Just installed this game and by default this game runs on my Integrated Graphics and not the High-Performance NVIDIA Processor. Running using the Integrated Graphics, the game main menu was lagging like it was around 5-10 fps. Scrolling the options was so slow and quite annoying. However the gameplay was smooth, only at the main menu was lagging.

Running the game using High-Performance NVIDIA Processor settings, all were smooth, both main menu and gameplay. However I cannot choose to run this game using the High-Performance NVIDIA Processor by default, I don't know why.

Is there any way to force this game to run using the High-Performance NVIDIA Processor ?

I already go to NVIDIA Control Panel and set the game to run using High-Performance NVIDIA Processor. But when I ran the game it still use the Integrated Graphics.
