i reckon some more optimisation could be done within the engine for the vu animations imo, its a bit random on the cpu usage depending on volume level and song,
would also depend on the amount of frames/layers within the vu's
might be worth experimenting with number of layers, size, content
- layers - say between 5 & 25 layers - wouldnt have thought it would make much more sense with more than approx 15 layers but an optimum number might well be good to determine
- size - again a small vu shouldnt take up hardly any cpu compared to a huge area due to the drawing/updating of layer and if its under other layers for example a glass or other layers
- content - a simple bar compared to a more fuller animation with lots of areas with transparent areas etc..
i think keeping layers/frames 10 or under shouldnt be too much of a problem with todays newer/next gen cpus but that also depends on what cpu you got in the first place
