New details regarding Tekken 7 input lag on console has led to questions about upcoming Bandai fighting game Dragon Ball FighterZ. According to DisplayLag, Tekken 7 is currently burdened with a hefty input lag ranging from an average of 7.7 frames on PlayStation 4 to 8.1 frames on PlayStation 4 Pro. Lag tester noodalls tracked a similar 8 lag frames on PS4. The Tekken 7 team is hard at work on a patch to improve where they can, but recent developer comments on Twitter have pointed towards a mix of the hardware and engine being at fault.
For just a cursory background, any input lag over 6 frames is generally considered less than ideal, whereas games approaching 4 are lauded. A difference of just four frames (less than 70ms) being enough to cause fighting game players extreme frustration should show just how much cutting even a single frame of lag can help. Higher input lag also usually goes hand in hand with different lag times for multiplatform games, which can split communities and make competitive scenes less viable.
Oddly enough, Tekken 7‘s input lag came into the spotlight due to players at first assuming it was an intended lag added by the developer. This can happen when a developer wants to create lag parity in online multiplayer, but Tekken 7 single player had lag as well. When asked if the devs would be removing the offline lag “buffer” in offline play, Tekken designer Michael Murray clarified that there was no buffer. Game Director Katsuhiro Harada then chimed in with specifics regarding how Unreal Engine 4 “eat” 3-4 frames, explaining the high input lag.
Yea It's wrong. UE4 eat 3-4frames & They don't know hardware side mechanism. We don't need such a "buffer". Measurement method is also wrong https://t.co/xVZMwazVFs

Which brings us back to Dragon Ball FighterZ, confirmed to also run on Unreal Engine 4. Note that for now fans anticipating the Arc System Works game are simply curious at this point. The studio has given little to justify worry as of yet. Yet when both Tekken 7 and Street Fighter 5 have launched with very high input lag, then it’s fair to recognize the trend. Street Fighter 5 has since shown that the lag can be cut down, but it’s safe to say that expectation for Dragon Ball FighterZ is set much higher.
The Arc System Works team working on Dragon Ball FigherZ is responsible for games including Guilty Gear Xrd and BlazBlue, both extremely high quality 2D fighters. Guilty Gear Xrd -REVELATOR- is known for having extremely low input lag on PlayStation 4, but it’s notable that it was made on Unreal Engine 3 and not 4. Clearly Arc System Works has both the experience and wherewithal to keep Dragon Ball FighterZ input lag low, unless Unreal Engine 4 is more troublesome than expected. And so, fans have questions. Hopefully we hear news soon.
Dragon Ball FighterZ will launch for PlayStation 4, Xbox One, and PC in 2018. Tekken 7 is available now on PlayStation 4, Xbox One, and PC.
