Cycles modes?

Does anyone know how to switch between CPU mode and GPU mode is Cycles?

You need a Cuda-enabled build (there is a recent one on, but it was made before the commit that fixed the shading bug with chained add/mix closure nodes.

you also need a cuda enabled video driver: 270 or greater… and the build you have has to support your card… only some builds support them all…

I have a cuda enabled build

I’m updating the graphics driver so maybe that’ll work…

You also have a graphics card that supports the needed CC?

Yeah everything works now… Only gpu mode is slower for me and it crashes the display driver alot.
