How Nvidia A100 Runs UE5

Not sure it has dx 11 compatibity.

Its an ai compute card not a consumer graphics card.
Maybe try running unreal with Vulkan. You can change the RHI in the ini files.

In the config folder find DefaultEngine.ini

find

[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_DX11

and swap it with

[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_Vulkan
