After installing the new windows 10 creater update,
graphic card software seems not to work properly with IV.
If however you installed the new version on windows 10
To run IV
Right click and hit properties, tick OVERRIDE HIGH dpi Scalling behavior. Then Apply and Ok And it should work

The new update claims to have better enhanced gaming experiance, I noticed a difference from 150fps to 170fps on IV (untouched original game)
