Little fps despite good gaming laptop?

Hello for a long time I have in almost all play much less fps pubg, wot, fortnite etc. Although I have a good laptop, namely the acer Aspire vx15, this has a 1050ti 8gb ram and intel i7 for fortnite should be loose, but I do not even come with low settings on 60fps, in wot me a high grafikeinstelung is recommended, but if I use this I have so around the 40 fps of the graphics card drivers is synonymous on the latest state, what could that be?

So with me it worked best to install razer cortex. Had a huge fps push

Is the graphics card used? Check it out in the Nvidia Control Panel, and otherwise select the game by right-clicking and there in the context menu your graphics unit. Do not have a laptop and therefore can't describe it more accurately.
