While we are no longer suffering through Street Fighter V‘s eight frames of input lag, many modern-day fighters are still struggling to reduce input latency. Marvel vs. Capcom: Infinite is clocked at having exactly six frames of input delay — at least on the PS4 version — meaning that some developers have yet to crack the five frame barrier.

Much of this stems from these games running on Unreal Engine 4, which natively has around three to four frames of input lag. As a result, fighting game developers already have an uphill battle in making games as responsive as possible. However, an upcoming update to Unreal Engine 4 aims to cut its native input latency by around two frames for games running at 60hz.

According to Unreal Engine developer Epic Games, the 4.19 update to Unreal Engine 4 will reduce input latency “by around 66ms” for 30hz games, with “the reduction [being] around half that in a 60Hz title”. With a single frame being around 16.667ms, we’re looking at a potential two frame input lag reduction for any fighting game running on Unreal 4.

This is not a direct reduction of course; developers will have to do some work on their end to utilize this engine optimization but it bodes well for those wanting hyper-responsive fighting games.
