BnS not using dedicated graphics

[Kelvinator]

Recently, I plugged my laptop to my friend's monitor to play BnS and it worked fine. But when I got home and played, my game is choppy and has low fps, I realised the game is using the integrated Intel graphics instead of my dedicated Nvidia graphics. Now I had this issue when I ran this game for the very first time on this laptop but that was easily fixed by setting it to use "High performance graphics" in Nvidia settings. I checked Nvidia settings and it is still set to use High performance graphics, so I don't know what's going on. Any ideas?

 

EDIT: a friend told me to try 32-bit client, this seems to fix the issue short term but I don't want to be stuck playing the 32-bit client.
