I have VU Stealing at 1, too, just to be sure, and the game runs really well. However, I can't help but I feel I'm not getting a smooth 60 FPS, even though the emulator stats are telling me I am. Perhaps that is the VU Stealing being noticeable, I'm not sure.
But other than that, changing that audio setting has rendered a huge performance upgrade for me. Even the craziest runes don't lag now, which is a great improvement from before where nearly every rune lagged.
VU stealing will cause internal frameskipping so it will lower the internal FPS(the fps PCSX2 reports is VFPS which is not the same as internal FPS). Don't set it if you don't need it.
The reason it exists though is because our VUs have basically no timing, unlike real PS2 ones. Ours run any VU microprograms as fast as they can and as soon as they are received. For most games this works fine, but some games continually feed the VUs as long as the previous program is "done." A real PS2 is limited by it's hardware speed. But PCSX2 is not and so in those cases it will just get hammered. VU stealing will offset this, but it will also again lower internal FPS as the game thinks the "PS2" is "busy."
