[Bf-cycles] Issue with rendering using GPU's

[Gottfried Hofmann]

Try to render the scene with Blender 2.69, there is a chance that the 
error will not appear with the older version.

He is trying to run a scene that renders fine one a card with 2GB on a 
card with 6 GB and runs out of memory. I got the same problem here:

In Blender 2.71 and 2.72, rendering a scene that renders fine on my 2 GB 
730M runs out of memory on my 3 GB 580 GTX. Rendering the scene on 2.69 
is usually the solution. There seem to be big issues with Fermi based 
cards in recent releases :(

Cheers,
Gottfried Hofmann
