Software News   Software News : Better quality AmigaOS4 Video of native P96 drivers
   posted by MikeB on 12-Jul-2004 6:04:29 (8686 reads)
Due to criticism regarding Crisot's first video, the beta-tester created a new video (24.7 MB file) to demonstrate the speed of OS4 running with a native version of P96 combined with an accelerated Voodoo 3 driver. This version shows almost no flickering and also shows Quake launching and running.

Like with the previous video this is not an official OS4 demonstration.

In AmigaOS 3.x icons are reloaded every time drawer window is opened, They are not cached, there is no icon cached in the memory, there is no icon cacgh in AmigaOS. I would quess it's same with os4.

With icons being cached I meant:
are ALL the icons(the bitmaps) cached when the directory is opened or are only the icons loaded that are actually (totally or partially) visible?
So if the user scrolls the icons that were visible and now are not visible anymore are erased from cache.
Or are only the icons loaded that are visible and if they are scrolled to not visible they are kept in cache(so only icons that weren't visible previously have to be loaded).
That's a bit what I wanted to know

Sorry for my English

Icon handling in Windows is a bit different. First there are no icon files. Icons are mostly default icons, and types are recognized using the file extension. When opening a folder, windows read all files and draw icons in one pass using default icons and then icons are replaced when file type is recognized.

Amiga has icon files. File type recognition is not only based on extension but actual part of the file is read so you cannot fool it just by changing extension (well it is the case with deficons in os 3.x, I hope it still is the case). When opening a drawer, files are drawn as soon as they are recognized.

@Ryu

Thanks for that mister.


OS4 & a PPC P96 look very nice indeed. Congrats to everyone involved.

Ok, Speed comparison to Windows XP. AmigaOS isn't necessarily faster, it just does it better.

I'm runnin XP on an Athlon 3000+ with 1gb Ram as I type this. I open up C:\Windows. The window freezes with a busy pointer as the contents are loaded in list view. I then switch to Icon view. The switch is a snap but as soon as I scroll I get a delay while the icon images are loaded. WindowsXP feels jumpy not smooth.

The difference is that the multitasking in AmigaOS is far superior to that of WindowsXP. I am constantly running into applications in Windows that HOG system resources and make everything else respond slower. AmigaOS handles this much better.
