Title: PowerIcons faster
Post by: swift240 on August 23, 2006, 08:37:10 PM
On my real Amiga 1200 towered with mediator I am starting to change over to PowerIcons.
I have so far changed my Disc Icons to PowerIcons then changed all my draw Icons to the same PowerIcons draw types (folder looking type)
I now notice a speed increase when loading in.
My workbench is now faster using PowerIcons than using GlowIcons.

Has any one noticed a speed increase using PowerIcons?

Mike.

Yes, for some reason PowerIcons is faster on my A1200/060/Mediator than NewIcons.

Same here
But if you'll start using IconBeFast from Aminet my guess is that Glowicons will be faster :D

Can IconBeFast not also be used to speed up PNG icons?

Read in the docs of IconBeFast what it does and then remember that PowerIcons needs a truecolor screen mode (which works without pens). Do you still think IBF can speed up PNG icons ?

 So, the next question about this would be like: "How it is possible that 32bit .png icons are faster than 8bit .icon ones?"

Because PNG icons are displayed as-is, without any calculation while GlowIcons have to be entirely recalculated and dithered into the screen's palette. The only calculation done for PNG icons is alpha blending. Obviously Elena's alpha blending algorithm is much faster than icon.library's dithering algorithm.

Interesting!

But do the PNG icons use up more memory than the Glowicons?

IS it still worth installing IconBeFast on a grfx card powered Amiga?

PNG icons consume only fast ram and if done properly alpha blending is not necessarily slower than other rendering routines.
