![]() Mixed with the performance improvements from magumagu and skidau, some MMU titles are nearly twice as fast as just a month ago! The overall performance improvement of Fiora's "Faster MMU 2" was on the order of ~80% in the Rogue Squadron titles and significant amounts in other MMU titles. skidau started by fixing block linking to work in MMU mode, and then magumagu extended this by improving fastmem to support MMU too.įiora then painstakingly assembled roughly two dozen MMU-related patches, including optimized paired loads and stores, exception checking and TLB lookups while fixing a number of bugs that could cause random crashes in MMU titles. ![]() ![]() There were many changes revolving around two basic ideas: eliminate as much of the possible impact of the MMU on all code in the game that didn't actually use those features, and shorten the address translation code path, from memory loads and stores to their associated page table lookups, as much as possible. While there are quite a few MMU games, the goal was to get Rogue Squadron 2/3 near full speed on current hardware before it was playable. Regardless of all of her, and other developers, optimizations, MMU mode still remained a very demanding feature.ĭevelopers attacked the problem again over the past two months, with a goal of reducing MMU overhead as much as possible. So hold tight, and please enjoy this month's Notable Changes!Ĥ.0-4963 - Faster Memory Management Unit (Part 2) by Fiora ¶Ī few months ago Fiora as much as doubled the performance of MMU games through improvements like the "far code" cache, implementing paired loads/stores in MMU mode, and a few other tweaks. ![]() Thanks to a ton of work from the staff, tons of testing from the forum users, hardware tests, newcomers and veteran's alike, Star Wars Rogue Squadron II: Rogue Leader and Star Wars Rogue Squadron III: Rebel Strike are both playable and completable in Dolphin at long last.Ĭonsidering just how many big merges were changed and how much work was done that may not even be the biggest news of the month. ![]()
