If there’s not enough VRAM, then you can enable OctaneRender’s Out-Of-Core features.Īs OctaneRender does not use the CPU for rendering, a fast multi-core CPU is not required, but it does significantly improve scene-loading speeds.Ĭompute capabilities required for octane features: Compute CapabilityĦ.0 and 6.1 (eg: Nvidia Titan X, 1080, 1070) Therefore, this function is limited by the card with the least amount of VRAM. All textures, HDRI, geometry, and other scene elements must fit into a functional memory – each render GPU must have the same copy of all of the scene elements to complete the process. NOTE: Using multiple GPUs together combines the cores, resulting in a linear speedup, but VRAM is not compounded. The official list of NVIDIA CUDA-enabled products is located at. OctaneRender scales perfectly in a multi-GPU configuration and can use different types of NVIDIA cards at once - e.g., a GeForce RTX 2080Ti combined with a Quadro RTX 6000. GeForce cards are fast and cost-effective, but have less VRAM than Quadro and Tesla cards. GPUs from the GeForce® line are usually clocked higher and render faster than the more expensive Quadro® and Tesla GPUs. Texture limits and differing power efficiency ratings also apply depending on the GPU microarchitecture. OctaneRender also requires a minimum of 8 GB RAM, and we recommend 16 GB or more. RTX™ 20 Series, Titan RTX, GeForce RTX, and GTX 16 Series), Quadro® GPUs, Volta™ GPUs, GTX Titan (high-end), Pascal™ (GTX 10xx), Maxwell (GTX 7xx, GTX8xx, GTX9xx), and Kepler™ (GTX 680, GTX 690). OctaneRender requires the latest CUDA® 10 drivers and a CUDA-enabled NVIDIA® video card with support for compute capability 3.0 or higher.
