Qualified Operating Systems

macOS Monterey (12.x), or macOS Ventura (13.x). Nuke 15.0 supports Apple's silicon hardware on M1 and M2 chips.

Article:  For more information on Foundry products and supported macOS versions, see Foundry Knowledge Base article Q100592.

Windows 10 (64-bit) or Windows 11 (64-bit)

Linux Rocky 9.0 (64-bit)

Warning:  Nuke requires libnuma to run under Linux distributions, the library is required by the Nablet H264 Codec SDK.

Note:  The currently supported version of VFX Reference Platform includes library versions that are only compatible with Rocky 9.0.

Other operating systems may work, but have not been fully tested.

Requirements for Nuke's GPU Acceleration

If you want to enable Nuke to calculate certain nodes using the GPU, there are some additional requirements.


An NVIDIA GPU with graphics drivers capable of running CUDA 11.8, or above. A list of the compute capabilities of NVIDIA GPUs is available at

Note:  The compute capability is a property of the GPU hardware and can't be altered by a software update.

With graphics drivers capable of running CUDA 11.8, or above. On Windows and Linux, CUDA graphics drivers are bundled with the regular drivers for your NVIDIA GPU. Driver versions 522.06 (Windows) and 520.61.05 (Linux), or above are required. See for more information on compatible drivers.

Note:  We recommend using the latest graphics drivers, where possible, regardless of operating system.


Note:  Bitwise equality between GPU and CPU holds in most cases, but for some operations there are limitations to the accuracy possible with this configuration.

On Windows and Linux, an AMD GPU from the following list:

Note:  Other AMD GPUs may work, but have not been fully tested.

AMD Radeon PRO W7900

AMD Radeon PRO W6600

AMD Radeon PRO W6800

AMD Radeon Pro W5700

AMD Radeon RX 6800 XT

Note:  For information on the recommended driver for each GPU, see

On Mac, integrated AMD GPUs are supported on the following Intel CPU Macs:

Any late 2013 Mac Pro onward (including 2019 Mac Pro),

Mid-2015 MacBook Pros onward, and

Late 2017 iMac Pros onward.

All supported Mac Pros include a multi-GPU support option, where applicable. Bitwise equality between GPU and CPU holds in most cases, but for some operations, there are limitations to the accuracy possible with this configuration.

Warning:  Although AMD GPUs are enabled on other Mac models, they are not officially supported and used at your own risk.

Multi-GPU Processing

Nuke's GPU support includes an Enable multi-GPU support option. When enabled in the preferences, GPU processing is shared between the available GPUs for extra processing speed.

Note:  Multi-GPU processing is only available for identical GPUs in the same machine. For example, two NVIDIA GeForce GTX 1080s or two AMD Radeon™ Pro WX 9100s.

GPU Requirements for the Machine Learning Toolset

Training using the CopyCat node requires an NVIDIA GPU, with compute capability 3.5 or above; or MacOS Apple silicon integrated GPUs.

If an appropriate GPU is not available, Inference and other machine learning plug-ins can run on the CPU with significantly degraded performance.

Developer Notes

As Nuke develops, we sometimes have to make changes to the API and ABI under the hood. We try to keep these changes to a minimum and only for certain releases, but from time to time API and ABI compatibility is not guaranteed. See the following table for the situations when you may have to recompile your plug-ins and/or make changes to the source code.

Release Type






14.0v1 to 14.0v2





14.0v1 to 14.1v1




14.0v1 to 15.0v1


Additionally, node Class() names occasionally change between major releases. While these changes do not affect legacy scripts, you may not get the results you were expecting if a node class has been modified. The file, used to create Nuke's node toolbar, contains all the current node class names and is located in <install_directory>/plugins/nukescripts/ for reference.

As an example, between Nuke 13 and Nuke 14, the Axis node Class() changed from Axis3 to Axis4. In the file for the two releases, the entries for the Axis node appear as follows:

m3Dclassic.addCommand("Axis", "nuke.createNode(\"Axis3\")", icon="Axis.png", tag=MenuItemTag.Classic, node="Axis3", tagTarget=MenuItemTagTargetFlag.TabMenu)

m3D.addCommand("Axis", "nuke.createNode(\"Axis4\")", icon="Axis_3D.png", tag=MenuItemTag.Beta, node="Axis4")
