I have HP ProBook 450 g3 with Intel HD Graphics 520 and AMD Radeon R7 M340 graphic cards.
I tried to play The Witcher 3 and discovered that switching graphics is not working at all, no matter what I do.
I have downloaded latest drivers for my Intel & AMD cards, set max performance in Crimson everywhere I could (app itself, different setups etc.), launch the game and have 5-9 fps...AMD System Monitor shows that AMD card is just resting with 0% of usage all the time!
I tried with different drivers, even installed leshcatlabs drivers, set everything and it still doesn't work. It seems like I can't use my dedicated graphic card at all.
Do you have any ideas? I have paid for this card and now it's useless...
