At 0.2ms things are pretty much virtually hardware. Things feel as responsive as a vintage Amiga 500, and then you have that whole crowd. And that low-jitterlevels inspired a generation of multimedia artists, we really don`t see today. Whenever someone nostalgically mentions Amiga, it is mostly because it is a low-jitter machine. Non-interrupted animations, instant sound when key pressed. That pretty much raises the overall computing experience, to where quality software is more likely to happen. And I do believe that is why that happened on Amiga.
Ofcourse also arcade-machines without jitter, might be more a comparison today. For instance Virtuafighther etc. Well it`s been a long time ago since I played arcades, but Doom 3 feels more like a hardware arcade, than any dull highlevel-PC. Which also means that highlevel-programming has reached the point of virtually being similar to assembly-coded hardware, which I also find to be an interesting point.
Peace Be With You.
