You do have dual graphics on that system, but the drivers for both the Intel and the Nvidia card haven't been updated in years while Win 10 has been. I would strongly suggest going through the manufacturer's site, that would be Asus, to obtain updated drivers for that model. There almost have to be updated versions available for both.
Once that's squared away, the typical method to get TS3 to use the Nvidia card would be to use the Nvidia Control Panel to set up a profile for the game (that's TS3.exe for Patch 1.69, TS3w.exe with the "w" for 1.67), select "Use High Performance Card" (or something like that) where given a choice since you do have dual, and while there make sure vertical sync is set to "On" or "Adaptive" and Triple Buffering to "On" for the game's profile. To see which card is in use, there should be a pull-down menu option on the Control Panel that says something like Show or Monitor card usage. I'm not on Nvidia so I can't provide a screen shot, but this one does a great job of showing the setup:
