System Requirements
Autodesk 3ds Max 2019, 2020 or 2021.
Windows 7 or later, with the Visual Studio 2019 redistributable.
CPUs need to support the SSE4.1 instruction set.
GPU rendering requires an NVIDIA GPU of the Turing, Volta, Pascal, or Maxwell architecture. We recommend using the 451.77 drivers or higher. See Getting Started with Arnold GPU for more information.
