I made an audio reactive composition for a gig last weekend and am quite confused by the performance issues ive been having.
It runs fine off my 2 machines. (one is a MBP 15" 2.6GHz i7 running Yosemite, the other is much older MBP 2.66GHz intel core 2 duo running el capitan)
However i tried running the same composition on 2 much more highly specced machines (one a fairly new mac pro, the other a new retina MBP - don't have specs to hand right now) and they were struggling to push 4 fps.)
I saw a post somewhere which said something about shade with colour having problems with AMD graphics cards - is this still an issue? I tried dicosnnecting the shaders and this improved performance quite a bit on the mac pro (less so on the MBP) but was still not usuable.
Fine if i need to send some more details/specs - this is all i have to hand right now. -just thought i'd put it out there see if im missing somehting obvious.
