![]() wddm 2 maps better to modern hardware, so if you have a wddm 2 driver, even older titles not using DirectX 12 should benefit. However that doesn't mean it supports DirectX 12. However "wddm 1.x" is sufficient to run Windows 10, hence you will see a lot of old hardware (DirectX feature level 10) still supporting Windows 10. ![]() You need the latter for using DirectX 12. Windows Vista introduced "wddm 1" and Windows 10 "wddm 2". The driver implements a low-level api designed by Microsoft called "wddm". Wikpedia has a nice overview on all NVIDIA chips and AMD/ATI chipsĪn application/game developer uses the DirectX runtime to talk with the GPU driver. For AMD It's Radeon HD 5xxx since late 2009. On Desktop PCs hardware supports various feature sets, Microsoft standardized some of those and called them "feature levels".ĭifferent hardware supports different feature levels, most people nowadays will be on 11_0 or higher, which can be seen at valve's hardware survey website.įor NVIDIA a DirectX 11_0 feature level class GPU is Fermi (GeForce GT 4xx) and above since early 2010. Seeing some misconceptions about DirectX hardware and software in the feature request thread, wanted to move the topic to a dedicated thread.
