Hello, I'm new to here.

I bought a Mantiz Venus and try to use it in bootcamp with internal display. After dozens of times black screen and recovery, it finally recongize both 560X and 5700XT.

So, here is the question. Did I succeed?

In after burners,I can see some of the games are using 5700xt for better performance, like: World of Warcraft, Origin sin 2. But the Witcher 3 still won't use 5700xt unless I plug to an external display and close my laptop. Also the game performance didn't meet my expaction at all.

Anyone get a similar problem?

by the way,  I'm using:

2019 15" macbook pro i9 9880h with 560X

Mantiz Venus with Sapphire 5700 XT Nitro+ 

WTG Windows 10 latest version 1909 on a ssd.

Access the Switchable Graphics menu in AMD Radeon settings to assign W3 to your 5700XT

It worked out! Thx! 😀 

But in Adrenalin 2020, AMD removes this setting. In Win10, it can be done in: Display setting -- Graphic setting -- add the app and choose high performance(it should be named as your external graphic).
