d3d12.dll is a required file of DirectX so if it’s missing then your DirectX components won’t work properly and give you issues such as this one.


Hope this provides a better understanding.“ Missing d3d12.dll error” appears on the screen when the d3d12.dll is corrupted or missing from your windows files, or your graphics card does not support DirectX 12. In this instance your can lower your DX mode, but at the cost of image quality - what most refer to as eye candy. This is where you take a performance hit via frame rates. The problem comes in when trying to game with mid to low level systems/video cards. Yes, DX11 can task a system, but if the system is relatively new and upper mid level, this shouldn't be a problem. This is the reason for DX11, and the move towards DX12. In other words today's systems are much more powerful and capable of handling more advanced multimedia (including games), and therefore require a more advanced DirectX API (Application Programming Interface). With today's systems being much more advanced than their predecessors were when DX9 was released there is somewhat of a "leveling" effect going on here. Same with system - a higher end system will perform better than a low to mid level system. Example higher end video cards tends to handle DX11 games more easily then mid to low end video cards. This is where system build/components comes into play. Your DX modes also depends on not only the game, but the video card and OS - see step 6 of my guide here: Tips on Troubleshooting Game Issues.Īlso, the higher the DX mode, the harder your system is tasked due to the increased textures (higher resolution) of the game, and this can have a huge impact on frame rates. DirectX is about improving multimedia to include games, videos, and audio - DirectX 11
