ShadowKiller X has been discontinued
Email me when discounted: 
ShadowKiller is a hack that kills all shadows in Mac OS X (including window shadows, menu shadows, and so on). This speeds up Mac OS X on slower computers (see xlr8yourmac.com user reports linked from our support database - "Can ShadowKiller make Mac OS X run faster on my old model Mac?").

What's New

Version 1.3:
  • ShadowKiller is now a Universal application, working natively on both PowerPC and Intel based Maces
  • Fixed an issue with multiple screens when secondary screens were not refreshing immediately
  • New icon (from Sapphire set by IconDrawer).

Requirements

Mac OS X 10.2 or later

Thank you very much Unsanity.
I tested it on a PowerBook G4 "Ivory",
with Mac OS X 10.4.6, and I already
tweaked everything so that it runs as
fast as a G5 Double Core.

And this hackie even improved it more,
this is unbelievable, but true,
all my windows open twice as fast.

To the previous authors:
Please do not consider loading of
the contents of a window as part
of the loading time, because this
is not the part of the core image processing,
but depending on the system processes
and of course the dozens of contents.

This does really improve everything.

And I must say, that it does not look
ugly, instead it looks clearer to me.

Thanks!!

Your single G4 runs as fast as a dual G5? You should patent the process and sell it, there are lots of G4 users that would love to get that kind of performance. *rolls eyes*

i'm not sure if this is necessary with most macs now running Tiger. Since core image has moved much of the GUI processing onto the graphics card.

I really didn't notice any change in speed. If anything, it might slow down by decreasing my perception of window position!

Nice idea, and it does work as far as turning off shadows, but I really don't think it improves anything.

It makes it difficult to distinguish the edges of windows. A good solution would be if the windows could just have a solid border (rather than no border).
