When these values are non-zero, the content cache is working.Īmount of data the content cache has served from its cache. Otherwise Instrument's 'time spent' metrics might be the next best thing, which requires you to compile OBS locally and attach Instruments to the process to check the time spent in different call stacks.Total amount of data the content cache has served. If somebody has more resources on how to accurately track performance on a mixed-core architecture with varying clock speeds of CPU and GPU cores, I'd be thankful. OBS' own render process will of course occupy the GPU more if it pushes more pixels at a high frame rate and minimising the main window at the very least should remove the need of the GPU to run colour conversion of OBS' main window (as we force Qt to use sRGB instead of the display colour space for the app surface). The occupancy itself is not surprising as WindowServer has to push the same amount of pixels to the screen constantly - if you don't have ProMotion the refresh rate would also not change. Launch OBS on an M1 Max with the above settings.ĭid you also track the clock speed of the GPU? Because 30% by itself doesn't give the full picture if the GPU was running at lower clock speeds.enabled the hardware encoder option and selected native resolution for both streaming and recording.Īctivity monitor shows a similar picture:.This usually consumes less than 5% of the cpu and gpu while idle. I have a few extra apps open (VSCode, terminal and a browser with 5 tabs).OBS's in-app cpu-usage-monitor shows 8% usage (on avg approx).By idle I mean, I'm not streaming or recording.

I have OBS installed on an Apple (M1 Max) MacBook Pro and noticed the idle cpu usage stays at 21% (approx) and GPU usage at 70 %. So, I'm not sure if this is normal behavior. PS: I'm (kind of) new to the video streaming space i.e. I was expecting lower CPU and GPU usage when idle. Please let me know if this needs to go some place else. This is (more of) a question than a bug report but I couldn't find an appropriate place for this, so thought I'd put it here.
