I just translated it. So, there is a lot of complaints of gma950's10% more performance lose on Vista comparing with XP, despite that Vista drains system resource significantly, another cause is Intel's shitty WDDM driver. The idea comes from Intel's support page: http://support.intel.com/support/graphics/sb/CS-023606.htm Q3: Is Intel providing WDDM drivers for Intel Graphics Media Accelerator 900 (Intel GMA 900) on Intel 915 Express chipset-based platforms? A3: Intel will provide support for WDDM drivers beginning with the Intel® 945 Express chipset family and beyond. See question 5 below for a detailed explanation of WDDM support on Intel® 915 Express chipset-based platforms. However, Windows Vista is supported on the Intel® 865G, 915G Express desktop chipsets and 852/855GM mobile chipsets running XPDM (XP Display Driver Model) driver included on the Windows Vista install media. Windows Vista will install on these platforms, but advanced features such as Windows Aero will not be enabled as XPDM drivers do not support Windows AERO. Using old platform drivers (XPDM), Users would gain back 99% performance on Vista (However you can not enable aero or support newer games in trade). Here are some test reults: 3dmark01 On XP: 5268 Vista drivers: 4400 XP drivers on Vista:5175 (almost the same as on XP) Warcraft3 menu: Vista drivers: 47 fps Xp drivers: 60 fps dota: Vista drivers: 34 fps Xp drivers: 47 fps See the diffrence. And my idea is, may Angelic, Mad or other capable modders implement/ plant some codes in XPDM to WDDM to give more performence in Vista/7? swt -- INTEL 9xx SOLDIERS SANS FRONTIERS
