When fps is fluctuating for no good reason.

That depends on how you look at it. Changing the option will change real fps which will fix/break calculation of displayed gamespeed/fps so that it's more/less accurate depending on whether the option is on/off.

Naturalviolence, please explain what vbeam is for me. I tried getting an answer for days but no luck.

we would need a good explanation from the person who implemented it first.

Now I'm curious, syncing up to the SVN to see if I can find it and figure out what it's doing.

EDIT:
Found it, looks like it determines which fields of the screen are being synchronized to catch some key differences between interlace and progressive scan modes. I have no idea why that's important though since my field of expertise is in Direct3D & HLSL for PC, not all that familiar with game console's internal workings.

If you tick the option, you'll get more FPS. (just try it with DKCR)

[SantaC]

but can vbeam cause glitches?

[IceD_X]

DKCR already tested... No improvement with VBeam...

I got a big speed up ~

look in the second map (1-2). Look FPS in the Waterfall zone.

Mine VPS and FPS are the same with or without VBeam.
