Can I run Fortnite with a GeForce RTX 4090?

With 24 GB against the 12 GB Fortnite asks for at ultra, the GeForce RTX 4090 carries more than twice the video memory this game will ever want, and clears every tier it defines.

The GeForce RTX 4090 arrived 5 years after Fortnite shipped, so the game was never designed with it in mind: 13 of the 47 cards we track stop at the same point in Fortnite. It sits 2 of 47 on our index.

That readout is the best this card can do in Fortnite: it assumes nothing else in the machine holds it back. Your own processor and memory can only lower it, never raise it.

The same card with three different processors

In Fortnite the processor beside a GeForce RTX 4090 changes the answer, which is why a card-only verdict is not worth much here. Each row assumes 16 GB of system memory.
