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 12 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 590.48 or higher drivers.
- On Windows, we recommend 591.28 or higher drivers.
Intel OIDN runs on all CPUs. GPU support is limited to:
- macOS
  - Apple silicon GPUs (M1 and newer)
- Linux
  - NVIDIA GPUs with Turing, Ampere, Ada Lovelace, Hopper, and Blackwell architectures
- Windows
  - Intel Xe and Intel Arc dedicated and integrated GPUs
  - NVIDIA GPUs with Turing, Ampere, Ada Lovelace, Hopper, and Blackwell architectures
  - AMD GPUs with RDNA 2, RDNA 3, RDNA 3.5, and RDNA 4 architectures
