Ok, I will possibly have to eat my underpants if I end up being wrong but I am willing to bet that Virtua Racing can be done on Amiga OCS at 30FPS (that is, about one third better than the Genesis's 20) and 16 colors (*). There are ways around the fill rate limitation of the blitter that I haven't tested/validated yet but which I think can give really nice results.

Now, I do not have anything but my imagination to back this assumption, so please be kind to remind me I said that in one year or two and I'll post a video of me eating my boxers on Youtube if I haven't produced anything.

I think i'm figuring out why Treasure Trap was so slow, as I suspect they lazily replotted EVERYTHING every frame!!
Just like good old Tiertex and other US Gold friends did back in the day.
Why bother using hardware scrolling when you can use the CPU to replot everything?

(*) Possibly with less polygons but still visually faithful to the arcade version.
