3D Analyzer is a program to anayze and test the efficiency of your 3D card, and improve it noticeably for 3D gaming.
For this it allows you to change the distinct characteristics of your card, and test its efficiency (DirectX merits special attention). With it you can optimize efficiency, above all if your CPU will permit, although still with a low range card. This program supports Direct3D as much as OpenGL, whichever it may be to optimize your system. For this you only have to select where to find the execute command for the chosen game.
