Ubisoft continues to work hard on fixing all of Assassin's Creed Unity bugs, glitches, among other issues. With the frame-rate issues still unsolved,Ubisoft has stated that crowd sizes aren't responsible for this.
"We've received a lot of feedback on the performance of ACU over the past week and we're taking it very seriously. We know this is a very important issue to you and we want to see it resolved as much as you do," said Ubisoft.
"We have just finished a new round of tests on crowd size but have found it is not linked to this problem and does not improve frame rate, so we will be leaving crowds as they are. It's taken us some time to make progress on this front, but we've got some promising findings to share.
"We can tell you that we have detected a distinct discrepancy between what we observed in the pre-launch versus post-launch environment. In spite of our testing, it looks like the instruction queue is becoming overloaded and impacting performance."
Although there isn't yet a definite fix, Ubisoft states that the team is currently working on a few fixes that should improve the framerate stability for all players.
