New graphics card (upgrade) & cycles 2

Postby JOHNs3D » Fri Jan 11, 2013 1:51 am

Good day…
I posted a question here a few weeks back, and additional research after receiving a reply has resulted in a new question.
Does cycles use single precision or double precision floating points when doing its rendering?
A second question which I should've asked before but forgot about, many computers have more than one graphics card installed, is cycles capable of taking advantage of those multiple cards? Or does it render using only a single card even if others are available?
Have a nice day… John
