Why My windows experience index reduce after installing Newer driver??

Why My windows experience index reduce after installing Newer driver??

Hi Wen10,

Updating the graphics card drivers won’t always mean an increase in the Windows Experience Index. Sometimes there are cases wherein the newer or later drivers could cause a reduction in performance, especially when playing games. The Windows Experience Index is only a benchmark, giving you a clue as to which component of your system needs improvement.

A built in graphics card which uses shared system resources ranks as the lowest on the index. If you really want to find out if the newer drivers are superior and has given your system a definite improvement follow my simple tips.

1. Uninstall your current drivers and rollback to your previous one. Then run the Windows Experience Index. Did it return to its previous value? If it did, then you are better off using the older drivers. You just have to wait for a newer driver that gives you a higher index rating. There are also cases where the stock driver for your particular graphics chipset and your laptop or desktop manufacturer’s versions are different. The drivers have been internally tweaked to increase compatibility with the system it came with.

2. Use GPU Caps Viewer http://www.ozone3d.net/gpu_caps_viewer/, that can give you vital information on your graphics card capabilities as well as do a rendering benchmark. To test how many frames per second your graphics card is capable of, run the application GPUCapsViewer, select OpenGL 1.2 Simple Mesh on “OpenGL 2.x,3.x, and OpenCL Demos” (last item on the first tab “GPU/CPU”) and click on “Start”. You should see a rotating image shaped like a donut called a simple torus mesh. Take note of the “Current FPS”, as well as the “Min,Max, and Ave FPS” figures. Do the test using both the old graphics drivers and the new updated one. Mark your test results. Which one did have a higher FPS value? Use the driver that gives you a higher FPS value.

3. Run a particular game like Counterstrike Source, or Half Life, enable the console and enter “cl_showfps” without the quotes. Take note of the FPS numbers as you do the test using both old and new drivers. Compare it with the results using the GPU Caps Viewer. Did they both arrive at the same conclusion? Switch to the drivers that give you the highest FPS numbers.

4. It is a departure from the current stock drivers you use, but I have tried it and it increased my Windows Experience Index by several notches, plus the fact that my FPS numbers doubled. It not only optimizes your gaming experience, it also enhances your imaging, movie viewing, and overall desktop experience. There are other sites dedicated to driver nodding that can increase the performance of your graphics card chipset. Almost all brands have dedicated sites for that purpose. Look for them via Google search.

5. The infiltrations allow certain features to be enabled based on a particular Windows Experience Index number. Go to “Start”, type “run” without the quotes on the “Search programs and files” box. Enter “%windir%PerformanceWinSATDataStore” without the quotes and “enter”. You should be able to view .xml files now, just look for the latest file and open it with wordpad. Search for the line having “WinSPR” without the quotes and edit like the example below: WinSPR SystemScore 4.2 SystemScore MemoryScore 4 MemoryScore CpuScore 3.4 CpuScore> CPUSubAggScore 3.4 CPUSubAggScore VideoEncodeScore 3.4 VideoEncodeScore GraphicsScore 3.4 GraphicsScore GamingScore 3.4 GamingScore DiskScore 4.2 DiskScore Change the values to whatever number you wish them to be.

You’ll need to take ownership of the .xml file before making changes to it. Please remember that infiltration does not increase your system performance, it only allows certain features otherwise locked by a low Windows Experience Index.
