Is there in any way to make apex run better

Apex says on its main page that it uses 6GB of ram, and I only have 4GB of ram. I'm searching for a way to make the gameplay any better or even playable at least because my average fps is about 6 fps. I have tried things like Razer Cortex and such, but none of them worked good enough for this game.

 I need help. I use Intel Core I3. It's also good if any of the ideas given doesn't require any sort of payment.

 Thank you if you reply this.
