As technology evolves, so does Fortnite!

The PC version of Fortnite currently requires a graphics card capable of running Microsoft DirectX 11. In v11.20, however, you’ll have the added option to play the PC version using Microsoft DirectX 12!

By using DX12, PC players with high-end GPUs may experience a higher and steadier frame rate. This is because DX12 delivers better CPU performance and allows for the distribution of rendering jobs across multiple cores.

In the future, we plan on adding features to Fortnite that are made possible by DX12. Allowing players to opt into DX12 before these features are added will give us valuable information in our development efforts and help us shake out any bugs. 

If you’re interested in helping us test DX12, please jump in and give the new option a spin. 

Thank you for your continued support!

UPDATE (February 21, 2020):
To address stability, the DirectX 12 beta has been disabled for Windows 10 versions 1607 and older.
