Have u done any research into the fix? Cause after some research i found out how to fix Grid 1 which loading screen crashes if u are using an 8 core processer by Intel, and graphics stuck at 720 by 1280 if u have a card over a GTX 660 ti which was what i was using before i installed the 980.
If u are interested here are the links:http://forums.overclockers.co.uk/sh
