dolphin just doesn't recognize dedicated GPU

[Niewidomy]

First of all try to disable the power saving. Control Panel > Power Management > Balanced > Change plan settings > Change advanced power settings > change ballanced to high performace. You could also find there your GPU settings if they are there crank them up too. (notice your battery life will be much shorter).
You might also want to check if there is no option in the bios to make your dedicated GPU be used as main.
