• Minimum of Windows Vista
  • Minimum of 4GB of ram. Depending on what games you have installed sometimes OCTGN will use up to 1GB of ram.
  • Minimum of 40GB drive Depending on the game, probably 1-2 GB for game data. Some games require just a few hundred MB, it really depends. You really should have at least(after installing games) at least 75% of your disk space free(on your main hard drive and also if you have your game data on another drive, on that drive as well). That's more important than a specific amount of hard drive space.
