Amiga Animation and CHIP RAM versus FAST RAM

[Britelite]

Page-flipping is perfectly possible at full framerate on both machines (well, any machine really), only limit is of course the available memory. I'd say the piece of Amiga-software you tried was limited or badly coded, because there's no reason for page-flipped animations to be less than full framerate.

So no reason to blame chip-ram or the clockspeed, a page-flip takes a few cycles and therefore doesn't require any CPU-power at all.

As for the Amiga- Well Im not sure about it's 4,096 color HAM-6 mode or it's 32/64 color modes being able to page flip at 60fps at 320x200.  Amiga clearly was graphicly more capable overall, but I'm just curious if the software or demos ever did 60fps for the Amiga 500/1000/2000.  That's all.

Is it so damn hard to understand that the hardware is perfectly capable of full framerate pageflipped animations? I don't know why the few pieces of software you used didn't allow you to do this, but they probably had their reasons. So to put an end to this discussion: both the amiga and st (and 99% of all other computers) are able to flip screens at full framerate. The only limitation being how much memory is available for the individual frames.

He's talking about minimum of 320*200*16 frames.  He can't be talking just about changing pointers of the display memory since that would only allow for 32 frames even on a 1040ST.  Perhaps, if you have an animation running at 60fps on an Amiga 500, you can give him a link.

No, he IS talking about pageflipping animations, which IS just changing the pointers in memory.

We are trying to understand him not pick on some word he used-- "page flipping".  You do see that he claimed 320*200*16 frames and on an A500 and Atari 1040ST?  Let him speak for himself as to how many seconds was the animation.

Well, he was mentioning Spectrum 512 animations as an example of stuff running at 60fps on his ST, and somehow I doubt those are done by any other method than pageflipping + a tight loop for the colorswitches. He also mentioned running animations on a 4MB machine, which can fit quite a lot of frames (as it can be used as gfxmem, in contrast to the 512/1024kB limit on the OCS-amigas).

And finally, I'm giving him the benefit of the doubt and assuming he actually has a clue, and therefore if he talks about pageflipping, I assume he knows what it means
