Maybe the new technology uses better algorithms that make better use of current hardware.I'm actually sad about this - kinda wish they were forcing an upgrade, would mean the tech had advanced in terms of graphics.
Or... actually... it could just mean it's poorly optimised - I doubt that though, FD have lways been very good with presentation
Like a graphics card for many years receives many new drivers.
Strong improvements are possible with new technology. Look at the different versions of operating systems and other apps and games, with the same hardware.
Of course that won’t prevent from buying new hardware to enjoy even more this new technology, I guess.
