Hi, it's a repost, but I thought that this should go here to. I've ported Grafx2 2.2 to Atari Falcon/TT. You can read about it and get it here. :)

Cheers,
Saulot

Nice one!

Curious question, is it just slooow and unusable on a plain Falcon with 14Mb or what is the exact bottle neck? I think, a basic Falcon should be able to run a similar art package. Is this a port of the SDL version?

I can do testing under a 4MB Falcon! :D

I assume the 14MB requirement is to do with FreeMint?

It's slow because it uses sdl and sdl needs serious horsepower. I imagine that native packages would be much faster but grafx2 is still being developed.

No works under MinT/TOS. It is usable on bare falcon (but fastram and accelerator helps alot), but some operations can be slow (like fx). And yes this is the SDL port, could be faster. Lowering the resolution could help. I've build the version for lower specs machines too (disabled layers).
Yes it could be faster I think if it was rewritten. In this case I think some asynchronous disk writes could help, because program writes alot to hd (backups, undo buffers and so on). Falcon video ram is slow sometimes.
It works very well with ct60, it could be better with radeon support (atm SDL isn't supporting fullscreen on CTPCI radeon) - you know bigger resolutions and more speed.
The cool about it is open project, I will merge my changes to SVN trunk soon so atari port will be official. If anyone can improve/test this program he is welcome. And thats it.

Indeed! Please make your port offical. Besides I think 320x240x8 is ok for most Atari related artwork.

*All thumps up* for your efforts!

Hi, I've just released GRAFX2 2.4wip with CTPCI/Radeon support.
http://nokturnal.pl/2011/08/grafx2-2-4w ... on-support.
It's based on my experimental SDL build. Latest drivers are required.
