OBS Studio How to Fix Dropped Frames

Drops in frame rate are an absolute nightmare for streamers. Usually, these drops are a result of bad OBS settings or a problem with your internet connection. In this tutorial, I’ll show you how to fix stuttering and dropped frames in OBS Studio.

#1 OBS Output Settings - Streaming

In OBS Studio, there are a few settings that we need to change or set. In the first method, we check the output settings.

Click on File in the top left corner, and after that on Settings.

Select the Output tab and change Output Mode to Advanced. In the Streaming tab, we can now change the Encoder. If possible, and if your card is powerful enough, change this to NVIDIA NVENC or RTX depending on your GPU. Otherwise, set it to x264.

Check the box next to Rescale output. Set it to 1920x1080 or 12-80 by 7-20. 12-80 by 7-20 is the safest choice to avoid stuttering. The lower the resolution, the easier it is to have a smooth running stream. The scaled resolution works best in a 16:9 aspect ratio.

Make sure that Rate Control is set to CBR. So as a rule of thumb, if you want to stream in 1080p and 60 fps, you should set the bitrate to at least 6000. For 1080p and 30 fps, you can set the bitrate to 5000.

For 720p and 60 fps set it to 5000 as well. For 720p and 30 fps lower it to 3000.

However, your connection needs to be fast enough to match this constant bitrate. If your bitrate is set to high and your connection can’t back it up, you will have frame drops and stuttering.

Next, adjust the keyframe interval to 2 seconds and the CPU Usage Preset to veryfast or to quality depending on your encoder choice. The last setting to change is Profile, set this to main.

Click on apply and it might be that changing these settings was enough to fix the stuttering.

#2 Deactivate Other Video Capture Devices

In the next method, we make sure that other video capture devices aren’t running in the background as this has a big impact on your CPU usage.

To change this setting. Double click on a video capture device. When it opens, check the box next to Deactivate when not showing. After that, click on Ok.

You have to do this for each source that you set in OBS.

#3 Network Connection

The next thing that you want to keep in mind is that streaming over WiFi can be unreliable as the signal strength changes constantly. When you live stream, you should try using an ethernet cable. If this stops the stuttering and dropped frames, you have an issue with your WiFi and you should try to use ethernet from now on.

When WiFi is the only option, try moving as close as possible to your router. If you are still having issues, it is a good idea to clear your DNS cache.

To do this, click on the windows search icon and type in CMD. Right-click on Command Prompt and select Run as administrator.

This opens a terminal window. Enter the following command: ipconfig /flushdns

When you enter the command, the DNS cache gets reset and hopefully, you fix any network related issue.

#4 Recording

Now for the recording settings. Again, click on Settings followed by clicking on Output. After that, click on the Recording tab. The first thing that you want to do is set the recording path to an SSD if possible and if you have enough room on it.

As a recording format, I advise selecting mp4. Same as before, set the encoder to NVIDIA NVENC if possible, otherwise, set it to x264.

Leave rate control on CBR or change it to CBR if it is set to something else. Bitrate should be fine, as long as it is above 10’000.

Set the keyframe interval to 2 seconds. Below that, set Preset to Quality and Profile to Main. The final setting to change in this screen is the Max B-frames setting. Set it to 2.

#5 OBS Advanced Settings

We are almost done with OBS Studio. There is one thing that we need to change in the Advanced Settings menu. Again, click on Settings.

Click on Advanced on the left side of the menu. Change Process Priority from normal to Above Normal.

Click on Apply and Ok.

#6 Dropped Frames - Updates and Location

In OBS, click on Help, followed by clicking on Check for Updates.

The next one to check is the server configuration setting for streaming. Click on settings once more, and select Stream. By default Twitch automatically chooses a server for you.

Click on the dropdown menu next to Server, and select the location nearest to you.

Another option to try is updating your graphics driver. If you use NVIDIA, you can use the GeForce Experience app. For AMD you can use the ADM Driver Suite.

This concludes our how to fix dropped frames in OBS Studio tutorial.
