Very high GPU usage #236

Closed ranwer-dev closed 1 year ago

ranwer-dev commented 1 year ago

I have seen 1920x1080 screen recordings, without audio and with quality 70 and framerate 30, which takes almost 8% CPU & 30% GPU on my laptop. Whereas if I record the screen using FFmpeg, it takes 8% of CPU only, with No GPU used at all.

Why is this? Can we reduce GPU usage?

I'll run some profiling and see

Did you run profiling?

Yeah, it should be fixed in one of the recent commits. I've seen a drastic reduce in resource usage on my systems.
