Horizon Forbidden West Update 1.13 vs. 1.15 Comparison: Performance Mode Finally Fixed

Guerrilla Games has released Horizon Forbidden West update 1.15 recently for PS4 and PS5 which has resolved the performance mode visuals.

A lot of players had reported that there was shimmering with the performance mode enabled on the PS5. This was also present in the PS4 Pro version of the game. It has been resolved now with the launch of the new patch.

The video comparison above goes through the Fidelity, and Performance mode for the game in addition to the PS4 Pro version. It shows that the shimmering is practically eliminated now so if you were facing issues with it in the Performance mode that runs at 60 FPS, that should be gone now.

There is no change in the resolution of any of the graphics modes but the way the game was rendered in the performance mode was prone to a lot of shimmering around the edges. For a game with a lot of foliage like Horizon, this proved to be problematic.

If you want to learn more about the changes in the new update, take a look at the patch notes below.
