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 requires driver versions newer than 582.16/580.126 (Windows/Linux). Older drivers will log an error and abort the render. Note that you can use New Feature Branch drivers.
- On Linux, we recommend 590.48 or higher drivers.
- On Windows, we recommend 591.28 or higher drivers.
Intel OIDN GPU support is limited to:
- macOS
  - Apple native CPUs (M1 and newer)
- Linux
  - NVIDIA GPUs using Turing or newer architectures
- Windows
  - Intel Xe dedicated and integrated GPUs
  - NVIDIA GPUs using Turing or newer architectures
  - AMD GPUs with RDNA2 (Navi 21 only) and RDNA3 (Navi 3x) architectures
