Firstly, when you increase the accuracy of emulation, there will generally always be a bit of a slow down depending on what was done. Secondly, even though you can run PC games just fine, that means nothing for Dolphin. Dolphin has always required strong per core performance (strong single core performance). I'm sorry your stuck with a Ultra low voltage Intel CPU, but that won't cut it on more intensive games (of course I'm pretty sure you can still run lighter games due to Haswell's excellent performance in dolphin all around).
Also, you say that the devs are throttling your performance just because? It's not like Intel Sponsors these people to advertise their products using such a niche piece of software (I may love dolphin, but it isn't a very well known program compared to other software).
Several Major Accuracy Improvements since 3.0 include:
Fixed AX ucode DSP HLE (it's a bit more intensive, but for anything using AX ucode, you no longer have to use the intense LLE to fix audio problems etc)
The beginnings of new Zelda ucode HLE code, so the same as above but for games such as SMG
Tons of little glitches and inaccuracies fixed everywhere (including the well know broken Heat affects in Wind Waker).
There are even more that I can't list, since I either can't remember them or simply was not aware of those fixes.
Dolphin has changed a lot since 3.0, and for some (including me) have received performance boosts from these changes. You can keep using 3.0 if you wish, but you won't receive support since it is so old.
Maybe if you don't believe me you should go into the Github page and look at all the changes they made in the past and all of the different branches that have been made to fix/improve certain things lol?
