Reduce the graphic details. The CPU is slow and graphics is slower, you're not going to game on it.
I don't think the solution suggested by you is in sync with the configuration.
Dedicated Graphics Card - 1GB
External Graphics Card - 2GB
Processor Speed: 2.2 GHz
These figures speak itself.
You can have a petabyte of RAM and VRAM but it's not going to make the graphics card any faster, and 2.2ghz in 2016 is not really anything which can be called fast.
