Hi,

i'm actually working on a job with cycles:
With the 43098 build, one pict is rendered in 12 seconds.
With the last 43233 build, the same pict is rendered more then 30 secs.
My system:  2 GTX ( 1 gtx470-1mb and 1 gtx 285-2mb ) nvidia drivers 285 
on win7.
I was hoping the multiGPU to render 2x faster and not 3x slower :)

Hope it will help you...
=Thanks
