The Far Cry series has indeed come a long way from being Crytek's baby back in the late 2000s. After making a name for itself as one of the most graphically demanding games on the market, Ubisoft has focused less on melting away user's PCs. This is also true for Far Cry 6, which has relatively modest requirements for those who want to play the game on the PC.
What do you need to run Far Cry 6 on PC?
According to Ubisoft, you could technically run Far Cry 6 on a $500 gaming PC. Sure, you'll have to make some heavy compromises in terms of frame rates and resolution, but the point remains.
Even better is if you could spend your money on lower-priced graphics cards like the AMD Radeon RX 460 and Nvidia GeForce GTX 960. Neither of these should cost you more than $100 on the second-hand market. If you have either installed and at least 8GB of RAM, your PC should run Far Cry 6 on low settings at a 1080p resolution with no problems.
