So it's more than just the version which affected MK Wii.
Open AL sound caused massive audio problems, mainly massive skipping
Open GL backend worked better at full speed, Direct3D was choppy even at 100%
I found out, Intel Turbo Boost works every time Dolphin is playing, but not when it's open. This increases my CPU clock speed from 2.3 to a crazy 3.1, considering it's a laptop and Dolphin can overclock it. This gives me 100% speed now.
Compared to 4.0-1403, the dev version doesn't slow down a lot when loading the start of the gameplay on MK.
And last but not least, when checking the properties of the ISO, the disk transfer rate ticked, and synchronise GPU thread upped my speed massively. I guess the conclusion is that my CPU doesn't like working with my GPU at all.
I will try this with other games too.
