Guerrilla Games has recently unveiled patch 1.14 for Horizon: Forbidden West, targeting visual glitches that appeared in the performance mode on both PS4 and PS5.
Previously, players reported flickering in the PS5 performance mode and similar problems on the PS4 Pro. The new update resolves these issues.

A comparison video released alongside the patch showcases the fidelity mode versus the performance mode, with an added PS4 Pro comparison. The footage clearly shows that the flickering problem has been fixed, giving players who faced it at 60fps performance mode peace of mind.
