Shader Compilation Stuttering
Star Wars Rogue Squadron III: Rebel Strike Limited Edition Preview Disc 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 ubershaders. Changing GPU, updating GPU drivers, or updating Dolphin may invalidate the shader cache, requiring specialized shaders to be compiled again., this problem can be solved by enabling
GameINI Detects Incorrectly
In the Dolphin front-end, the Rebel Strike preview disc will be detected as the full game and display the wrong name. It also automatically changes settings required for Rogue Squadron III: Rebel Strike which may not be optimal for this preview disc.
This title doesn't need non-default settings to run properly. A full list of config options is available here.

This title has been tested on the environments listed below:
|Ubuntu 14.04||Intel Core i3-3220 @ 3.3GHz||NVIDIA GeForce GTX 650||Dolphin incorrectly detects the preview disc as the standalone game and applies gameini settings. The menus all work but can slow down to around 80%. The playable Hoth stage from Rebel Strike did not work, after choosing the stage the emulator displayed pink and green garbage and then crashed entirely. The playable Star Wars arcade game is inconsistent: first try it was at 90-100% and then freezed during play, the second try it was at 50% and I was able to complete it. All movies/trailers work perfectly with zero issues.||Xerxes|
