using Motion 5 to match move a computer screen (4 corners) today, I was surprised how slow it was.
I am used to Motion 4 on a 3 years old MacPro with 8 Gigs of ram being very fluid in positioning the tracking points. This same operation on my new iMac with 32 gigs of Ram was painful as each tracker seemed stuck when moving with the mouse. I ended up moving them with numerics.
Tracking itself (analyze) was as expected though. Anybody has seen this before?
