What is this thread for?
To post our findings on how to render the bunny on our GPU over the CPU.
What is the root cause of the error?
Your graphics card runs out of video ram (VRAM) before it can render the image.
How can we solve this?
It depends on your GPU and it may be that your GPU is simply not powerful enough to handle the particle systems used in this section. For this you will have to use CPU.
For my benchmark,
Rendered at 1920*1080 @ 100%,
Samples 128,
Tile size 64 *64.
This renders on a Nvidia Geforce 1060 GTX 6Gb, The change that was most significant in finding a resolution was the tile size which before was at 16*16.
If you find your GPU can render the image after playing with the tile sizes, please post your settings below to help others.
Good Luck and Thank-you.
