So the question is why a project created in a language that has been around since before the devices being emulated are more mature than ones in a language that is 8 years old?

Sorry to be so snarky. It probably depends on people's time working on it and their familiarity with async processes. This is an inherent problem with any media like that. With sound, it's primarily that it can't come before the image but can lag behind the image. Stuff like this.

I don't think any programming language is going help with that because it's how we perceive things, not just how correct your code is.
