I have asked that in many different forums but also wanted to ask here.
my MSI GT60 0NC started to give really low fps in games that I had been playing very smoothly before. It was ok a few of hours ago. It just doesn't switch to the GTX670m. It uses the crappy HD 4000 and it drives me crazy. Also I didn't change any settings. I selected "use high performance nvidia processor" option from the control panel. My drivers are up to date. Any suggestions?
