== Problems ==

=== <s>Savestates</s> ===

=== Constant Wiimote Disconnects ===

Since {{revision|3.5-471}}, when using the MS Bluetooth Stack (the default bluetooth stack on Windows) Prime 3 will think that the wiimote is constantly disconnecting. Pressing Alt-F5 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.

=== Shader Generation Stuttering and the Black Bar ===

This game suffers from severe stuttering during shader generation. Because of the differences between how the Wii works compared to personal computers, whenever something uses the Wii's GPU, Dolphin must generate a shader to emulate it on a PC GPU. Shader generation causes a slight emulation delay while it's being created, so Dolphin caches these shaders in its shadercache folder to help keep things smooth. Most games don't care about this and play fine, but with ''Metroid Prime 3'', the shaders are so massive that they cause a significant delay, which creates a hard stutter and desyncs the GPU and CPU threads. The game freaks out over this desync, creating a black bar at the bottom of the screen, which 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. Going into new areas or showing new effects will cause the stutter and black bar, as well as going in and out of fullscreen and even taking a screenshot. Building up a shadercache of an area helps, but it will still stutter and desync if a new effect or region is loaded.

=== 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 ===

Visors will only work if EFB to Ram is enabled. Though EFB to Ram is forced by the GameINI, visor corruption may still occur if you open the graphics configuration window during gameplay. Turn on EFB to Ram in the Dolphin GUI to avoid any problems.

{{testing/entry|revision=4.0.2-2879|OS=Windows 8.1 x64|CPU=Intel Core i5-3570k|GPU=nVidia GeForce GTX 660 Ti|result=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.|tester=Thales}}
