Selecting a Render Device Different systems can produce different results with each render device. Try each render device before choosing a device that works for you. To select a render device: Click Tools > Options > 3D Viewport. Under Render Device, select: CPU, if your CPU is significantly more powerful than your graphics card. GPU, if you have a powerful video card such as an NVidia CUDA-enabled GPU with more than 1 GB VRAM. Hybrid, if you have a balanced system with a good nVidia card and a comparable CPU. For a complete list of rendering options, see the Render Tab . Parent topicPost Installation Tasks
