Three months ago, when I decided to give those 3D eye candy stuff a try, I couldn't work out Compiz so Beryl was installed and since that it occupies my desktop. Well occupied, I've just turned it off today. After some hype period when I enjoyed those 3D effects I've started to turn them off. I like the 3D cube, but the overall number of effects turned on by default kills the experience. For example those wobbly windows are really nice to see but not so cool to have it on all the time. There are still some features that actually makes the work-flow a bit harder compared to classical 2D management (I'm referring to semi transparent windows when they lose focus). I know these can be turned off, but this makes you go through huge list in Beryl menu (now I have to admit this seems to be easier with each release of Beryl).
On the bright side, the performance is great. On my Intel915 integrated VGA everything runs smooth up to 1024x768 and is still usable in 1280x1024. I was really surprised in a nice way, specially when a friend of mine told that Vista has those "wow" features as well but requires way more power to do that. Btw anybody running Vista? It has been out for few months and I still haven't seen it. Perhaps there is something true about Paul Graham's statement Microsoft is dead.
Anyway, 3D management is coming, no doubt about it. All is needed is better selection of default plugins turned on by default and it is back on my laptop for sure. Lets wait and see what brings recent announcement of merge between Compiz and Beryl projects. And why not give Metisse a try? It comes with latest Mandriva which can be obtained as a flash memory disk. True Plug and Play.
