Update: DisplayLag's Adeel Soomro uploaded their findings from testing the new Street Fighter 5 update for input delay in video format. They note that their results show an average of 5.3 frames of lag which they say pretty much match WydD's, as DisplayLag includes the delay from monitors while WydD does not. You can find DisplayLag's video test after the jump.

The moment we've all been waiting for seems to be here as we finally have an answer to how much Street Fighter 5's input lag is being reduced.

We got word from Capcom back on October 9th that said delay was going to be reduced, but received no detail in terms of by how much or if the heavy fluctuation rate would be addressed.

WydD has mined the data from today's update patch and posted his findings on Twitter, and his results say the game now runs with a 4.41 frame delay and a 77% stability rate on PlayStation 4.

"Better, obviously but not great," he concludes. "There are still some moments of instability (here I'm selecting only timings < 15ms for better viewing) very similar to Soul Calibur 6.

"As I recall Dragon Ball FighterZ, Tekken 7 and King of Fighters 14 are all rank B. Ultra Street Fighter 4 is rank A. So technically SF5 is +1f compared to SF4."

The new numbers for Street Fighter 5 place it just above other fighting game titles Tekken 7, Dragon Ball FighterZ and King of Fighters 14, meaning it now has less delay than said games. Below are WydD's table and graph depicting the finer details of the update:

One of the major issues that came along with the large input delay was the fact that it would fluctuate mid-match, meaning that sometimes inputs came out faster than other times.

Capcom has addressed this stability issue, and while Street Fighter 5 still doesn't reach the same levels of consistency that predecessor SF4 had, it does mean that SF5's input lag will now only fluctuate between 4-5 frames.

The French computer science PhD's previous findings for the game clocked it in at around 5-6 frames of lag and a 43% score for stability, as seen in the graphs below:

We've recently addressed this hotly discussed topic on a recent episode of the EventHubs Podcast, and have also been polling our readers to garner their thoughts on the severity of this update as well as how much it will affect individual characters.

Here are DisplayLag's findings, please note that the frames are doubled because the video is in slow motion and running at 120 fps. The numbers in green are calculated in 60 fps, and are indicative of standard play:
