Apps end up being implicitly targeted for performance at a certain level of computer. If your computer is faster than that level (which it seems it is), you won't face any problems. if your computer is slower, you will face problems.

But the kicker is, if everyone buys faster computers, the developers will correspondingly stuff more "features" in there to make it slower so the same number of people are still screwed. This is the recorded history of software engineering.
