Dolphin is an incredibly impressive project - not just from a technological standpoint, but also from an organisation one. They post regular, detailed development updates, have in-depth release notes that are still entirely readable for laypersons such as myself, and you always learn a ton of new stuff following the project's progress.
A great example of how to run a project like this. Don't forget to check out the release video with tons of side-by-side examples of the long list of improvements.
The long awaited Dolphin 5.0 release is finally here! After nearly a year of bug-hunting and handling the release process, everything has come together for our biggest release yet! The three previous releases followed a very distinct pattern: sacrifice performance, hacks, and features in exchange for higher accuracy. As such, Dolphin 3.0, 3.5, and 4.0 progressively grew slower. But thanks to the cleanups put forward throughout those releases, Dolphin 5.0 is the fastest Dolphin has ever been! By removing all of those hacks and outdated features while cleaning up the codebase, Dolphin has reached a new level of efficiency, powered by a revitalized dynamic recompiler. On the GPU side, OpenGL and D3D11 have seen tons of optimizations and accuracy improvements, and have been joined by a brand new D3D12 backend for huge performance gains. If there's a CPU or GPU extension that can make Dolphin faster, we take advantage of it.
