Hello. Firstly, my problem is not regarding rendering from the render que. It is about rendering frames in the timeline.
I recently upgraded from an i7 2600k to dual xeon 2690s (top of the line). In the after effects timeline (not the render que) my i7 would use 100% cpu to render the frame. However my xeons never go beyond 20%. In a complex scene they will literally sit there for 2 minutes on 9% cpu usage, drawing the frame. The i7 (using 100% cpu) renders the frame much faster!
In the render que it is possible to get my xeons to get to 100% using multi-processing, but it is unacceptable that this very expensive rig is far slower than my 2600k in the timeline. If i can't solve this problem i will have no choice but to abandon my xeons and go back to the 2600k.
Is anyone else running dual xeons in ae? Are you getting higher cpu usage than 20%? One possibility is that because my xeons are engineering samples from ebay they aren't as effective as retail. However maya utilises 100% cpu usage from them all the time. It's just after effects i'm having trouble with. Any advice is much appreciated.
