With its latest GeForce 384 series graphics drivers, NVIDIA quietly added DirectX 12 API support for GPUs based on its "Fermi" architecture, as discovered by keen-eyed users on the Guru3D Forums
. These include the GeForce 400-series and 500-series graphics cards. The support appears to be sufficient to run today's Direct3D feature-level 12_0 games or applications, and completes WDDM 2.2 compliance for GeForce "Fermi" graphics cards on Windows 10 Creators Update (version 1703), which could be NVIDIA's motivation for extending DirectX 12 support to these 5+ year old chips. Whether they meet your games' minimum system requirements is an entirely different matter.
