Tested and improved Vista compatibility.The Quake 4 installer may require you to install Flash Player first, and Vista may pop occasional warning windows but in the end you will get a working installation. The install CDs (and DVDs) for Doom 3 and Quake 4 will install the game fine under Vista.If no OpenGL ICD is present, the default OpenGL driver is a wrapper to D3D provided by Microsoft, which lacks the necessary features to run id games with their full performance and graphical impact.Both NVidia and AMD/ATI have released an OpenGL ICD in their latest driver line. We've tested Doom 3 and Quake 4 to run fine on Windows Vista, provided you have an OpenGL ICD installed (provided by your GPU vendor).
