Developed: since August of 2008 Summary: Windows effects engine and customization tool. It offers various visual windows effects for such events like minimize, moving window and other. Description: Adds eye-candy effects to windows (and start menu) like deformations (e.g: jelly windows - that makes moved window wiggle like being made from jelly; or fold - which hides windows by folding up horizontally, and unfolds when showing), physics (e.g.: keep momentum - making window to conserve move momentum; or bounce - that makes windows bounce upon receving focus ) and other SFX (e.g.: pixie dust - which makes moved window to leave a trail of twinkling pixie dust; or close puff - which displays puff cloud below cursor when closing window).
If by "eat" You mean memory usage, then it depends what would You classify as "a lot" and secondly what allocation aspects You are taking under consideration when measuring it
Everything should - except for effects requiring thumbnails support (transitions could be working - if secondary thumbnail service mode was not voted out).
and secondly what allocation aspects You are taking under consideration when measuring it
P.s.: Oh and those can be faked
Secondly, did You choose version proper to Your processor architecture?
My processor is. Intel Celeron E3400 2.60GHz CPU :: ::. Which version should I use?

On version - depends on installed operational system (x64 or x86).
