For Windows 7 users, the thing that made me upgrade to Windows 8 was Adobe After Effects:
- Impossible to use in Win7, the rendering for previews happened ssoooo extremely slow for each and every frame, that it was hell trying to build a composition.
- In Windows 8, on the same hardware, nothing at all changed, Aftereffects works like.. 1000% better (I KIDD YOU NOT!), and it's a real pleasure to work in it now.
How they've managed to bring such a ginormous improvement is beyond me, but GG Microsoft!!! and with such improvement on this part, it was easy to presume that such improvements exist throughout the OS, not only in this regard.
