OBS recording has low frame rate but low CPU usage

[Itz.Krayon]

Hello guys, i've been trying to get OBS to record 1080p 30fps for the past 3 weeks and every time i do the video is always stuttering, but my game is running a perfect 60 fps, my resolution is also 1080p. My CPU usage averages when recording around 35-40 percent and I have a Ryzen 1500x. OBS says its using  5-10% when recording but but its the video stutters a lot. Im using h264 AMD encoder while using the YouTube preset at balanced quality. My bitrate is 9000 and I dont understand what could be wrong.

 

~thanks in advance, Krayon.

 

here are my specs

 

 

Windows 10 Home 64-bit

16.0GB Dual-Channel 3000MHz

4096MB ATI Radeon RX 460 Graphics

AMD Ryzen 5 1500X

931GB TOSHIBA DT01ACA100 (holds operating system and applications)

2794GB TOSHIBA DT01ACA300 (holds games and recordings)

If you cant get OBS to work you can try AMD relive first.

If you're using the AMD encoder then it's encoding with your graphics card not your CPU. You need to set it to x264 to use your CPU.

You need to chage the process priority but expect the game to run worse with x264 CPU recording.

Not sure about the AMD one.

Yes, that is a fair idea and it works just fine, but the problem is I wanted to use obs' plugins to get rid of fan noise which is quite annoying.

The h264 codec is a CPU encoding codec right? I thought h265 was the only one that used GPU.

I've had the process priority set to high, and the problem still persist, although i did try x264 and although i've had zero frame drops, the stuttering still persist on the video.

H.264 is a type of compression algorithm. x264 is a codec that runs on the CPU and compresses video with H.264. The AMD H.264 encoder is a codec that uses the AMD GPU to compress video with H.264.

Using x264, what is the CPU Usage Preset set to?

ah, okay.

That takes some serious hardware actually  Set it to veryfast at least, or faster if you still get stuttering. You could probably lower the bitrate if you wanted to make smaller files, I use 10,000 kbit/s and veryfast for 1440p 60 fps recording and it looks great. For 1080p 30 fps probably could get away with 5000 or 6000 or perhaps even lower, though I haven't experimented much in the lower range. Might be worth doing a few tests though.

Ah okay, thanks, will try!
