    3. Fix hardware issues

When trying to fix lagging in OBS, do not ignore the hardware issue. Faulty Ethernet cable, port, or router may interfere in the smooth playing of OBS videos. Fix or change them, if you find them loose or damaged.

    4. Stream on a wired connection

Wireless connections are not always stable or continuous. Disconnect from your router and connect the computer directly to the modem using Ethernet cable. Streaming on a wired connection is better and assures continuous network.

    5. Lower bitrate

Streamers tend to use higher bitrate to enhance video quality but this leads to dropped frames. If you drop too many frames, you may lose connection with the server. Lowering bitrate stops the issue of dropped frames, thus preventing video lagging in OBS. At times when the network issue cannot be fixed, lowering bitrate is helpful.

   6. Change OBS setting as per your computer

OBS recording settings vary with every computer. You may have to play around with its settings until you find the one which works the best on your system.

Below is the preferred setting for 1080p and 720p computer resolution. You can fix the OBS video freeze and lagging issue by changing to these settings in the OBS.

Settings to change on computer with 1080p resolution: 

  • Visit Settings > Encoding (in the sidebar menu)

  • Update the FPS field to 60. If you continue to experience lagging, lower the FBS to 30.

Once you have changed the settings under Encoding, reset the Advanced settings.

  7. Check your firewall and security software

9. Reduce GPU usage by OBS

OBS program uses the GPU to render your games scenes. But to do this without dropping frames, it should not be fully utilized. If your OBS games are stuttering, show fps drop, or are not streaming due to lagging issues, make sure the GPU of your system is not running at more than 90% load. You can monitor your GPU load by using GPU-Z.

If the GPU load is between 91-100%, then limit your in-game frame rate (fps). Make sure your in-game fps is running exactly at 30, 60, 90 or 120 fps, as required.

If the GPU load is not more than 90 %, then this game is running on a CPU limit.

Steps to limit capture framerate in OBS

  • Open OBS.
  • Go to your sources at the bottom.
  • Right-click on your game capture, and hit Properties.

Properties for Game Capture Window

  • Select ‘Limit capture framerate’ checkbox.
  • Click OK.

Remember, reducing in-game details or buying a high-end GPU will not fix game lags in OBS, unless you don’t limit your fps.
