When creating new threads about Dolphin, always provide your full PC specs (CPU, RAM, GPU, Operating System), information about the Dolphin build used (version/revision, source, etc), Dolphin settings and detailed description of what you're trying to do (e.g including the name of the game you tried to run and a screenshot/video of the issue if necessary). Ignoring this rule will get your thread closed and have you warned off.
