Tested environments are:
  • Windows 7 and Windows 10
  • Macintosh OS X 10.8 or newer
  • Linux 4.0.x or newer

Any PC build in the last 8-10 years should suffice.

About 400 MB free memory and up to 200 MB of disk space are needed.
Naturally a faster CPU, more cores and more RAM never hurts (especially for 4 ply evaluation) ;-)

A resolution of 1280x800 or more is recommended.
