Peter K's awesome new icon.library :)
Life begins at 100 MIPS!


Nice Ports on AmiNet!

I guess Peters Peter K's icon.library is available somewhere over at EAB.. Just had a quick google now..    Looks pretty sexy but still blends in quite nicely with the overall desktop!

Yes, there's a CGX driver for AGA, although I don't think it improves speed much compared to the typical patches. When I heard about it I thought "kewl! I'll have a Ham8 WB and will be able to run some apps in CGX 15bit screens!" but it doesn't have R5G5B5->ham8 support :_( Ham8 screens were slow in Fusion but quite cool.

The best thing to avoid slowing down your miggies is using screenmodes that don't use too many DMA channels: e.g. AGA 640x480 flicker free in more than 16 colours will use too many dma channels and will slow down chipmem access (no matter how many patches you use to make the problem less noticeable, the problem will remain there), AGA SuperHiRes screenmodes act like those productivity screenmodes, more than 16colours will slow down. 15Khz HiRes on AGA is no problem regardless of the number of colours (blitter will need more time to blit due to the higher number of bitplanes but cpu will be able to access chipram at full speed).

With OCS/ECS anything HiRes in more than 4 colours will slow down your miggy, MagicWB makes little sense in OCS/ECS machines. If I could choose an iconset I would use 1.x-style icons for OCS/ECS machines since the icons looked great (I love the white rabbit jumping over the turtle). For apps I would use separate screens with normal 2.x/3.x colours.

Interesting post. I disagree with the part about magic workbench on ocs/ecs. MB works very well for me with lower speced machines..
What about the new MK2 modes like Superplus and those? How fast is chipmem access?

And the most important question why do you have an avatar with Satanic imagery? Thats quite offensive and i'm sure against the TOS
