Dolphin Progress Report: September 2014


Optimizations seem to beget even more optimizations. It was big news when last month we got a nifty 26% boost in CPU performance, but somehow, two dedicated devs managed to top it this month. Not to be upstaged by Fiora , comex has dropped new features and two absolutely gigantic performance commits. By making tricky use of registers and native RET behavior, two of his merges alone result in a massive 16% performance boost to games.

Not to be outdone, Fiora has continued her rash of optimizations as well. If we were to include every single one this progress report may never end. So instead, she crunched some numbers with all the optimizations over the last two months put together.

Let's just admire that list for a moment. The Last Story is considered the most demanding game on Dolphin, requiring massive overclocks on even the strongest of machines. A 38% speedup is the difference between it being playable and choppy for users with powerful computers.

Star Wars Rogue Squadron II: Rogue Leader has a lot of problems, but MMU performance will be the least of them from now on. Fiora's optimization of how the JIT handles MMU games brings us huge speedups to every MMU title!

Of course, speed isn't everything for an emulator: Performance is pointless if the emulator does the rest of its job in a lackluster matter. Have no fear, we have new features and some critical bug fixes to go along with Dolphin's newfound speed!

All of the latest features mentioned this month can be found in the latest development builds available here.
