Question Intel graphics card vs. nvidia graphics card in Dell XPS 15 9550

Oct 23, 2019
  • Intel (R) HD Graphics 530
  • NVIDIA GeForce GTX 960M
So I'm a massive noob when it comes to this stuff. Long story short, I have a feeling that while I'm playing games my laptop swaps graphics card - possibly due to overheating. e.g. I'll be playing fortnite on around 100fps+ and every now and then it'll have a sharp drop in performance that often lasts a couple of minutes (down to about 30-40fps). I'm just wondering if and how I prioritise the nvidia card at all times and if this would even help? I'm looking into cooling pads as a potential fix but I'm really just not sure what to do. e.g. what apps to use to test these things, what to disable and enable etc. Please help.
