Yesterday I bought this brand new Lenovo laptop with and Intel i5-7200U and AMD R7 M360 on board. Tried to run Minecraft (Java version), but the F3 info only shows the integrated Intel GPU and the game was laggy. I'm sure that the power setting was set to 'Best Performance' and the laptop is connected to the power cable. Rebooting doesn't seem to work either. Could anyone identify what the problem is?
