Do you play equally demanding games without these issues?
This could be as simple as a software configuration, such as a driver issue or the game not installing properly.
If you play games of equal graphics/strain and they play well, then it's not a problem with your laptop, it's a problem with software.
Do games of the same graphics/strain cause these same issues? If that's the case, either:
1. Your laptop isn't powerful enough to play (even though it says recommended)
2. A part(s) of your hardware are malfunctioning. Which part can be determined by doing a few tests, but I won't touch on those until I know if this is the case.
If I were you, I'd just start making sure my graphics drivers were updated, reinstall the game to make sure it wasn't an installation issue, etc.
