Yep, those nice optimization.
I have no problems with 8. I've adapted.
I don't leave my computer on 24/7 in the past... I do now. That means a decently fast startup time so I can get right to my anime is important to me.
Hell, waiting for the first 5 seconds before the computer finishes POST and the UEFI splash screen shows and then finishes takes longer than it takes for Windows to load and bring me to the lock screen.
