Radeon Additional Settings Unavailable & Game Lag

Hi,

Im using Lenovo Ideapad 500 AMD A10 6th Gen. 8Gb Ram DDR3

It has AMD M430 and R6 Graphics.

In 17.2.2 version, I can't see the additional settings in Preferences.

Also When I play games like Call of duty MW3, World at war and Sniper Elite 2, the fps is too low..20-25fps even in low settings.

I saw youtube videos playing these games with same specs at high settings.

Can you please help me out what's wrong with the settings??
