Integrated GPU performs better than Dedicated GPU? :/

Hi, I have recently purchased a dell LATITUDE e6430 i5 3340m 2.7 ghz + intel hd 4000+ nvdia nvs 5200m (dedicated) + 8gb ram for around 300 euros (second hand).
After a few tests, i noticed that the dedicated gpu performs a lot worse than the integrated gpu, for example on fortnite on the lowest settings with the intel hd gpu, the fps will fluctuate between 25-45 fps (which seems quite fluid on this game) however with the nvidia GPU the fps is at 10-15 fps.
I don't really understand this so any help is much appreciated.
Ps: I don't have enough money to buy myself a brand new gaming laptop and I can't send the laptop back to the seller as the guarantee doesn't include functional products :(

That Nvidia graphics is Fermi based, that's older than the Intel HD 4000. Not only that, but it was a budget graphics solution even back when it was new. So that's why performance isn't that good.

It's kind of important to research these components BEFORE you buy. That way you know what you're getting. Don't assume, for example, that a laptop has upgraded graphics just because it includes an Nvidia or AMD dedicated GPU.

Also, be reasonable in expectations. Laptops aren't great for gaming, not counting special gaming laptops, and this one is from 2012. You want to play Fortnite on a business oriented laptop from 2012? That's asking a lot.
