System Requirements
- 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.
- x86-64 CPUs need to support the SSE4.1 instruction set.
- 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 535.104 or higher drivers on Linux and 537.13, or higher on Windows. See Arnold GPU for more information.
