Foobar2000:Components/Chronial's Coverflow (foo chronflow)
Coverflow... This plugin is still in beta developement and should not be used if you are affraid of bugs or crashes!
To understand the effect of the settings in the performance tab it is important to know the basic architecture of the plugin:
The plugin has two threads - one thread to render the image on thread to cache the cover textures.
The image will only be rendered when it is needed - eg. when you restore the foobar window, new textures have been loaded or an animation is shown. While foobar is minimized or completely hidden behind any windows the renderer will do nothing at all and so also cause no load for your cpu.
The texture loading thread loads the covers from you hard-disk into memory so the rederer can display them. This is done in an asynchronous manner (you can see this by scrolling very fast - the covers move faster than the loader can load them -> you see the "hourglass cover"). See #Texture Cache for further details.
These Settings influence the quality of the generated image. While multisampling only increases the smoothness of the cover edges, supersampling also does increase the cover resizing quality. But while multisampling only increases the load on the GPU, supersampling also increases the load on the CPU. For both of the more passes means more quality, but also increased GPU/CPU+GPU load - supersampling with 2 passes should yield enough quality and settings above 4 should barely make any difference. You should not use 16 pass supersampling, as it is very CPU and GPU intensive (the image is rendered 16 times!).
Changes to the multisampling settings will only take effect after the panel is restarted (either hide and show it or restart foobar)
