PCSX2 uses the GSdx plugin for rendering. If the DirectX End-User Runtime files (specifically D3D11 or D3D12 files) are missing or corrupted, PCSX2 will fail to initialize the graphics plugin. This results in the emulator crashing upon booting a game or failing to open entirely. update directx libraries pcsx2

Before diving into the "how," it is essential to understand the "why." Emulation is a resource-intensive process that demands near-perfect synchronization between the software and hardware. Unlike native PC games, which are built to run on a variety of systems, emulators are trying to mimic a closed-console environment. This results in the emulator crashing upon booting
This is the modern standard, designed for newer architectures (Nvidia Maxwell and newer, AMD GCN and newer). D3D12 allows for lower-level access to hardware, potentially offering better performance. However, it is stricter. If your Windows OS does not have the specific D3D12 runtime libraries updated, PCSX2 will simply fail to switch to this renderer.
