I have the same problem with stuttering despite a constant 30/60 fps in games. No matter what setting (individually tested) I use in Dolphin, there is just nothing to smooth out the frames. The only games I have tested are Xenoblade Chronicles (smooth in the early days of 3.0), Skyward Sword (currently playing), and Super Mario Galaxy. 30 FPS games seem worse than 60 FPS, but it's still apparent in all of them. I should note that it is most apparent when moving the scene around more so than anything else and happens despite being on the lowest IR setting or highest.
Outside of Dolphin settings, I messed with older drivers such as 332.21, 334.89, 335,23, and the one I am currently on, 337.50. Other than degraded performance, there was no change to the inconsistent frames. I also tried single monitor versus dual, maximum power settings, aero on and off (though it does help some), etc. Despite games being playable it really ruins the flow of games when it feels like frames moving slower than usual.
I know Dolphin is constantly being updated, and I do not like sounding whiny since I really am grateful for this emulator, but this feels like a more recent issue. I played through almost the whole of Xenoblade in 3.0 and 3.5 without any hiccups other than the obvious shader cache loading. It seems so apparent now that it is hard to ignore. Anyways, I did not reply to this post to ask for help or advice; I just wanted to add that I have tried nearly everything I can think of, like you, and still have the same stutter at max fps.
