laptop not using dedicated gpu in gta 5

[QUBIE]

so my ASUS n550 jk is not not using my NVIDIA gtx 850 m video card when i run GTA V ...instead it's running the HD graphics 4600 video card....thus leading to low performance ...and when i try to disable it ...is still won't use it ...instead it is using a 512 mb video card ...any help on that ?

Have you switched to pcie graphics in bios?

It should switch itself.

My guess is that you have allocated 512mb ram to run the hd4600.
