Hardware Requirements

For hardware and software requirements of Corona Renderer visit our official website: Getting Started

Standard and legacy versions

Up to Corona Renderer 1.7 hotfix 2, the universal installer has contained two versions of the Corona Renderer plugin – standard and legacy:

  • The standard version uses SSE4.1 instructions set to achieve maximum speed on modern Intel (i3/i5/i7 or newer Core 2) and AMD (Bulldozer architecture and newer) CPUs.

  • The legacy version should run on all CPUs from the last decade, but it is about 20% slower.

From Corona Renderer 2 onward, the legacy version will no longer be offered, and you will need a CPU that supports the SSE4.1 instruction set (that is, any processor from within the last 10 years). Here is a list of compatible CPUs

From Corona Renderer 3 onward, the Licensing Server and the DR Server will no longer support CPUs without the SSE4.1 instruction set and are now 64-bit only applications (they will not run on 32-bit versions of Windows).

Optional: NVIDIA GPU AI Denoiser

To use the NVIDIA GPU AI Denoiser, you need an NVIDIA GPU with Kepler or newer architecture and the newest GPU driver. Not all mobile GPUs are supported.

Note: this denoiser type is optional, and Corona Renderer will work fine even if it's not installed (for example if you are using an AMD or integrated GPU). We also offer a Corona High Quality Denoiser, which utilizes purely the CPU, and this denoiser can be used on any computer which can run Corona Renderer. 

See: How to use denoising?


The amount of RAM you need to render your scene is purely dependent on the complexity of that scene. 

Generally, at this moment (2019), based on experience from user reports, we recommend 32 GB of RAM as minimum to render "standard" interior and exterior scenes. 16 GB would be definitely not enough to comfortably work with Windows OS and Corona Renderer. 

64 GB or more is even better, and the more RAM you can get, the larger and more complex scenes you will be able to render.

It is also important to optimize scenes to keep RAM usage as low as possible. See: I am getting sudden rise in RAM usage!
