Yesterday I upgraded my Lenovo ideapad U410 from Windows 7 to Windows8. The laptop is equipped with a 610M and Intel HD graphics 4000. On Windows 7 I could run World of Tanks at 25-30 fps reliably but now it is down to 5-15 and pretty much unplayable. I have also tried Kerbal space program but it has not suffered as much. I have done all I can to try and figure out the cause of the fps drop. I need some help.

The Nvidia software acknowledges that there is GPU activity but the performance isn't what it used to be.

Or is it that I may be looking in the wrong place?

Most likely, the drivers for your graphics chip aren't optimized for Windows 8. Make sure that they are updated.

WoT is an awesome game, whats your best vehicle?

I've installed Nvidia experience and used it update the drivers for the 610M and used windows to search for a driver for the intel card. as far as I can tell they are both up-to-date. My highest tier tank is the Tiger II, I really like the German stuff
