Windows – After increasing RAM size, Windows Experience graphics index rating went down

I've had a similar problem with my laptop and I've found a trick. My problem was that the original driver is very old and I wanted an updated driver. I've called the manufactor of my laptop but they refuse to update the driver. Any new driver from my graphic card didn't work because of this onboard and discrete switchable graphic card thing. I didn't care much about the switchable options but I didn't make it work. The trick is to use the old original installer and swap the graphic card driver with a recently updated driver. AMD graphic driver is only a tiny part of the huge package with CCC and so on. This works great.

AMD HD5450 is not a great card to use as upgrade for Intel HD3000.

But Windows Experience Index is a strange thing. I replaced HD4830 card with HD7770 overclocked edition which performs 2~3 times better in every aspect (and not to mention the all newest standards) and my index dropped from 7.3 to 7.1.

So don't bother with this... In Windows using higher resolutions you should "feel" better with HD5450.
