As I said in the title Blender switches from GPU tu CPU everytime I start a render.
I set my render device to GPU, I start the render, it renders in GPU and automatically switches the device to CPU.
I must have changed something since it wasn’t doing this this morning.
and it does it even in a new file.
When I start a render in CPU, it doesn’t switch back to GPU though.
I tried deactivating all the add-on I activated But it didn’t do the trick
I have Blender 2.71 running on windows 7 (64 bits)
GPU : Geforce GTX 650 Ti
CPU : i7 4770k
RAM : 16 GB
