Operating system	Microsoft Windows XP or later.
Computer and processor	Intel Core i7, i5, Core 2 Quad, Core 2 Duo or AMD Atlon64-X2 are recommended for faster calculations and better visualization
Memory	512 megabytes (MB) of RAM or greater. 2 Gb or more is recommended to work with photos
Hard disk	100 megabytes (MB) of available hard-disk space. If you plan to keep your projects with photographs longtime you may need large HD (100 -200 Gb or more)
Display	High-color Super VGA 1600 x 1200 x 24bit. 1920 x 1200 x 24bit or higher resolution monitor is recommended for convenient work
Video card	VGA card with OpenGL support NVIDIA GeForce 6600 or higher, ATI X1300 or higher are required to enable HDR rendering* (see section HDR photorealistic diamond and inclusions visualization). We recommend to use at least NVIDIA GeForce 6800, ATI X1600
Other	Logitech MX Revolution mouse is recommended

CPU performance comparison

*The HDR photorealistic diamond and inclusions visualization requires Graphics hardware supporting specific features. Please test your GPU (Graphics hardware) with DiamCalc – Graphics Compatibility Evaluator utility. This utility will attempt to render a reference data set in order to check if your Graphics hardware is compatible with new OctoNus HDR rendering engine. Even if you get negative test result the non-HDR visualization will be available in the program. Most of existing Windows computers is compatible with non-HDR OctoNus rendering engine. For optimal performance of Automatic Cavity Allocation we recommend to use: MZ16 System with 1.0x objective: 110x magnification Z16 System with 2.0x objective: 80x magnification M205A System with 1.0x objective: 115x magnification
