Seriously?
In many MP3 players, a few video games I can think of (like ClickBoom's port of Quake), most 3D graphic software...
If Gunnar is having a problem finding packages that can use fpu routines, he isn't trying very hard.
Plenty of MP3 player options that don't need an FPU to choose from and with 16bit sound likely to be added to the Vampires some players may be considered obsolete if not capable of 16bit support.
I would think that there would only be a handful of games that need an FPU.
I would also think there are only an handful of masochists still using an Amiga for 3D graphics work.
The main use of an FPU is likely in the demo scene. Anecdotally much of the hardcore demo scene community are said to be "not fans" of the Vampire as it's not original Amiga/Motorola hardware (even though they may be doing most of their development on PCs). I personally, while appreciating the skills of the demo creators have no interest in installing and running the demos, I'd just watch online videos if interested in them for some reason.
Given the circumstances it's no wonder that implementing an FPU on the Vampires is not the highest priority.
