Question / Help Why is my AMD H264 Recording super laggy?

[JhoNConners]

I have a R9 380x and I use it to record my games with obs. In most games, it is completely fine. But in Fortnite and R6 Siege, the recordings are super laggy, even though it's not like that for any other game.
Example: https://gyazo.com/30d1b3144fa0605c1d0cb8d641a3f61b
These are the settings that was recorded with, (https://gyazo.com/9cb75b496696b1e90cc6b75dc4f2cdae) and ive tried using other Rate Control Methods like CBR and it has the same result.
How would I fix this? Reducing the max frame rate to something lower than what I get in game would quite possibly work, but in these 2 games, you can't do custom framerate controls and usually they only allow 30/60/120/144 and my fps steadies around 100-120 fps and don't want to lower the cap to 60.

here it is, ran into a siege game and started replay buffer

You are overloading your system very badly.

Using Quicksync as encoder instead of AMD VCE may help (and gets you better image quality). If that doesn't fix your problem completely, limit the fps in your games with laggy recordings. There has to be a tiny bit of GPU resources available to OBS, because OBS does some image processing on the GPU. If the GPU is fully occupied by a game running unlimited, there is no GPU power left for OBS.

With AMD VCE, there is no dedicated portion of the video card for the encoder, so it takes up resources shared with normal gameplay operation.

I don't want to appear as wisecrack, but the wikipedia article about VCE says: "VCE occupies a considerable amount of the die surface", so it has some dedicated computing circuit.
On the other hand, all OBS logs tell that if the GPU is fully loaded, VCE is breaking down completely as well, so whatever is occupying die surface space, it isn't sufficient.

 

[Harold]

Except that in all instances I've seen, the VCE encoder will overload in sync with the main video card where nvenc won't under similar circumstances with Geforce GTX/Titan cards.

No matter what settings I use, quicksync looks like this which is why i dont want to use it,

windows media player or the films and tv app in windows 10 are both terrible media players to be checking recordings with.
Please check with VLC instead.

Doesnt matter what I check with, even in sony vegas and premiere, it looks the same, and even stays like that after rendering.

 

[Harold]

vegas and premiere are terrible at input format support as well.

 

[JhoNConners]

Then how would you propose me to edit videos made with quicksync? Use vlc and re-encode each and every clip?

 

[Harold]

If the videos play fine in vlc, then ultimately the problem is in the input format support of the other programs you're using.

They don't playback fine in VLC, theres less issues with the actual video but still issues. However windows media player seems to be fine with this particular clip for some reason
