Need help with a technical issue!

Hey all!

I recently moved to college and I brought my desktop with me. After a arduous day, I wanted to come home and play some Total War Warhammer, but when I loaded up, for some reason everything was really slow. Then, I checked the graphics settings, and for some reason it was using the integrated graphics of my desktop instead of my graphics card!

I'm not sure what caused this problem. I updated my drivers, uninstalled and reinstalled the game, and I still have this issue. When I check on the Windows device manager, it says that my graphics card (GTX 1050) is working fine. What caused this issue and how can I fix it!

Thanks!
