After a slow start for the original Fortnite, Epic made some changes and added a free battle royale mode, turning a struggling game into an overnight sensation. There's clearly a fine line between homage and copying, but while there are many similarities to PlayerUnknown's Battlegrounds, Fortnite takes a decidedly sillier approach to the battle royale genre. Key to this is a willingness to experiment, with limited time game modes, holiday events, and more—not to mention plenty of aesthetic customizations that can be earned/purchased.

Battle Royale mode is technically still in Early Access, but with a player base of over 20 million—and as already noted, it's free to try—we felt it was worth checking out how performance is shaping up. Given the somewhat cartoony graphics, you might expect performance to be a non-issue, but that's not entirely true. At the lowest settings, Fortnite can run on just about any PC built in the past five years. Officially, the minimum requirements for Fortnite are an Intel HD 4000 or better GPU and a 2.4GHz Core i3. The recommended hardware is quite a bit higher: GTX 660 or HD 7870, with a 2.8GHz or better Core i5. But what does that mean?
