Once again, and finally, it looks like it's really happening: the looooong overdue update of the Amiga's screenmodes and connection capabilities in regard to modern displays.
Additionally, some programs - probably mostly games - will benefit from this new stage of Apollo-core in a specific way: due to not only the super-fast CPU-emulation but also the new AGA-emulation both residing on the Vampire now, there's no need for "turtle mode" anymore - in other words: the CPU doesn't have to wait for the slow Amiga-mainboard chipset blitter anymore, giving huge performance boosts to blitter-heavy applications.
AGA chipset emulation is still work in progress (e.g. currently PAL only), and hasn't been released to the public yet, but you can already watch some impressive demo videos:
