The most critical parts of your system to run and record EboSuite smoothly are the GPU, the CPU and the hard disk, since reading the video from the disk and unpacking the video files (on the GPU) and writing the video stream to the disk and compressing (on the CPU) are the most intensive processes. The Intel Iris Pro is an integrated graphics card, not a dedicated graphics card (GPU), so that is not optimal and that will affect your recordings. You could try recording with QuickTime player 10 (‘New Sceen Recording’, under File), since Syphon recorder creates an extra OpenGL texture and therefore is more demanding on your GPU than QT10. Be aware that QT10 recordings are much bigger when recording on a retina screen, so you might need to record a smaller output window, to get the size your aiming at in that case. I strongly recommend to use an SSD disk, because the system is reading and writing from disk while recording, so disk speed has a big impact on the quality of the recording. You could try using H264 videos in EboSuite instead of Hap videos, because they are much smaller (so easier to read from a non-SSD drive) and are not decompressed on the graphics card. Ofcourse turning of some eFX or video tracks in Ableton or choosing a smaller output window size will also lead to smoother recordings, but that probably has unwanted effects on your composition.
