Doom Eternal arrives to rip and tear in only a couple weeks, and now we know what kind of rig you’re going to need if you want on PC. The requirements are surprisingly beefy considering this is a game that’s going to be running at 60fps on consoles, and is even getting a Nintendo Switch version, but I guess id Software is really looking to push things on PC. Minimum requirements include a GTX 1060 or equivalent, and the Recommended 1440p/60fps setup is an Intel Core i7-6700 or AMD Ryzen 7 1800X and a GTX 1080 (8GB) or AMD Radeon RX Vega 56 (8GB). Not too crazy on the upper end, but the minimum bar to entry is definitely high. You’ll also need to clear 50GB of disc space to play the game.
