Encoder Overload/Frame Problems with OBS

[Dwan]

Hello to the OBS forum.

I have been trying to figure out the best OBS settings for recording that goes well with my PC's capabilities, but I have not found a suitable one that gave me no frame problems or overloaded encoder warnings. Therefore, I found myself here looking for assistance.

You will see below in order my Video settings, Advanced settings, and Recording Output settings. I would like to note here that these settings have been the only settings that went well enough. Although it does not overload with these settings, I still have problems with frames with them as the frames appear lower than 60 in the recording (which is bad) when I play any game at 165 (it overloads when I switch to 165).

Here is the link for the latest log file where I tried using 165 frames with 2K output and 50000-70000 VBR: https://obsproject.com/logs/mfVydaM3aKq0rS8Y

I have tried CQP, VBR, and CBR with the given settings in the screenshots, but all of them gave same results with bad frame performance. It overloaded every time that I increased the frame number (120 and up).

No overloading occurs with any frame setting when Output resolution is set to 1080p, but that is not something that I want.

My PC specifications:
- MSI MAG Z790 TOMAHAWK WIFI 7200 MHz (OC)
- Intel i7-14700K
- NVIDIA RTX 4070 Ti Super
- 32 GB DDR5 6000 MHz CL36 RAM
- Windows 10 22H2
- 1 TB SSD
- AOC 24 inch 2K Monitor

Thanks in advance.

1. The Hardware-accelerated GPU scheduling ("HAGS") feature in Windows is currently known to cause performance and capture issues with OBS, games and overlay tools. It's an experimental feature and we recommend disabling it via these instructions.
2. Audio buffering hit the maximum value. This is an indicator of very high system load, will affect stream latency, and may even cause individual audio sources to stop working. Keep an eye on CPU usage especially, and close background programs if needed. Occasionally, this can be caused by incorrect device timestamps. Restart OBS to reset buffering.

Source affected (potential cause): Masaüstü Ses
3. One of your audio devices has a sample rate that doesn't match the rest. This can result in audio drift over time or sound distortion. Check your audio devices in Windows settings (both Playback and Recording) and ensure the Default Format (under Advanced) is consistent. 48000 Hz is recommended.
OBS Sample Rate: 48000 Hz
Mikrofon (Logitech G432 Gaming Headset): 48000 Hz
Hoparlör (Logitech G432 Gaming Headset): 44100 Hz
4. Framerates other than 30fps or 60fps, such as 165, may lead to playback issues like stuttering or screen tearing. Stick to either of these for better compatibility with video players. You can change your OBS frame rate in Settings -> Video.
5. Recording at a tremendously high framerate, such as 165, will not give you higher quality recordings. Usually quite the opposite. Most computers, such as yours, cannot handle encoding at high framerates. 98% of the time in your case. You can change your OBS frame rate 60 or 30 in Settings -> Video.
6. Having the YUV Color range set to "Full" will cause playback issues. Shadows, highlights and color will look off. In OBS, go to "Settings -> Advanced" and set "YUV Color Range" back to "Limited".
7. Multiple Game Capture sources are usually not needed, and can sometimes interfere with each other (scene 'Sahne':). You can use the same Game Capture for all your games. If you change games often, try out the hotkey mode, which lets you press a key to select your active game. If you play games in fullscreen, use 'Capture any fullscreen application' mode.
8. Your GPU is maxed out and OBS can't render scenes fast enough 0.2% of the time. Running a game without vertical sync or a frame rate limiter will frequently cause performance issues with OBS because your GPU will be maxed out. OBS requires a little GPU to render your scene.

Enable Vsync or set a reasonable frame rate limit (165, 120, 60, 30) that your GPU can handle without hitting 100% usage.

If that's not enough you may also need to turn down some of the video quality options in the game. If you are experiencing issues in general while using OBS, your GPU may be overloaded for the settings you are trying to use.

Disable Multipass and Psycho Visual Tuning in the encoding settings as those use additional GPU.

Please check our guide for ideas why this may be happening, and steps you can take to correct it: GPU Overload Issues.

If still having issues, post new log.

I have fixed the audio problems and although it requires a restart, I have turned off HAGS. Lastly, I have changed the color range from Full to Limited.

Considering that the only change is to the Color Range (as HAGS requires a system reboot to be disabled), it has affected everything for the better. It would normally stutter or screen tearings would occur while recording at 165 frames as you suggested, but there are no stutters or screen tearing with Color Range set to "Limited".

https://obsproject.com/logs/omDwOtBJgIvEkMqt This log has same settings as the one that I posted on the original post.
https://obsproject.com/logs/n1JoNY2LOEWtS80Y This is with Color Range set to "Limited"

Changing the color range decreased the GPU usage by 10 to 15 percent. I honestly did not expect a high-end product to fail me, and fortunately it is not failing me.

Thank you for your help, but do let me know if there is something wrong in these logs, especially the second. I look for optimum conditions to make use of OBS to its fullest.

Forgot to add: I could try disabling Psycho Visual Tuning or Multipass if I experience any stuttering or screen tearing, but it appears that changing the Color Range to Limited was the solution.
