DirectX 9 was released in 2002 and worked with Windows 98 and XP. It introduced Shader Model 2.0 and Pixel Shader 2.0. DirectX 10 was a major upgrade to DirectX that was only available in the ill-fated Windows Vista. It was a significant upgrade though. DirectX 11 launched in 2008 and bought improved support for multi-threading so developers could make the most of multi-core CPUs. A version of it was also used on the Xbox One. DirectX 12 launched with Windows 10 in 2015. The most important update here was allowing for more efficient resource utilisation, the goal of which was to achieve “console-level efficiency on phone, tablet and PC”. It also worked nicely with multi-GPU systems including AMD CrossFireX or Nvidia SLI setups. DirectX Raytracing (DXR) was added to Windows 10 in 2018 and introduced real-time ray tracing. DirectX 12 Ultimate was announced in 2020 and is likely the most significant upgrade yet.
