Supported Operating Systems

Windows 7, 8 and 10 (32 and 64-bit) are supported.


Comment for MAC OS systems: ReluxDesktop cannot be run natively on MAC OS or other Linux derivatives. 

On these platforms it runs only inside an emulation layer called Virtual Machine. 

To be more precise, a MS Windows Virtual Machine must be created using visualization software such as Virtualbox.

Supported Graphics Cards

video memory (VRAM): 

minimum 512 MB.

optimal: 1024 MB or more.


at least OpenGL version 3.0 is needed.

  • AMD Radeon or better
  • Nvidia GT 650 or better

Note: ReluxDesktop tries to detect potential graphics card incompatibilities by switching to Mesa mode. 

Mesa mode processes 2D and 3D visualisation as a software emulation, which means the hardware acceleration of the graphics card cannot be used. 

The advantage of this mode is its reliability. The downside is slower execution of ReluxDesktop. 

This mode can be activated manually in ReluxDesktop via Extras->Options->General settings.


Main memory (RAM)

Minimum required: 2 GB RAM

Optimum: 4 GB RAM or more


ReluxDesktop is a 32-bit program. This means the program can use 2GByte RAM at most. 

One exception is the standard calculation engine for artificial and daylight calculations. 

This can use the entire main memory of 64-bit operating systems, and thus makes it possible to calculate very large projects.

The Raytracer module is still a 32-bit program and therefore has to observe the 2GB RAM threshold.



Processor (CPU)

Minimum required: Dual core Intel or AMD processor with at least 2GHz clock frequency.

Optimum: Intel or AMD processors with 4 or more cores. For example, the AMD Phenom series or Intel Core i7 series.

Currently only standard Radiosity lighting calculations are multi-core and Hyperthreading capable.
