Autodesk built Arnold GPU on the NVIDIA OptiX framework to take advantage of NVIDIA RTX’s RT Cores for dedicated ray tracing and Tensor Cores for AI denoising. Several performance improvements to help maximize efficiency, including faster creased subdivisions, an improved Physical Sky shader and dielectric microfacet multiple scattering. This is especially useful when working with dense, asset-heavy scenes where memory limits can be reached quickly. With NVIDIA RTX, improved Smooth Mesh Preview support that now uses less memory and runs previews on the GPU when possible. With NVIDIA RTX, Autodesk Maya 2020 delivers new GPU-accelerated features, including New Proximity Wrap deformer that provides better memory use and a significant performance boost to artist workflows, making it easier to achieve smooth results. Unified renderer that allows users to switch seamlessly between CPU and GPU rendering. Yes, as we analyzed in the previous parts, artists will be blown away by the new interactivity and unmatched speed of rendering using Multi RTX GPUs in Autodesk Arnold 6. And below are some reasons why Arnold GPU is pleased for Maya users and increasingly popular in the 3D graphics community? In the rendering space, the idea of offloading certain tasks to the GPU has been around for over a decade, but it’s only been in the past few years that you’ve seen massive leaps in performance, largely thanks to NVIDIA’s advances with their Ampere architecture and RT cores. There is no hybrid rendering (CPU+GPU) option. CPU render, use (at least): Camera (AA): 3~4, Max Camera (AA): 30~50, Adaptive Threshold: 0.015~0.02 There is no AMD Radeon support with Arnold GPU. NVIDIA GeForce/Quadro driver 419.67+ required. Best performance will be seen after using the ‘Pre-populate GPU Cache’ utility. Arnold GPU (currently) uses only Camera AA sampling. If you’d like to jump aboard the Arnold GPU train, here are some important things to bear in mind: īut, for best performance, Arnold recommends using Ampere RTX. 
You can see the full list of supported GPUs. Generally, any GPU based on the Maxwell architecture or newer (Pascal, Volta, Turing, Ampere…) will work with Arnold if paired with new enough NVIDIA drivers.
– Video card: NVIDIA card of the Turing, Volta, Pascal, and Maxwell architectures. – Processor needs to support the SSE4.1 instruction set. For the hardware, Arnold GPU users can easily choose their machine configuration with the minimum system requirements as below: Arnold GPU is available in all supported plug-ins: Autodesk Maya, Autodesk 3ds Max, Houdini, Cinema 4D, and Katana.
