Why OBS Keeps Lagging?

Before getting started with the specific fixes to the OBS recording & streaming lagging issue, let's first look at the possible causes below:

✔ Insufficient system resources

✔ Unstable network connection

✔ Conflict with security software

✔ High-bitrate video streaming & recording settings

✔ Incorrect OBS settings

Furthermore, the cause could be the result of a combination of these factors. For example, if your computer's system resources are insufficient and the network connection is unstable, then OBS may lag while recording or streaming.

How to Make OBS Not Lag

If you want to make OBS less laggy while streaming & recording, just read this part to find the possible fixes.

1. Check Your Hardware

When you are facing a lagging issue in OBS, it is important to check your hardware. A damaged Ethernet connection, port, or router may influence OBS video playback. If they are loose or damaged, repair or replace them.

2. Lower the Amount of Bitrate

Some users tend to use a higher bitrate to improve the video quality of the recording & streaming content, which may lead to dropped frames and produce video lag. So we can lower the bitrate to solve the problem of missing frames, to avoid the OBS lagging issue.

Steps to lower the bitrate
Step 1. Launch OBS and go to the “File” > “Settings” > “Output” section.
Step 2. Find “Bitrate” and set the value to your requirements.

3. Ensure Stable Internet Connection

If the video is lagging or freezing in OBS, then you can check the internet connection. A stable and high-speed internet connection is essential to make your OBS perform well. Check your connection speed using any speed test tool. If the connection speed is slow, limit the usage, check your router, and make sure that the connection is stable.

4. Check the Security and Firewall of Your Device

Check if any security software is preventing your videos from playing properly. If the OBS lag issues persist despite having a stable internet connection, then uninstall the security software temporarily. You can also change the settings of your system firewall if it is interfering with the connection and making OBS lag. Just make sure the original setting is restored once everything is done. Also, you can disable the Firewall for your private or public connection.

Steps to change the Firewall settingsStep 1. Press the “Windows” icon (Start) and go to the “Settings” > “Update & Security”.
Step 2. Find and open “Windows Security”. Click on “Firewall & network protection”.
Step 3. Select “Allow an app through firewall” and select OBS from the listed apps.
Step 4. Press “OK” to save the change.

Allow OBS Through Firewall

You can also directly disable Firewall on your computer to allow OBS:
Just click on “Firewall & network protection” and select a network profile. Under the “Microsoft Defender Firewall”, switch the setting to “OFF”. Then your system and network can access any app that’s being blocked.

But it is still recommended to allow OBS through Firewall, instead of turning off the Firewall.

5. Stream on a Wired Connection

If your computer is connected to Wi-Fi, you may encounter the OBS lagging issue when streaming, especially when you are far away from the router since the wireless connections are not always stable or continuous. So you can stop the connection to Wi-Fi and connect the computer directly to the modem using Ethernet cable.

6. Update Network Adapter Drivers

Lagging in OBS streaming sometimes can also be caused by the outdated or corrupt network adapter driver. So users can check if the network card driver is up-to-date.

How-to update the network adapter drivers:
Step 1. Type in “Device Manager” in the Windows search box and click to enter the “Device Manager”.
Step 2. Select “Network adapters” and scroll to the network adapter name.
Step 3. Right-click the network adapter and select “Update driver” > “Search automatically for updated driver software”. Follow the steps and finally press “Close”.
Step 4. Restart your system after installing the updated driver.

7. Adjust the settings in OBS

The OBS recording setting can affect the recording experience and it varies on each different device. So you may need to play around with its settings to find the one that works best with your system to make OBS not lag.

How to adjust the OBS settings:

1>. Change Frame rate: Launch OBS and go to “File” > “Settings” > “Video Settings”. Find the “Common FPS Values”, selec your value, and hit “Apply.

2>. Change Resolution: Also go to the "Video Settings" tab from “File” > “Settings” path. Then select ans alter both "Base (Canvas)" and "Output (Scaled) Resolution".
You can match the Base resolution to your system resolution or downscale the output resolution for a better result.

Adjust the Resolution

8. Stop Other Bandwidth-intensive Activities

Applications that consume a lot of bandwidth might slow down your network and cause latency difficulties. So before streaming with OBS, ensure that all other resource-intensive programs are closed.

How to stop other bandwidth-intensive activities:
Step 1. Press “Win + R” to bring up the Run dialog box. Type in “resmon” and press “OK”.
Step 2. In the “Resource Monitor” window, switch to the “Network” tab and take note of the “Total (B/sec)” column.
Step 3. Right-click on the program that is eating up too much bandwidth and select “End Process”. Then press “End process” to confirm the operation.

Stop Other Bandwidth-intensive Activities

Note: Please make sure you know what sort of applications you’re closing. Do not stop any programs you are not familiar with in case you mistakenly end the crucial one, such as sychost.exe.

9. Reduce GPU Usage by OBS

OBS Studio uses the GPU to render the game scenes. But note that don’t make the GPU of your system run at more than 90% load since the fully utilized GPU can bring dropped frames to the recording. If the GPU load is over 90%, you can limit your in-game frame rate to make sure your game is running exactly at 30, 60, 90, or 120 fps.

Steps to limit the capture framerate in OBS:Step 1. Launch OBS and click the “+” button under the “Source” tab to add the “Game Capture” source.
Step 2. Follow the workflow to the “Properties” window. Scroll down and select the “Limit capture framerate” checkbox. (If you added the “Game Capture” in advance, you can select the “Game Capture” and click the gear icon to open the “Properties” window.)
Step 3. Press “OK”.

Limit the Capture Framerate in OBS

Keep in mind that reducing in-game detail or buying a high-end GPU won't fix the OBS game laggy issue unless you don't limit the fps.
