I have a old video card, but I wanted to try the GPU rendering. My card is CUDA 1.1, so I had to compile the kernel by myself:
- I am on a linux 64bit
- I installed the CUDA Toolkit from Ubuntu repositories
- I enabled CUDA on Blender user prefs / system
- I enabled rendering by GPU, Experimental and waited for hours the kernel to be compiled (while “optimizing a huge function” it filled my swap space although I have 4GB of RAM)… however, it got compiled at the end
There are two issues now: the first is that the GPU rendering is SLOWER than CPU rendering :-(… however, I suspect that this is “normal”, due to the old video card (an Nvidia Quadro NVS 135M)
The second issue is that since it took the whole night to compile this 1.1 kernel, I would like to save it somewhere… but I cannot find it in the blender directory: where is it?
Thanks to all those who answer
