In general, Arnold is going to work on pretty much any 64-bit system where Houdini, Maya, Cinema 4D, 3ds Max, or Katana works. However, there are some minimum requirements:
Note:
OptiX denoiser and GPU rendering require an NVIDIA driver version of 580.126 or higher (Linux) or 582.16 or higher (Windows). Driver versions below these minimums are not supported and will cause crashes. You can use New Feature Branch drivers.
Windows 10 or later, with the Visual Studio 2019 redistributable.
Linux with at least glibc 2.28. This is equivalent to RHEL/Rocky 8.
macOS 11 or later.
x86-64 CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chips are natively supported.
GPU rendering and Optix denoising work on Windows and Linux only, and require an NVIDIA GPU with the Maxwell architecture or later.
