With the Engine Operating System Ubuntu 22.04, Rocky Linux 8 Compiler clang 18.1.0 Optional IDE Visual Studio Code, Rider Software Installed by the Prerequisite InstallerThe Unreal Engine includes a prerequisite installer that installs everything needed to run the editor and engine, including several DirectX components and Visual C++ redistributables. When you install Unreal Engine through the Epic Games Launcher, the Launcher automatically installs these prerequisites for you. However, you may need to run the prerequisite installer yourself if you build Unreal Engine from source, or if you need to prepare a computer with all the Unreal Engine prerequisites for a specific purpose—for example, if you are setting up a fresh computer to act as a Swarm Agent.You can find the installer in the Engine/Extras/Redist/en-us folder under your Unreal Engine installation location.Support for 32-bit platforms has been removed in Unreal Engine 5.If you use Perforce to get the Unreal Engine source code, you'll also find precompiled binaries in the same Engine/Extras/Redist/en-us folder of the Perforce repository. The source for the installer is under Engine/Source/Programs/PrereqInstaller.The following table lists the software that is installed by the prerequisite installer. DirectX Components Visual C++ Redists XInput 1.3 (April 2007) Visual C++ 2010 CRT X3DAudio 1.7 (February 2010) Visual C++ 2010 OpenMP library XAudio 2.7 (June 2010) Visual C++ 2012 CRT D3D Compiler 4.3 (June 2010) Visual C++ 2013 CRT D3DCSX 4.3 (June 2010) Visual C++ 2015 CRT D3DX9 4.3 (June 2010) Microsoft Visual C++ 2015-2022 Redistributable D3DX10 4.3 (June 2010) D3DX11 4.3 (June 2010) The most important DirectX components from that list are the XInput, X3DAudio, and XAudio dependencies. These aren't included in standard installations of DirectX (and aren't distributed with Windows by default), so they have to be installed manually or distributed with the application.Graphics Card DriversWe currently recommend using the latest stable releases from each card manufacturer: Download NVIDIA drivers here Download AMD drivers here Download Intel drivers here Performance NotesThe spec below represents a typical system used at Epic (a Lenovo P620 Content Creation Workstation, standard version). This provides a reasonable guideline for developing games with Unreal Engine 5: Operating System: Windows 10 22H2 Power Supply: 1000W power supply unit RAM: 128GB DDR4-3200 Processor: AMD Ryzen Threadripper Pro 3975WX Processor - 128MB Cache, 3.5 GHz base / 4.2 GHz turbo, 32 Cores / 64 Threads, 280w TDP OS Drive 1 TB M.2 NVMe3 x4 PCI-e SSD DATA Drive 4 TB Raid Array
