performance drop after update

[pitblau]

I have updated dolphin from 3.5-367 to latest 3.5-1722 in my Macmini (mid2010), but I have experienced a dramatic performance drop in the emulation.
Before the update the New Super Mario Bros ruled well, but now it is unplayable.

How should I configure dolphin in order to retrieve past performance?

Thanks in advance!

You can't, dolphin has gotten slower over time.

^This. Generally speaking, the more accuracy is added to this emulator, the more powerful you need your computer to be. This, of course, is a generalization to show a trend and not an outright build by build statement.
