The dumb things people say, no matter what video card it will look the same the video card just processes the image does not upgrade it, only your screen control the quality of a image.
But for your question its not an engine problem its a power problem your computer is setup to use the best option based on power requirements so if the program does not use more processing power than the intel built in it wont switch to nvidia card, but there are ways around this but each way around is made by MFG of computer for example on my asus there is a piece of software that lets me disable the Intel built in and run everything on the nvida card.
TLDR switching wont make a difference at "looks", but if you want to run on nvidia anyway you have to read up the manual for your computer to figure out were the MFG put the option to disable built in Intel GPU, some computers is only in bios and other as software in windows.
I know this , owning my laptop for over 10 years now and hardly having no problems at all.
BIOS switching not available.
Power consumption to graphic demands.
NVidia config tuned for this game's exe to use NVidia chip.
Won't budge , still using Intel. Still a bit grainy.
And yes , it's an Asus too. N53JN
Anyone else got any idea?
