Far Cry: New Dawn has received its official, dev-provided PC system requirements, and the short of it is that if your rig could run Far Cry 5, you're definitely going to be running New Dawn as well. There is a bit more nuance to it than just that, however.
Far Cry New Dawn system requirements were always going to be similar to those of Far Cry 5 since the game is running on a slightly upgraded variant of the engine its predecessor was running on. Ubisoft is touting great optimisation and a wide variety of settings to toy around with, too.
Interestingly, instead of simply providing minimum and recommended system requirements (as one usually does), Ubisoft have gone into much more detail for Far Cry: New Dawn's hardware specificities with dedicated 4K configurations to consider as well.
