Hi, I have a Lenovo G51-35 laptop with two graphics cards: R4 (main) and R5 M330 (discrete). When I'm trying to play GTA V (I suppose this problem is also in other games) only the first graphic card is used. I know that because when I'm trying to change settings (In GTA V), there is 1024MB, and my second better card (R5) has a 2GB memory.
I tried to set global settings (In Preferences/Radeon Additional Settings) to 'high performance' but this didn't work.
I have the latest drivers (I tried to reinstall and install older ones etc :/) , Windows 10.
