Durante Announces New Ys IX: Monstrum Nox PC Update; Further Enhanced Performance & Draw Distance

Peter “Durante” Thoman, known for his work on several video game porting projects, has announced a new PC update currently available for the Falcom developed and NIS America published Ys IX: Monstrum Nox.

While he was working on optimizing the Nintendo Switch version of the upcoming The Legend of Heroes: Trails from Zero to consistently hit 60 frames-per-second, he implemented a fix he discovered into Ys IX, which sees enhancements for CPU-limited performance and ultra draw distance.

A graph displaying the improvements of this implementation is viewable below:


Additionally, the following changes were also included in this latest update:

  • Improved CPU-bound performance. The degree to which you will notice this depends on the specific in-game scene, settings, and your hardware GPU/CPU balance.
  • Adjusted the refresh rate selection algorithm to more reliably pick the available refresh rate closest to the one desired.
  • The game executables are now signed. This should hopefully reduce the antivirus false positives that sometimes pop up for some players.
  • Fixed the English item description of the Holy Sword’s Hilt accessory to correctly reflect its capabilities.

You can view the entirety of Ys IX: Monstrum Nox’s PC patch notes via its Steam news page.
