Question / Help CPU Load very high and over 2000 threads

[AlexH]

I do not understand why obs consume so many resources..

On my personal laptop 3 core and 8GB of RAM consumes up to 15% and on my dedicat server with 2 CPU and 24 core average is 70% and sometime even 100%.

I can someone explain why?

On my laptop o use windows 10 and on my server i try with windows 7, windows server 2012, windows 8.1, and same rezult, very big cpu load.

From your screenshot I don't see that obs studio itself causes any problem to your system.

And your renderer sucks as hell, look at log from this post: OBS Studio too heavy compared to OBS / QuickSync problems / Multi adapter problems possibly and compare to yours (Profiler Results in part of render).
