I'm currently converting some films to ipad format using HandBrake. The CPU is going full speed according to Active monitor at 720%, and istat menu is reporting 97% usage with all 8 threads. However, I'm only getting average 60 fps in handBrake. With my old i7 960 (3.2GHz) Windows 7 PC, I'm used to getting 80 to 100 fps at only 30% CPU usage. In fact I use to open 3 separate HandBrake conversions at the same time with higher fps than I'm getting now on the imac. I don't have Bootcamp installed at the moment so can't test HandBrake in Windows. Does everybody else also getting the same fps or are your's is much higher? Thanks Edit: I'm mainly converting from 720p films around 8 to 10 Gb.
