=== Performance ===

Performance in general seems reduced compared to the game's GameCube counterpart. This may be related to the higher resolution textures and various new screen effects added for the Trilogy versions.

=== Micro-stuttering ===

All of the Prime games suffer from micro-stuttering: screen redraws and small stops in the video that can become very annoying. It occurs in all graphics backends, but the OpenGL backend has consistently been the most resistant to the problem. DSP HLE and DSP LLE are both affected, though DSP LLE appears to make it worse in some revisions. Its severity varies depending on the revision and settings used, so if you want to play the game you should try a wide variety of combinations. Micro-stuttering can trigger the Black Bar glitch.

=== Black Bar ===

Whenever Dolphin has trouble with the game and flickers, from a loading hiccup to taking a screenshot, a black bar will appear on the bottom of the screen, taking up 15% of the screen space and "squishing" the game in the remaining space. This occurs in all graphics backends, and there is no known solution, but OpenGL is the most resistant. See {{issue|5185}}. Old versions of Dolphin, such as 3.0-135, do not have this issue on all backends.

=== Bloom Offset ===

Like Prime 3 and all the Trilogy games, Prime 2 Trilogy has bloom offset problems. Fortunately, it is not very noticeable with this game. There is no known solution to this issue. See {{issue|5573}}.

=== Refraction Slowdown ===

Refraction effects, such as raindrops on Samus' visor and the heat effect after firing her weapon for an extended period, 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. D3D11 and D3D9 are not affected by this problem in this game.

=== 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.

Visors will only work if EFB to Ram is enabled. However, EFB to Ram is set as default within the game INI, preventing the user from using anything but EFB to Ram for this game. Additionally, the graphics hack "Skip Dest. Alpha Pass" needs to be OFF for the Scan Visor to work.

=== <s>Audio Issues</s> ===

Several sounds don´t play appropriately, and sometimes music stops playing. Use [[DSP LLE]] to correct it. See {{issue|5563}}. Fixed by the merger of New-AX-HLE 2.0 in {{revision|3.5-1154}}.

=== <s>Wiimote Lag</s> ===

The game may experience a small amount of Wii Remote lag. Use "Alternate Wiimote Timings" in the game settings to correct it. Fixed and the option removed by {{revision|3.5-354}}.

{{testing/entry|revision=3.0-766|OS=Windows 7 x64|CPU=Intel Core i7-3770k @ 4.4GHz|GPU=AMD Radeon HD 6970|result=DX11 at 1900x1200 (using internal resolution auto, 4xAA), averages 50 FPS. EFB-copy-to-RAM must be used 100% of the time for the scan visor to function (contrast to MP1 where it is only required for the rarely-used x-ray visor), but fastest cache option can be used (causes very minor graphical glitches).  "Skip Destination Alpha Pass" also breaks the scan visor and should be left off.  "Accurate V-Beam" (in right-click options) provides noticeable speedup in large rooms with no ill effect. DSP-HLE works fine, except for very occasional loss of BGM (can be resolved by save/load or reset); DSP-LLE does not drop BGM but instead causes crackling and clicking sounds whenever framerate drops below 60 FPS. OpenMP texture decoder, cache display lists, and disable fog/per-pixel-depth are all recommended for slight speedup. DOL swap still required to run.|tester=anon}}
