It is really easy to criticize something when you don't know the inner workings of it, much as each company or project, Dolphin has a set goal and the devs are going to prioritize what they think is best for the emulator right now. As for the "sour treatment" you speak of, don't expect to be treated like a child here, they don't mean to be sour, just some people are thick and they try to make a point, keep in mind Dolphin is a profit-free project and could easily just stop working if they wanted to. You can't just "buy" the "best build", not everything works with money, it's not that easy and sorry but if your pc is stuttering in games it's your pc's fault, if you think you can do a better job you're welcome to try, just don't criticize
The right man in the wrong place can make all the difference in the world.
