VariCAD - CAD system requirements


Support of OpenGL is always required. Hardware accelerated OpenGL is always recommended.

Windows version

The minimal required configuration:

  • at least 2GHz processor
  • 2 - 4GB RAM
  • HDD 250GB
  • Graphic card with hardware support of OpenGL graphics
  • Two-button mouse with the scroll wheel
  • Microsoft Windows Vista, Windows 7 or Windows 8

Linux version

The minimal required configuration:

  • OpenGL libraries
  • XServer supporting OpenGL (extension GLX)
  • 2 - 4 GB RAM
  • HDD 250GB
  • Two-button mouse with the scroll wheel
  • Graphic card with hardware support of OpenGL graphics

We recommend to prefer 64-bit operating systems over 32-bit operating systems. For 64-bit operating systems, it is better to use more RAM than for 32-bit systems.

According to results of extensive tests, VariCAD is rather less demanding than comparable competitive products. VariCAD can run on less powerful hardware. On the other side, VariCAD can efficiently exploit multiple core processors, hardware accelerated OpenGL, more system RAM or more VRAM (RAM on graphic cards), and for large assemblies, advantages of SSD. If 5-button mouse is used, additional two buttons are supported, too.

Hardware and software recommendations for large assemblies (aprox. thousands of parts):

  • Multi-core processor (Intel)
  • 8 - 16GB RAM, for extremely large data more
  • HDD (or, preferably SSD), 500GB
  • Graphic card with hardware support of OpenGL graphics (NVIDIA graphics chip, 1 - 2GB RAM)
  • Two-button mouse with the scroll wheel
  • 64-bit operating systems: Microsoft Windows 7, Windows 8 or Linux

Adding more RAM to your system enhances VariCAD performance significantly.
