Windows 10: Fortnite now has beta DirectX 12 (DX12) support

Brink · Nov 26, 2019

On Monday, Epic Games announced that DirectX 12 support is coming to Fortnite. And today, the wait is over: anyone updating to the v11.20 patch has the option to try out Fortnite’s beta DX12 path!

What does this all mean? Let’s see if we can help!

What’s wrong with DX11?

Nothing!

We at the DirectX team designed DirectX 11 to be the best API for game developers to use in their engines. Even though we shipped DX11 a decade ago, for many games it’s still a great option. Having said that, DX12 has several advantages over DX11.

A major difference between the two APIs is that DX12 is more low-level than DX11, meaning that DX12 gives developers more fine-grained control of how their game interacts with your CPU and GPU. This is a double-edged sword: DX12 comes with fewer guardrails but gives developers more power and flexibility. With DX12, developers have even more options to optimize their games.

Additionally, DX12 is a modern API with more next-gen features than DX11, or any other graphics API. DX12 is the only API with broad native support for exciting new graphics features like Variable Rate Shading, DirectX Raytracing and DirectML.

What about Fortnite? Will switching to DX12 improve my performance?

While DX12 may improve overall average frame rate, the most important benefit is that DX12 can provide is a performance boost when Fortnite gamers need it most. During a heated battle, the number of objects on the screen can skyrocket, which places additional demand on the CPU*. This additional demand on the CPU can cause the frame rate to drop during the most critical moments of the game. Because DX12 uses the CPU more efficiently, the frame rate will drop much less when the game demands the most performance, providing a more consistent frame rate throughout the entire gaming experience.

To show this, we used PresentMon to collect some early performance data. Because competitive gamers care most about maximizing frame rate and minimizing latency, we lowered the graphics settings, but set view distance to “Far”. Your specific results will vary depending on your exact machine configuration.

While the average frame rates for DX12 were slightly higher than DX11 (2%), DX12 was much faster when it matters most. When the game is rendering the most demanding frames (slowest .1% of frames), DX12 shows an ~10% average improvement in frame rate.

Am I CPU-bound?

The truth is, it’s complicated and depends on your machine, settings and playstyle.

In general:

Machines with modern GPUs will tend to be more CPU-bound.

Machines are CPU-bound at lowered settings. (Many gamers tune down their graphics settings to max out performance to get a competitive advantage in the game. If that’s you, you’re likely CPU-bound for parts of your gameplay).

Machines tend to become more CPU-bound when there is lots of action happening.

How do I try out DX12?

To try out DX12 in Fortnite, go to your Settings menu in Fortnite and make sure you’re looking at your Video settings. At the very bottom of the menu, select DirectX 12 (BETA) next to DirectX Version

Will my machine be able to run DX12?

Anyone who meets minimum specifications for Fortnite can run DX12. If you’re on Windows 10, you’ll be able to test out DX12!

Fortnite not Running With DX12

I have a problem. My Fortnite is not running. When I run it, it tells me that it fails to find hardware with DX11. But when I checked DirectX Diagnostic Tool, it showed I had DX12. How can I run Fortnite?

Fortnite not Running With DX12

Fortnite, as is shown by the error, is not a DX12 game. Fortnite uses DX11, and Win10 comes with all versions of DX, not just DX12.

Did you download and install the game from the EPIC store or somewhere else ?

btw - To determine if your graphics processor can use DX12 you need to click on the
Display tab in dxdiag and look at the

Feature Levels in the right hand column.

You can verify if all DirectX files are installed by running the DirectX Web Installer...

Download DirectX End-User Runtime Web Installer from Official Microsoft Download Center
