Metroid Prime 3: Corruption is a first-person action-adventure game developed by Retro Studios and published by Nintendo for the Wii video game console. It is the tenth game in the Metroid series, and the final entry in the Metroid Prime Trilogy. The Wii Remote and Nunchuk devices are featured in a new control scheme that took a year to develop and caused the game's release to be delayed several times.

Gameplay for Metroid Prime 3 is similar to its predecessors: players explore open ended worlds, finding story clues and power ups, solving puzzles, jumping on platforms, and fighting enemies. Unlike past games however, the game is divided into several open worlds; each world is smaller than the single open world environments of Metroid Prime or Metroid Prime 2, but the combined size is greater. As with Metroid Prime 2, exploring the worlds is not aimless: players explore the world freely, but there are specific tasks meant to be accomplished on each world which are told to you beforehand. The game also includes hypermode, a phazon overload system that allows players to exchange health for massive damage. The biggest change is the controls. Metroid Prime 3 uses a new control system using the Wii Remote and Nunchuk, allowing free aiming and movement similar to mouse and keyboard controls.

Metroid Prime 3 was also included in Metroid Prime: Trilogy, which includes updated versions of its prequels: Metroid Prime and Metroid Prime 2: Echoes.

Emulation Information

Shader Compilation Stuttering

Metroid Prime 3: Corruption (Wii) is one of the most susceptible titles to shader compilation stuttering. The GC and Wii have no concept of shaders - everything is executed directly by the hardware without an intermediate programming language (API). Modern computers and mobile systems do not work in this way, requiring the use of shaders as an intermediary so your system's GPU can perform the tasks that the GC and Wii GPU performed directly. Shaders have to be generated though, and since GC/Wii games are not designed to create shaders ahead of time as a PC game would, when a new effect appears Dolphin has to delay the CPU thread while the GPU thread performs the compilation; a pause that does not exist on the consoles. For most games shader generation takes only a few milliseconds, but for a few demanding titles, the shaders that they generate are so large that they can result in noticeable stuttering, in severe cases pauses of over a second may occur.

Since 5.0-4869, this problem can be solved by enabling ubershaders. Changing your GPU, updating your GPU drivers or updating Dolphin may invalidate the shader cache, requiring specialised shaders to be compiled again.


Problems

Constant Wii Remote Disconnects

Since 3.5-471, when using the MS Bluetooth Stack (the default bluetooth stack on Windows) Prime 3 will think that the Wii Remote is constantly disconnecting. Pressing a button on the Wii Remote will restore it, but it will disconnect again seconds later. Windows users can disable "Enable Speaker Data" to solve this problem, or move to either the Toshiba Stack or the DolphinBar.

Bloom Offset

Prime 3 has noticeable bloom offset problems. It will have several copies of the bloom spread out from the source, and can be very distracting. The only solution is to disable "Scaled EFB Copy", but this has some issues of its own. See issue 5573.

Visors

The Scan visor will only work if Store EFB Copies to Texture Only is disabled. Though Store EFB Copies to Texture Only is forced off by the GameINI, visor issues may still occur if the graphics configuration window is opened during gameplay. Disable Store EFB Copies to Texture Only in the Dolphin GUI to avoid any problems.

Dot

When playing above 1x Native internal resolution, there is a dot in the center of the screen. It's small and easy to ignore, but it's always there. There is no fix for this problem.

The Black Bar

If the CPU and GPU threads of Dolphin desync too much during lag, a black bar may show up at the bottom of the screen. It takes up 15% of the screen space and "squishes" the game in the remaining space. The black bar will remain there from then on whether stuttering continues or ceases. Because shader compilation stuttering is the main cause for these desyncs on a powerful computer, enabling Hybrid Mode Ubershaders or Exclusive Mode Ubershaders should help with preventing this issue. Enabling Single Core will remove any risk of this issue occurring.

Test Entries
Revision OS Version CPU GPU Result Tester
r5442 Windows 7 Intel Core 2 Duo E7300 @ 2.6GHz NVIDIA GeForce GTX 275 Intro slow, but in game full speed.
r7111 Windows 7 Intel Core 2 Quad Q6600 ATI Radeon HD 5770 20/40 frames
r7478 Windows 7 Intel Core i7-2600K @ 3.4GHz AMD Radeon HD 6950 Works great. Real Wii Remote errors. Have to use emulated Wii Remote. Robodt7
r7670 Windows 7 Intel Core i5-2500K @ 4.1GHz AMD Radeon HD 6850 Runs flawlessly. 60FPS all the time. Still has Wii Remote control lag issues. Red blooming from light sources now fixed. MegaJump
r7670 Windows 7 Intel Core i5-2500K @ 3.3GHz NVIDIA GeForce GTX 560 Ti Struggle to reach 60FPS. Enabling any kind of anti-aliasing has a serious hit on performance 20-40 frames on 4x internal res. boeoz
4.0.2-2879 Windows 8.1 Intel Core i5-3570K NVIDIA GeForce GTX 660 Ti Game runs fine but slows down a lot in some places. Sometimes only the sound gets a little bit laggy but the graphics are okay, sometimes both are laggy. Map almost always is laggy. Reducing Internal Resolution helps, but not much. HLE seems a little bit better, though it suddenly stops in some cutscenes. Thales
4.0-4167 Windows 8.1 Intel Core i5-3570K NVIDIA GeForce GTX 660 Ti Running just fine! Great improvement from last test. No major slowdowns and no visible annonying glitches, at least with my DSP & graphics configuration. Thales
5.0 Windows 10 Intel Core i7-6700K @ 4GHz NVIDIA GeForce GTX 670 Game runs perfectly! "need a strong CPU" 60 FPS all time no slowdowns, no problems at all. Peach
5.0 Windows 10 Intel Core i7-6700K @ 4.6GHz NVIDIA GeForce GTX 1070 "UPDATE" Just got my GTX 1070 and game is running on 4K 60 FPS !! + i7 OC at 4.6GHz

Game is running so perfect idk what to say.
