System Requirements
Maya 2020, 2022 or 2023
Windows 10 or later, with the Visual Studio 2019 redistributable.
Linux with at least glibc 2.17 and libstdc++ 4.8.5 (gcc 4.8.5). This is equivalent to RHEL/CentOS 7.
macOS 10.13 or later.
CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chip are supported under Rosetta 2 mode.
GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ampere, Turing, Volta, Pascal, or Maxwell architecture. We recommend using the 495.46 or higher drivers on Linux and 511.09 (Quadro), 511.09 (GeForce), or higher on Windows. See Arnold GPU for more information.
Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above.
The driver type must be set to DCH.
In the driver page, select "Windows Driver Type:" DCH
The cache will also need to be re-populated after installing a new Arnold version, updating to a new NVIDIA driver , or changing the hardware configuration of GPUs on the system. More information can be found here .
