Many of us have motion blur headaches from the motion blur of 60Hz.

If that were the case, then movies, TV shows, YouTube videos, and low frame rate games would cause headaches, and changing the refresh rate won't help with those. Regardless, if someone needs a high refresh rate laptop, then they should get a high refresh rate laptop.

It also even reduces non-strobed LCD latency too with certain sync technologies, especially if you're using Scanline Sync with the tearline adjusted to near bottom of VBI so it's a "end-of-VBI Present()" replacing VSYNC ON's "beginning-of-VBI Present()".

This is too complex of a topic for release notes that many people don't bother reading. I can include a link if you have one. QFT wouldn't reduce latency with vsync off or FreeSync/G-SYNC on with the default range, which are the two most common modes that gamers use. If present happens at the beginning of VBI with vsync on, then QFT would actually increase latency because the start of the frame output would be delayed. Present would need to happen at the sync pulse or near the end of VBI to decrease latency, as you described with scanline sync.

Ideally it should have said "Quick Frame Transport" because it is universal, not just for strobing, but I'd settle for just appending "(QFT)" to make sure users get that assocation. Instead of something obscure like "Vertical Total Calculator".

I feel like QFT is the more obscure term, but I might change it to "QFT calculator (back porch)" so I can add "QFT calculator (front porch)" as an option, although I'm not sure which would be more useful.
