues. After swapping the game back to Direct3D 11 I no longer experienced the issue. Did some more research and found that this has been known a while ago (2021) and to use game capture in OBS. Testing today how to get https://github.com/nowrep/obs-vkcapture to work properly.

I am also going to test around a bit more with explicit_sync as it worked for Emmet :). So I will post here about how each thing goes

Sep 11 '24 14:09 JaredKIso

Here to post an update!

Regarding my previous post I will get what did not work out of the way:

---| Things that didn't work |---

Downgrading OBS
Updating system (Even a fresh install)
Trying the suggestions that @romanstingler suggested neither of them worked for me but did for @EmmetZ.

Because these didn't work I had to dig a little further into it.

To cut to the chase: ---| What worked for me |---

Noticed that if I swapped to Direct3D 11 for the game that saw stutters the stutters no longer happened in recordings.
Found out the stuttering on recordings was a known thing for Vulkan.
Someone suggested adding a Vulkan game capture to OBS. (https://github.com/nowrep/obs-vkcapture) --- Quick Solution: ---
Installed it via yay -S obs-vkcapture-git
Added obs-gamecapture OBS_VKCAPTURE=1 %command% to the games "Launch Options" on steam.
Set the games render to Vulkan and tried recording using "Game Capture" and it worked smoothly!

Hope this helps someone else if they experience this issue!

Sep 12 '24 05:09 JaredKIso

I encounter the same issue, but in Vesktop. This solution as I understand only works for OBS?

Here to post an update!

Regarding my previous post I will get what did not work out of the way:

---| Things that didn't work |---

* Downgrading OBS

* Updating system (Even a fresh install)

* Trying the suggestions that @romanstingler suggested neither of them worked for me but did for @EmmetZ.

Because these didn't work I had to dig a little further into it.

To cut to the chase: ---| What worked for me |---

Sep 19 '24 12:09 LaineZ

@LaineZ I do think this is specific to OBS (my solution).

But, I do recall seeing stuttering on different distros. When I swapped from Nobara to CachyOS (Hyprland specifically) it went away. I do not know why, could be drivers or how Vesktop interacts with the WM.

Maybe that is the place to investigate :)

Sep 21 '24 06:09 JaredKIso

@JaredKIso Probably you are right. I didn't remember any screenshare issues on OpenSUSE Tumbleweed, but there is also involving Plasma DE. I didn't test hyprland in OpenSUSE

Sep 21 '24 19:09 LaineZ

For me, enabling render:explicit_sync = 1 seems to be resolves this issue (Both in OBS, and Vesktop)

Hi there! Joining the thread. Enabling render:explicit_sync = 1 resolves this issues but ONLY in OBS, Vesktop still having stutters. Will be posting my findings here.

i also get stuttery recordings in OBS with explicit_sync = 0, and the game i use to test this (ULTRAKILL, dxvk, offloaded to the GPU, VSync enabled) doesn't stutter.

enabling explicit_sync = 1 makes the game itself stutter but recordings don't stutter anymore.
recording the game with obs-vkcapture with explicit_sync set to either 0 or 1 doesn't stutter (but vkcapture can't record everything so this isn't a good solution for me)
with explicit_sync = 1 again, disabling VSync gets rid of the stuttering. this solution doesn't work everywhere either because some games don't give a max FPS select screen and force VSync on the player, e.g. Manifold Garden — trying to use gamescope to force the max FPS doesn't work because gamescope or the game seem to crash? (but that's another issue)

Here's what I ended up putting into my hyprland.conf. No screen share stutters in OBS or Vesktop. All games works smooth as well.

render {
    explicit_sync = 1
    explicit_sync_kms = 0
}

I had to reboot for the changes to take affect.

Hi, explicit_sync also fixed the issues in obs for me. But even on the latest hyprland-git and 565 nvidia drivers, I still find explicit sync buggy.

So I also recommend using obs-vkcapture-git, which @LaineZ posted about earlier. Also for Vesktop issues like @TheCliffRacer has, please note that the latest discord-canary has native support for wayland screenshare, which I have no issues with.

@EnderMaster77 this should be fixed with both and without explicit sync in git, if it is you can close this issue

I can confirm latest git works fine and the stutter is gone. I had to use vk-capture before but now it works just fine without. I tried with explicit sync on and off and saw no stutter.
