If the dxdiag is limiting you, I will search someone to helps us with that.
I the copy files that you told me, from my brother PC , no results sadly.
So I think something more radical, I uninstall SimCity from my PC and my brothers PC, I download again from my brothers PC SimCity and choose the install in a external hard drive, I execute the game a check that is running with out issues. Then go back to my PC and execute SimCity from my external hard drive. No results
then do the opposite download SimCity from my PC and install in my external hard drive, then go to my brother PC and execute the game from there, the game launches with out issues again. I return to my PC and executed the game from the external drive, crash launches as always.
note. Both of has the same origin account, that is mine. both run same windows 10 version .
