Browser Source CHokes the CPU

[glario522ac]

Without Browser Source the CPU is consuming 10% for all sources, but when I add 3 browser sources, that points to OBS Ninja to capture video. The CPU is going stuck in less than a minute; 100% usage and consequently everything is lagging.

The strange Behavior is when I'm taking a look to the CPU graphs. As you can see, it seems that the entire charge is going only on one of the nodes. I supose that all browser sources are using a single thread or single task process, in any case the slow down of using that component (browser source) is too much, even with scale down of resolution, frame rate control and other options available. No other source is consuming so many resources.

I'v read a lot of topics about that problem but didn't found any solution. Is there any development in direction to fix that problem?

Is this happening with or without hardware browser acceleration enabled?

This is one core out of 20. Windows seem to concentrate all load on one core to fully load it, so the others can sleep most of the time for power saving. 93/20= 4.65, so over every core it's about 4% more. If you have some computing intensive browser content, that's not too unexpected.

If this "93% CPU usage" is disturbing you, use some different usage reporting tool, since your tool seems to report the maximum usage of one core as overall usage, which isn't the real overall usage.
