If you play an "OS friendly" game on the Amiga, it might have studdering issues, too. You can only get guaranteed performance if you disable multitasking. Of course, this defeats many of the reasons for having an OS in the first place, and is not an acceptable option these days.
The Amiga could smoothly scroll text in a window that wasn't the focus.
If you run the DirectX test suite, you'll almost certainly get perfect vsync with no studdering at all. I never get studdering when running the test. Ever.
OK Direct X seems to be the only way too get smooth video.
So why don't apps like Powerpoint make use of it?
My take is that people just don't care about refinement these days. It's all about max framerates and bragging rights. If Microsoft were to make changes to Windows so video performance were more consistent, but was slower, you'd better believe PC enthusiasts would b**ch about it to no end.
I would think people would like change that made a noticeable difference. eg. A media player that scrolled long media titles completely smoothly. vs encoding mp3 2% faster.
PC hardware today isn't what PC hardware was 20 years ago. It doesn't suck anymore. The last remaining Amiga enthusiasts still haven't figured that out.
New PC hardware certainly does not suck. But the user experience most certainly still does suck. eg. clicking on a menu can sometimes take several seconds while on a Amiga it was instantaneous. Putting a disc in causes a PC system to stop.
