For the engine itself to function, the following software baseline is required:

Next came the graphics stack. DirectX 11 and 12 runtimes, the latest GPU drivers, and shader compilers were like fuel for the rendering pipeline. He updated his GPU driver, watching the installer crawl through device lists and finish with a reassuring green tick. Shaders were temperamental—one wrong compiler and his skybox would fracture into static—but with the x64 toolchain aligned, the risk of stack overflows and address-space conflicts fell away.
