I tried to use "switchable graphics" but i have not the option, and i have not "Advanced settings" too in the software. I trie to launch by finding it in "programs" in windows menu but what i've foud is nothing, i have no "Advanced settings" in my PC. THe prob is I can't play to my video games because my CPU is 100% every time but my GPU only 40/50%, so it makes my games crash every time. I wanted to force the game to run on my GPU instead of my CPU.
I have a RX Vega 64, with a I5 4460 as CPU, 8G memories, Asus H81+ Motherboard.
