| 此现象一般出现在支持DX11的AMD显卡运行在WIN7上  具体说应该是5xxx  到底是游戏BUG 还是驱动BUG就不知道了  6xxx的好像还没有人反映过 解决方法就是把游戏强制在DX9模式下运行!  副作用就是载入地图好像比DX11要久几秒钟(不知道是不是我个人心理作用)
 C:\User\Documents\My Games\DiRT3\hardwaresettings下的hardware_settings_config.xml(有些玩家可能盘符不一定是C)
 右键编辑它
 <?xml version="1.0" encoding="UTF-8" ?>
 <hardware_settings_config version="53" deviceId="0x68B8">
 <cpu>
 <threadStrategy parallelUpdateRender="true" workerMapFile="system/workerMap4Core.xml" forceFeedbackProcessor="3" dvdStorageProcessor="3" dataSetMonitorProcessor="1" renderProcessor="0" updateProcessor="2" fileStreamProcessor="3" />
 </cpu>

 </hardware_settings_config>
 找到红色的那行把后面的 false 改成 true 即可!  记得保存
 现在游戏就运行在DX9模式了! 花屏解决!  想知道是不是运行在DX9模式下看FRAPS的帧数就知道了 透明底的就是DX9 黑底的就是DX10  DX11
 还有玩家说撞树或者回放的时候花屏那是游戏特效好不好!
