Looks decent, however the rendering code needs adjustments. Almost 6ms are spent rendering 4 256x256 sources, which just isn't okay.
The rendering code of this plugin should undergo a clean rewrite, as there is no reason to render each element individually. Instead the author should build a vertex buffer large enough to fit each bar, and work with that instead. This would save nearly 95% of the time spent rendering, and free it up for actually important things - like the game.
