I do use the NVIDIA card, more appropiately, NVIDIA GeForce GT 525M.
I disabled the NVIDIA GeForce GT 525M and things didn't seem too different, I don't believe there was a change at all.
When I disabled the Intel(R) HD Graphics Family, all hell broke loose. Screen turned black, had to restart, screen went to a much lower resolution.
Also for some reason images seem to be a much lower quality on the layout for Construct 2, but text seems to work just fine, very high quality.
EDIT: My computer is fine now, after re-reading, sounds like my computer went to poopooland, but it's fine. Also, I can't message you since my rep isn't over 500. ):
