The upcoming update 4.19 for Epic's Unreal Engine 4 may soon lower the input-latency of fighting games such as Street Fighter V
and Tekken 7.
This information was recently shared by SRK in relation to the recently published information on the engine's 4.18 update which also provided some information regarding the upcoming 4.19 update.
"While working on Battle Royale we identified some issues with input latency in the engine that particularly affected 30Hz games. We were able to make improvements to thread synchronization, reducing latency by around 66ms (the reduction will be around half that in a 60Hz title) to address this problem." - Unreal Engine
This information according to SRK will likely to reduce input lag by up to two frames for fighting games powered by Unreal Engine 4. This is great news for the Fighting Game Community. Street Fighter V's latest input latency rate was around 5.3 frames on the PS4 based on the test performed 4 months ago, while Tekken 7 has 8 frames on PS4 based on the latest Reddit discussion. Unfortunately, there's not much information on when these improvements will be delivered, still, it's great to know that this issue is being looked at by the developers. Stay tuned for more gaming news and updates.
