No, you are incorrect. A non-FPU version of Mapparium called MUIMApparium was created with the Vampire in mind. The author also created versions for MOS and AROS.
Thats actually not true, the only reason I had "Vampire in mind" is because thats my only real Amiga with a GFX card. So to test the speed I only have that to try. UAE is very unreal
and sadly there is no other GFX card for keyboard Amigas currently.
(This was my main reason to buy a Vampire, the GFX card)
I got response from people use MUIMapparium with 68060 and GFX Card (even one crazy guy use it on a 68030, notice also no FPU here).
The implementation was also not triggered by Vampire, I wanted to learn MUI/Zune and overcome some (speed and not speed related) problems on all Platforms. The initial implementation was done with ARM-AROS on a Raspi3 (on vacation, a little computer to take with me). The Video for it was just to show that it is even fast enough to make it run on a real Amiga, no relation to Vampire. (as I said just because its the only one with GFX card) so on the NG platform it will just be very smooth, but this is hard to show in a video.
I really like my Vampire (and MUIMapparium :lol:) but to take MUIMapparium as a example program for Vampire is a little bit strange. There is no special stuff inside for Vampire and will never be.
The thread you mentioned there is the MUIMapparium thread I guess, which was not opened by me, I just responded to it and later add some updates because some people asked for it.
But what I did especially for Vampire was testing the FreePascal compiler... There should be a thread as well from me. I even thought about to include some better support for it on the long run (AMMX,..), ... now... nah ... you you can guess how big my motivation is to do something on this topic.
