Xtreme-G drivers are modded and tweaked versions of official nVIDIA and ATI display drivers aimed at harnessing optimal gaming performance from your GPU. This post is about the Xtreme-G 180.84 drivers which are based on nVIDIA ForceWare v180.84 released several days ago. I tested these with my Grand Theft Auto 4 installation and observed an 1-3 FPS increase over the official v180.84 drivers. Plus the overall quality of graphics looked better (sharper edges, etc) with the modded drivers.
Xtreme-G 180.84 drivers work with almost all Geforce 6,7,8,9 series and GTX 260/280 graphics hardware. Although most people will get a performance boost and better graphics quality with these drivers, keep in mind that Xtreme-G is not officially supported by nVIDIA.
