📎 AI Summary:
The thread discusses why video processing on Windows typically only reaches about 75% CPU utilization, with the original poster asking if they can increase it to 100%. HenkB explains that some tasks must run sequentially and that not all parts of a job can be parallelized, limiting CPU usage. Neemobeer suggests possible factors like power settings or thermal throttling that could also restrict full CPU utilization. The overall sentiment reflects curiosity about optimizing CPU load during intensive tasks, with expert insights into task parallelization and system constraints.

I don't understand why it hovers 75% average. This is doing video processing. Can I make it 100%? Thanks in advance.


An image from 'Why doesn't my cpu work at 100% for a lengthy big job?'. CPU performance in Task Manager shows AMD FX-8350 running at 27% usage, 1.36 GHz.

Not all subtasks of a job can be performed in parallel, some parts have to wait for the results of other parts. Look at your programs, you write them sequential, w.o.w filling just one processor, other processors may perform system housekeeping functions but these will probably not a produce 100% load. Modern compilers try to optimize programs, not all can be done.
