Question / Help Troubles with AMD encoder

When I use the x264 low cpu encoder for record - fps in video stable. But if I use an AMD encoder, then the FPS on the video starts to drop and the video is very freezes. What is the problem?

P.S. Recently I reinstalled Windows. Before the reinstallation, everything was fine and the AMD coder worked stably. May be reason in new videodriver? Or, maybe there is something missing in the system?

Game mode and XBox DVR - disabled. Installed last chipset driver and videodriver, also last update windows 10. OBS version - 20.0.1. I tried to install an earlier version OBS - 19.0.2, on which everything worked fine before reinstalled the Windows, but it did not help.

I tried playing in Fallout Shelter, then Dead by Daylight.

GCN1/VCE1.0 cards require a rather high Keyframe Interval to work with Constant QP. At least 4 seconds, if not more.

But no one answered the main question. Why until the reinstallation of Windows everything was fine, but now everything is lags? And how to fix it?
All my previously recorded videos used AMD encoder and had stable 60 fps, now I can not record video this way (

I tried to change the resolution from 1920x1080 to 1280x720 and recording with AMD encoder works well. But why does it freezes at 1920x1080?

Simple, higher resolution means more data. More data means more time required to write things from RAM to disk. More time required means more freezing unless you reduce either the quality or figure out another way to get the desired results.

Earlier I used to use output mode: Simple. And now too. All videos on my channel recorded with thats settings in resolution 1920x1080 and 60fps (just to check https://www.youtube.com/c/Enotan). Then I was forced to reinstall completely windows. After that, I appeared this problem when recording...

I tried to record the video using ReLive. And FPS on video stable at 60fps and resolution 1920x1080. So the problem is in the OBS?

I am mostly a novice in this regard, but I would say changing to Same as stream and choosing 'Speed' as your Encoder Preset and retest if the recording comes out good. On the old AMD Branch of OBS Jackun had recommendations stating that GCN1.0 cards (I have a GCN1.1 which just means I get extra B-frames but otherwise we have a similar card) should use a setting of 'Speed' or 'Balanced'. I've been fiddling with these settings since then and can confirm that 'Speed' works the best for me in game and still looks good. Choosing a Bitrate might be difficult, but I recently redownloaded Metro: Last Light going through the benchmark and recording along the way and found a Bitrate that is favorable to me.

EDIT: Just saw your recent post. For me it has always been the opposite with a variable frame rate coming out of ReLive (among other bugs) and OBS keeping the outputted video at 60 even when my game wasn't getting 60.

Lol. Even if I record just the black screen with sound, the program drops fps.

Click to expand...

I had the same thing before. OBS had stable 60fps, even if in the game FPS did not rise above 40. And now just some kind of nonsense happens...

Noticed another strange thing. If the game is minimized and the record is turned on, then the video is stable.

Well, it worked. I deleted the latest version of the video driver and put the old one (from 17.7.2 to 17.1.1). Now everything works fine :)

Interesting. I didn't realize that there had been an update to AMD's display drivers. I think I'm going to clean install and check out this update since some of the highlights sound pretty enticing. Hope I don't recreate your problems. :P

EDIT: I'm thinking there may be only a couple of things that could cause the recording to have messed up for you just by looking at the highlights.
  • Optimized memory usage for lower overhead while recording or capturing.
  • Shader Cache is now supported for select DirectX®9 titles.
Other than those I don't know what else could have changed that could have messed this up. Testing, testing and more testing.
