I was using win8 and on win8 I was able to play many games with good frame rates. Recently I updated to win 8.1 and installed drivers as instructed b dell but now I am unable to play games with 7670m (very low frame rates) where as I can play same games with intel 4000hd.
I installed intel 4000hd driver from here.
I installed 7670m driver from here.
Now my 7670m is useless intel 4000 can generate more frames then 7670m. I've tried installing new windows and drivers 2 times but still same problem. Please help me get around this I really want to keep win8.1, but if my graphics problem not solved I will have to go back on win8. thanks
