### Summary UEFN fails to launch on my system, showing the error: “A Feature Level 5 video card is required to run the editor. AvailableFeatureLevel = ES3\_1, ShaderPlatform = PCD3D\_ES31” I’m using an RTX 2080 SUPER with full support for DirectX 12 / Shader Model 6.6 / Feature Level 12\_1. All drivers and DirectX runtimes are current. ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing? Stability ### Steps to Reproduce 1. Launch UEFN from Epic Games Launcher 2. Observe crash or error: “A Feature Level 5 video card is required to run the editor. AvailableFeatureLevel = ES3\_1, ShaderPlatform = PCD3D\_ES31” ### Expected Result UEFN should launch normally using DirectX 12. ### Observed Result UEFN crashes before launch. This prevents use of the editor entirely. ### Platform(s) Windows 10 Pro (Build 19042) RTX 2080 SUPER (Driver 32.0.15.8088) DirectX 12, Feature Levels: 12\_1, 12\_0, 11\_1 (confirmed via dxdiag) WDDM 2.7 ---

I get this as well, but I’m using a legacy video card so there will be no more updates for it. Was about to face not being able to map for a while, but remembered use -d3d11 in the epic game launcher as a command line argument to force the editor to use DX11 mode It runs, keep us going until the next driver update or saving up for a new graphics card ---

Hello, Old integrated GPUs cannot run the editor in DX12. They used to automatically fall back to DX11, but unfortunately we broke this behavior when we introduced DX12 performance mode in the client. We will fix the problem ASAP, but in the mean time the solution is indeed to run with the -d3d11 command line argument, to force the editor to start in DX11. However, I’m not sure what’s wrong in Abu\_Daxi’s case. A 2080 on Windows 10 20H2 should be able to run DX12 SM6, but the engine says this: > DirectX Agility SDK runtime not found That means it cannot load D3D12Core.dll from INSTALL\_DIR\FortniteGame\Binaries\Win64\D3D12. Can you please make sure this DLL is present? ---

That makes sense, thanks for the info, so I’ve been running DX11 mode all along anyway he he ---

Thank you - this has worked for now! I’ve started looking into eGPUs - I hope this doesn’t cause an issue with the MSI RTX 2070 SUPER… Edit - I’m encountering a “Project validation failed” message after trying to test the map; I’ve validated files under the manage section. Is this a separate issue? ---

I have been having the same issue, I have Dx 12 and it worked before the most recent update. I am trying the launch option override now. I also noticed it says UEFN version 37.0 using Unreal Engine 5.7 which hasn’t even been officially announced yet and 5.6 just officially released. ![UEFN37](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/1/0/4106ca4802bd79b92946a79f8d752977bb43c296.png) [Next page](https://forums.unrealengine.com/t/uefn-crashes-on-launch-feature-level-5-not-detected-despite-rtx-2080-super/2633776.md?page=2)
