In addition to all of that, compilers even generate better code thanks to the ability to do 64-bit memory operations without needing special alignment. 32-bit has to fall back on the CPU-intensive interpreter functions for most DSP instructions. Plus, since 64-bit is large enough to fit the DSP's 48-bit registers, it can run DSP JIT (Just In Time) recompiler for a nice speedup. This brings the emulator much closer to the number of registers to that of the PPC processor. Dolphin sees very important and observable benefits in its 64-bit builds! With a 64-bit address space, Dolphin can reserve a 4GB area that maps to GCN/Wii memory boosts performance greatly and, more importantly, 64-bit has twice as many registers.

This is not true with Dolphin, where some games still do not run full speed on any existing configuration. For those programs, the benefits of 64-bit don't matter much at all, and the end users need not worry about any of it! Most programs can have 32-bit builds and 64-bit builds without trouble or more commonly host only 32-bit builds and let 64-bit users use it as well. Any computer that needs 32-bit due to memory constraints or processor limitations simply won't run Dolphin at usable speeds, so what use is there in supporting it? Any computer that can run Dolphin is already using a 64-bit processor.ĭolphin's 32-bit builds are not indicative of the Dolphin experience It's only thanks to Microsoft selling 32-bit versions of their operating system that any sizable number of Dolphin users need 32-bit builds at all! Since 2003 when x86_64 processors debuted, the newer architecture has proven itself far superior to the original specs it was based off of. On the hardware side of things, x86_32 processors died a long time ago. Vista, Windows 7, and Windows 8 are all designed for 64-bit.ĭedicated 32-bit processors are very outdated and cannot run Dolphin at playable speeds The unintended side effect to that drop is that Dolphin no longer supported any operating systems that were primarily 32-bit. The aging operating system's days were numbered simply by that, and once the move was made to C++11, there was no going back. The only reason for dropping XP support is because the latest Microsoft Visual Studio Compiler doesn't support Windows XP. With a little under 10% of our users still using the OS, Windows XP was a significant share of our users, but at the same time the team made a decision not to let any particular OS hold us back.
Windows XP has been unsupported for monthsĭolphin has already dropped Windows XP support. But the past few months have seen a reoccurring theme: 32-bit builds break, and many of the developers question its worth.

From the insane to the mundane, hundreds of ideas will come and go every year as for how to make things better. The Dolphin Emulator team is constantly searching for ways to improve the development pipeline.
Despite that, we still find ourselves at a crossroads just a few months later. Well over one third of our Windows downloads for Dolphin 4.0 were the 32-bit variant a huge share of our userbase.
The cost being development time, maintenance, debugging, bandwidth, money and more, with the reward being a better, cleaner experience for our users. Maintaining features is a balance between cost and reward. Some choices require months of preparation, discussion, examination, while others are inevitable.

The emulator has become much more robust over time with support added for 64-bit Windows, Linux, Mac OS X, FreeBSD, and even Android phones and tablets! A lot of things have changed since then as Dolphin has expanded its goals.
It was a 32-bit Windows application that required Direct3D 9 with no alternatives. Ten years ago Dolphin was a very limited program designed to run in only one environment.
