The main reason OBS becomes heavy is that the processing needed for streaming cannot keep up with your computer’s performance.<\/p>\n\n\n\n

By closing unnecessary tasks and reviewing the bitrate, you can achieve stress-free streaming.<\/p>\n\n\n\n

This article will explain appropriate solutions step by step to resolve issues such as “game streaming is choppy” or “delays in streaming.”<\/p>\n\n\n\n

If you are struggling with OBS becoming heavy quickly, let’s review the settings while using this as a reference.<\/p>\n\n\n\n

What could be the causes when OBS becomes heavy or choppy?<\/h2>\n\n\n\n

We have summarized three main potential causes when OBS becomes heavy or streaming gets choppy.<\/p>\n\n\n\n

Cause<\/th>Details<\/th><\/tr><\/thead>
OBS settings are overloading the PC<\/td>If the settings like resolution, frame rate, or bitrate are too high, it might overburden the PC.<\/td><\/tr>
Game settings increase the load<\/td>If having choppiness when streaming high graphics games, the game settings are likely the cause.<\/td><\/tr>
Unstable network environment<\/td>Slow connection speed or instability can also be a cause.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

For those who do not know which cause applies to them, we will explain how to explore potential causes in the next section.<\/p>\n\n\n\n

Identifying causes of heavy OBS with “Log Files”<\/h2>\n\n\n\n

OBS is equipped with a “Log File” feature that allows pinpointing issues with game settings, network environment, or insufficient PC specifications.<\/p>\n\n\n\n

The following explains how to use log files.<\/p>\n\n\n\n

Uploading Log Files<\/h3>\n\n\n\n

First, run the stream or recording for about 30 seconds. Even a short duration captures enough information, so you do not have to force a longer test.<\/p>\n\n\n\n

After that, upload the log file by following the steps below.<\/p>\n\n\n\n

1. Select “Help” from the OBS menu
2. Click “Log Files” \u2192 “Upload Current Log File”
3. Copy the displayed URL<\/p>\n\n\n\n

Check Errors with Log Analysis Tool<\/h3>\n\n\n\n

The uploaded log file’s error content can be checked with a dedicated analysis tool. Although the tool is in English, using the translation function poses no problems.<\/p>\n\n\n\n

The analysis results are divided into the following three categories.<\/p>\n\n\n\n

\"\u30ed\u30b0\u5206\u6790\u30c4\u30fc\u30eb\u3067\u30a8\u30e9\u30fc\u3092\u78ba\u8a8d\u3059\u308b\"<\/figure>\n\n\n\n
Analysis Result<\/th>Analysis Details<\/th>Example of Trouble<\/th><\/tr><\/thead>
Critical<\/td>Problems directly impacting streaming or recording are displayed as “Critical” in a red box.<\/td>GPU hardware acceleration is not functioning properly.<\/td><\/tr>
Warning<\/td>Areas needing review are displayed as “Warning” in an orange box.<\/td>OBS sampling frequency doesn’t match the audio interface settings.<\/td><\/tr>
Info<\/td>Supplementary information on OBS operating environment and settings is displayed in a blue box.<\/td>Bitrate is low.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The URL of the analysis results can be shared with others. If you find it difficult to solve on your own, sending the URL to someone trustworthy with knowledge is a good option.<\/p>\n\n\n\n

Solution for Heavy OBS \u2460 Optimize OBS Streaming and Recording Settings<\/h2>\n\n\n\n

Once the cause of heavy OBS is identified with log files, review the settings in the following order to optimize streaming and recording settings.<\/p>\n\n\n\n
