The minimum and recommended specs for the PC version of Watch Dogs 2 are out there now. The good news is that the recommended specs aren't that intensive, so most folks who have a fairly recent computer will be in good shape. The bad news is you'll have to wait a couple weeks after the console version hits the market.
The dev team behind Watch Dogs 2 is taking that extra time to make a few enhancements to the PC version. Specifically:
