I am playing GTA 5 on a 7670m with some settings on high and others on normal with 16 antistropic filtering and FXAA and V sync on . I play it on full resolution and am able to get 40+ fps.
I am also having the same problem but with only a few games like Ride 15 and Tomb Raider 13 . I can`t select my dedicated gpu 7670m 1GB GDDR5 .When I start Ride it only shows Intel hd 4000 in device description. Please someone help.
I have the same gpu as yours and I was able to play at high setting these games
