I think my laptop uses integrated graphics instead of GPU

Yesterday I installed a Windows update, and this morning I played Catan online (a web game), and the animation was really buggy and everything was so slow. This isn't something new, my laptop used to freeze for a few seconds every once in a few minutes, but it went away after some time.

Anyways, I uninstalled the update using CMD (apparently Windows hides this option) but it's as buggy as before. I think this image explains the situation better: Imgur: The magic of the Internet. My graphics driver is up to date, my laptop is plugged in. I did see that the GPU 1 utilization percentage reached a few percentages.

Thanks :)
