If after reading the guide listed above not solve your problem, what is causing this is the profile system your system uses. Lenovo should have supplied a OEM profiles that install with your UMA, if not create your own profile for the game through additional settings / listed under-/ Preferances.
My Asus notebook just got a Crimson Update, I'm 1 step behind your hardware, but I'm taking a wild guess you have additional settings included with your version.
You didn't list which Software Version you have or/ using, so another wild guess.... 16.60 with driver pack 16.40, is that about right?
Anyways any additional info like this could help solve the problem. TBH your notebook should have auto-ran any major titled game in default High Performance.
