This is a list of notable features and support that Dolphin has dropped. The primary purpose of this list is to serve as a reference for those who want to revisit and explore interesting features that we have moved on from, as well as for historical documentation. Do not use these old features if you want performance - the latest development or beta builds will always be faster on modern hardware.  
This is a list of notable features and support that Dolphin has dropped. This page serves as a reference for those who want to revisit and explore interesting features that we have moved on from, as well as for historical documentation. Downgrading Dolphin versions for any one of these old features can be detrimental to performance. The latest development or beta builds made for modern hardware can give you best emulation.
