CPU Utilization on iMac in ExpressBurn Posted January 16, 2018 Is there a way for Express Burn to take full advantage of my iMac's i7 processor? When the software is encoding the video files (prior to recording the DVD) the CPU usage is at about 42-43%. I believe Express Burn is only utilizing 4 of the CPU's 8 cores. I have some other encoding software that is able to take full advantage of the i7 CPU and process the encoding at a much faster speed. Are there any updates planned for the software to take full advantage of today's faster processors? Thank you.
