i been trying help my friend with this problem her laptop, a lenovo IdeaPad Z580,
this is the item from newegg

the issue is that when through the nvidia controls having it start games with the integrated HD4000 graphics the game she plays runs 60FPS and the 635M shows as inactive, in HWmonitor it will completely disappear and such, and then starting a game on the dedicated 1GB 635M the game will run down to about 40FPS, i check through afterburner and it said the gpu was running at proper speed about 667mhz, tho its running worse then the HD4000 what seems unreasonable, and it seems such a waste to have a dedicated card and never even use it
does anyone know how to fix this issue , any help would be much appreciated
