Crashing before ford gt screen (GEFORCE GTX 850M)

so i downloaded this the day it came out and it crashed immediately saying my driver was incompatible, which is fine. i figured new game, might be a few days/weeks. kept checking back now and then to see but still the same error (AP301). tried the page up thingy and it gets me to the ford gt load screen then crashes every time. from a google search it seems like other people with a GTX 850m can play it so why cant i? my driver is fully up to date and i have no problems with anything else??
