The main issue on Windows 11 (and modern Windows 10) is that the game is hardcoded to look for DirectX 10, while modern systems default to DirectX 11/12, causing black screens or crashes on startup.
Unlike other older games, do use DXVK (Vulkan wrapper) for MGSV. It causes memory leaks on Win11 24H2. Stick to native DX11.
