AMD Radeon standalone graphics card not in use

E6440 with Radeon 8690M

Whether I install the Radeon or uninstall it, performance in games is the same. If I uninstall the Intel HD 4600, it drops to 1fps so clearly its using the Intel HD graphics and ONLY the intel HD graphics. Its like the Radeon didnt exist at all.

And performance in games is not good enough, theres visible lag

They said in another forum about another laptop that only the Intel HD graphics card is connected to the display so it cant be disabled. Is this true for Latitude E6440? if so, why does the Radeon make no difference in performance at all?

What is the 7-character "service tag/serial" number on your Dell Latitude E6440 laptop?

HERE is the on-line owner's manual for it.
