Last February I worked on a project with a brand new 15" Mac Book Pro. The night before the show - videos started lagging/freezing and the CPU usage was spiking close to 140%.
I was basically running a four channel mixer style interface, with a mask- then running Syphon out into Madmapper for geometry correction. Then that was feeding a Matrox Triple Head to Go DP edition.
But it seemed like the computer was trying to render everything on the CPU rather than the GPU-
1. Is this a potential Iris issue,
2. Would ripping all of the video content to HAP files help?
Was running VDMX b0.8.5.0.7
MadMapper 2.2.5
Mac Book Pro (Retina, 15-Inch, Mid 2015)
OS X 10.11.12
2.2 Ghz Intel Core i7
Intel Iris Pro 1536 MB
Because it took me more time than planned to sort that out- we had to can sequencing control of the show and Ableton- I basically triggered ISF, and QC effects live. That typically used less than 50% of the CPU.
Any ideas?
