Windows 8 Graphics: Microsoft Has Hardware-Accelerated Everything

[wraggster]

Microsoft has detailed the extensive changes made to the Windows 8 graphics subsystem (http://blogs.msdn.com/b/b8/archive/2012/07/23/hardware-accelerating-everything-windows-8-graphics.aspx) and DirectX 11.1. In short,everything in Windows 8 is hardware accelerated (http://www.extremetech.com/computing/133318-windows-8-graphics-microsoft-has-hardware-accelerated-all-the-things), and as a result its text, 2D, and 3D performance will blow Windows 7 away. DirectX 11.1 has also received a significant overhaul that should result in faster and more efficient games and applications. The bulk of the graphics changes in Windows 8 pertain to hardware acceleration for simple, typographically-rich Metro-style apps. In Windows 8, the rendering speed of text and simple shapes has been massively increased across the board: Title and heading text renders 336% faster than Windows 7; Lines render 184% faster; Rectangles render 438% faster; and so on. The rendering of JPEG, PNG, and GIF image files has also been improved in Windows 8, mostly by expanding SIMD usage. In one demo, Windows 8 decodes and renders 64 JPEGs in 4.38 seconds, while Windows 7 performs the same task in 7.28 seconds. Amongst a few changes to DirectX, the most significant feature in DX 11.1 is the new, simplified, unified Direct3D 11.1 API, which finally brings together the many API offshoots that MS has implemented in recent years."
