Ubisoft hard at work on further AC Unity performance tweaks

Previously on the Assassin's Creed Unity glitchfest saga.

After much hype and excitement, Assassin's Creed Unity launched to mixed reviews and widespread complaints about performance issues and bugs. Ubisoft introduced some fixes with Patch 2, but the complaints raged on. Will the game be playable before everyone finishes the single-player campaign?

And now on the Assassin's Creed Unity glitchfest saga.

Ubisoft has detailed a new round of performance tweaks that may land in the next update, Patch 3. The company says there's a "distinct discrepancy" between the performance it observed before and after the launch, and it chalks up the problem to the game's instruction queue, which is apparently "becoming overloaded." Here's what Ubisoft plans to do about this:

  • Streamlining some technical aspects of navigation: We've fixed a number of edge cases with our detection system to smooth certain behaviors during parkour. We've fixed a few objects which were improperly tagged to smooth navigation.
  • Improving task scheduling: We've tuned the way the computing tasks are prioritized and parallelized by the processor cores to improve framerate in certain edge cases.
  • Tweaking performance for Reach High Points: We've optimized the reach high points, during the camera swooping sequence to improve framerate a little bit.

The company adds that it's not going to tinker with the number of non-playable characters on screen. Crowd sizes are "not linked to this problem," Ubisoft says, and reducing them "does not improve [the] frame rate."

When can we look forward to Patch 3? Soon. Or maybe not so soon. "We're working very hard to see these changes rolled out in Patch 3," Ubisoft says, "but as we're still testing our fixes we need to be conservative with any estimates as far as ETA is concerned."

Oh well. There's always Far Cry 4... which is another Ubisoft game. Damn you, Ubisoft!
