Horizon Zero Dawn PC update includes performance improvements

Guerrilla Games has released another update for the PC version of Horizon Zero Dawn that focuses on performance and bug fixes.

According to the official patch notes, this update fixes RenderTarget aliasing, which reduces VRAM usage and “may improve performance, texture quality, and model quality.” There’s also an improvement for automatic shader optimization that should make the optimization step message appear less frequently on mid-high spec machines.

In addition to the above improvements, a number of graphical issues have been addressed, including HDR looking washed out, graphical glitches, fog being turned off with shadows, and plant simulation issues above 30 FPS. Read the full patch notes below:
