It turns out that Bandai Namco is working hard to reduce, not remove, the nasty input lag being experienced in Tekken 7 on the PlayStation 4.
Yesterday, series director revealed that the problem lies with “certain wired pads” and a fix will be released in the coming weeks. Many from the fighting game community found it difficult to believe the developer because they have been using the same controllers in other games and platforms without any issues. This includes Tekken Tag Tournament 2 from the previous-generation, which is said to run far better than the latest installment.
The heated debate forced design director Michael Murray to clarify that the input lag in Tekken 7 is a combination of controllers, the hardware, and Unreal Engine 4. The revelation shines a new light on the matter. In short, the input lag of Tekken 7 cannot be completely removed since there are multiple entities involved. Bandai Namco can only correct issues from its side, and hope to work with Sony and Epic Games from their respective sides.
There were already reports from third-party sources that there is an eight-frame input lag in the game, supposedly put there on purpose by the developer for a seamless online and offline experience. Harada debunked this by stating that Unreal Engine 4 alone adds at least three or four frames of input lag, which the development team has no control over.
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

The next update is confirmed to arrive this week. It will make the situation better on PlayStation 4 by addressing wired controllers. However, as stated above, Tekken 7 will continue to run with some amount of input lag on the console due to the nature of the hardware and engine.
Hopefully, Epic Games will step in to address the problem. Unreal Engine 4 is a popular choice for many developers due to the very fact that it is budget-friendly. If it is resulting in lag for every title, then it is something that needs to be amended.
