Question Why does my laptop working worse with my dedicated graphics card than the integrated?

[hovl]

I have a Acer Nitro 5 laptop with an Intel UHD Graphics 620 and with a MX-150. I have the newest driver from Nvidia Geforce Experience and when i set the MX-150 at the Controll Panel the games acting weird and the overall performance is weaker. I really dont know how but it cause a lot longer loading screens too. What did i do wrong? How can i fix that? Bc I can't believe that the MX-150 is weaker than the integrated intel....

Welcome to the forums, newcomer!

You might want to see if your laptop is pending any BIOS updates. Following that check and see if your OS os pending any updates. If your OS and BIOS are up to date, use DDU to uninstall your GPU drivers(all of them) then manually reinstall your Nvidia based GPU's driver in an elevate command, i.e, right click installer>Run as Administrator, after sourcing your driver from Nvidia's support site.
