This game suffers from severe stuttering during shader generation. Because of the differences between how the GameCube works compared to personal computers, whenever something uses the GameCube'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 this game, 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.

=== {{s}}Refraction Slowdown{{/s}} ===

Refraction effects, such as raindrops on Samus' visor, cause slowdown in OpenGL. Even the strongest computers are affected by this issue, and there is no solution with the OpenGL backend at this time. D3D is not affected by this problem in this game. Fixed by {{revision|4.0-5124}}.

{{testing/entry|revision=7346|OS=Windows 7 x64|CPU=Intel Core 2 Quad Q6700 @ 2.66GHz|GPU=NVIDIA GeForce 8800 GTS|result=Playable: 30-60FPS with DX9 plug-in and Recommended Configuration. Just like Metroid Prime 1, if there are too many enemies, you will occasionally have some slowdown, especially since EFB copy to RAM is REQUIRED for the scan visor, which is an essential part of the game. Essentially runs flawlessly as of {{revision|7346}}.|tester=ShobuPrime}}

{{testing/entry|revision=7436|OS=Windows 7 x64|CPU=AMD Phenom II X4 955 @ 3.8GHz|GPU=ATI Radeon HD 4650|result=Playable: Runs fine except for occasional loading pauses and the scan visor. Using slightly tweaked config based off of recommended config.|tester=MechWarrior001}}

{{testing/entry|revision=7661|OS=Windows 7 x64|CPU=Intel Core 2 Quad 9550 @ 3.2GHz|GPU=AMD Radeon HD 6950|result=Perfect thanks to Dolphin DX 11 renderer without any issues and with the scan visor fully functional. 60FPS all the time.|tester=Xenon}}

{{testing/entry|revision=3.0|OS=Windows 7 x64|CPU=AMD Phenom II X6 1100T|GPU=AMD Radeon HD 6850|result=Perfect, just some slows when rain drops or water on the visor,audio some times crashes, graphics are clean and perfect|tester=Aldaris}}

{{testing/entry|revision=4.0-256|OS=Windows 7 x64|CPU=Intel Core i5-2500K @ 4.3GHz|GPU=AMD Radeon HD 7950|result=Near perfect. Some slowdown when jumping out of shallow water, or looking up at open sky, but neither are significant issues due to their rarity. The green dot and black bar bugs persist, but I've yet to encounter flickering or micro-stutter.|tester=}}

{{testing/entry|revision=4.0-1192|OS=Windows 7 x64|CPU=AMD Athlon X4 640 @ 3.15GHz|GPU=NVIDIA GeForce 9800 GT|result=Playable to completion with near-perfect emulation. Noticed some sound glitches when fighting Warrior Ing. Slowdown to ~20FPS when viewing map and during water splash effect. (Dual core/HLE/DX11/No enhancements)|tester=Durandal}}

{{testing/entry|revision=4.0-1720|OS=Windows 7 x64|CPU=Intel Core i7-2600K @ 4GHz|GPU=NVIDIA GeForce GTX 660|result=Crippling lag with water splashes seems to have been lessened quite a bit, now either causes minimal frame drops or none at all (Thank god, as I was in the Bog at this point); the same can be said for raindrops. Black bar issue appears to happen immediately, though, compared to some of the earlier revisions and the game still refuses to launch with "Sync GPU Thread" enabled. Game otherwise runs quite smoothly with no noticeable/reproducible issues|tester=TehGuy}}

{{testing/entry|revision=4.0-6426|OS=Windows 8.1 x64|CPU=Intel Core i5-2400 @ 3.1GHz|GPU=NVIDIA GeForce GT 610|result=Near perfectly emulated, some big open areas will slow down, interestingly not as bad as in MP1, black bar isn't a problem at all and in fact i didn't notice it until i checked this article. Automatic Resolution depending on window size, DX11, dualcore mostly 60FPS, Graphic config is based on an MP1 config and works just perfect, [https://www.youtube.com/watch?v=YSkdmrGOqao here the video].|tester=KerrangR}}
