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.
- macOS 10.13 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.
- On Linux, we recommend 535.104 or higher drivers.
- On Windows, we recommend 537.13 or higher drivers.
- Intel OIDN GPU support is limited to:
- Intel Xe dedicated and integrated GPUs
- NVIDIA GPUs using Turing or newer architectures
