I do not have problem with cpu charge at the moment, but I wonder why GP displays systematically double of Windows 10 cpu charge.
Have you some info about it?
Gig Performer is displaying the percentage of CPU used for audio processing while the task manager on Windows displays this as a percentage of the overall CPU.
On a Mac - the “task manager” will display say 400% if you have 4 cores and all cores are 100% busy. On windows - it will display 25% if one of the cores is 100% busy for the same configuration.
