Microstutter with Vsync? I don't ever use Vsync, could you explain what you mean?

Meaning gameplay isn't as smooth as it should be or would be with a single card. There is a reason that people have been using a hard cap for years to eliminate microstutter. Vsync alone doesn't do it.

Runts are the only "major" issue with AMD cards though. If runts were entirely removed, Nvidia has only a marginally smoother experience, it's essentially invisible in a blind test.

I don't think that is true. They need to fix the timing issues that allow these runts to take place. These timing issues still manifest in other ways.
You can't have a runt frame with vsync enabled yet it clearly isn't as smooth as it should be. There has to be some other timing issues.

Here is one discussion about it on Rage3d.
