The feature, which was announced at gamescom for both Xbox 360 and PS3, will drop the frame rate from 60 frames per second down to 30.
"When we were developing the 3DS version of Tekken, one of the selling points was that it was still in 60 frames per second while it was in 3D," game director Katsuhiro Harada told Digital Spy at gamescom.
"Obviously for Tekken Tag Tournament 2 it's tagged, so you've got four characters on screen at once. It's very heavy on the graphical engine. The frame rate is divided by two because of the left and right side, so it drops to 30 frames.
"There are some good parts to that. For example, if you turn on 3D it's easier to judge the space in between yourself and walls and such, or see the techniques and how they're moving their motions and such."
A higher frame rate ensures smoother visuals and decreased input lag, which is important for fast-moving titles such as fighting games.
Also announced at gamescom was the Tekken World Federation service and a mode that allows you to select your own custom music for individual battle stages.
Tekken Tag Tournament 2 is a console port of the arcade game with an expanded character roster and new game modes.
It was confirmed at this year's E3 that Snoop Dogg will feature in the game as a non-playable character, having contributed music to the game's soundtrack.
Tekken Tag Tournament 2 will be released for PlayStation 3 and Xbox 360 on September 11 in North America and September 14 in Europe.
