Dell e6540 (Amd 8790m Problem )

Hello My Laptop IS Dell latitude E6540 i7 4800MQ with intelhd-4600 and amd8790 M 

I Have few questions I'd ask

1.In Picture it is only intelhd-4600 is shown and there is no sign for amd8790m Card 

2.  In some laptops I saw display 1 and display 2 in DirectX,, which is not the case for me , Is it normal or there is something wrong ?

3. games are Slow , For example Pro evolution soccer 2019 can't detect amd radeon 8790m card , and it's slow on 1280*720 and 30 FPS 

Notes : 
A. i have updated the Bios and all drivers

B. I have all programs installed 

C. I have amd8790 Driver  (whql-win8.1-64bit-radeon-software-crimson-relive-17.4.4-may3) installed and i have tried all version starting 2013 to 2022 

D. I have switched games to run on amd8790 and still lag

thanks
