Horizon Forbidden West has a strange HDR bug on PS5

techradar.com:

Horizon Forbidden West is a sumptuous-looking game on PS5, but it’s currently plagued by a number of distracting visual issues, including a strange HDR bug that causes brightness to fluctuate whenever you move the camera. 

The issue has been analyzed by Vincent Teoh of HDTVTest, who used a Canon reference monitor that includes a real-time video data waveform analysis tool to show what’s going on. 

As you can see in the video below, Horizon Forbidden West’s HDR compresses every time the camera moves and then returns to normal once the camera is static. This results in a clear shift in brightness, causing a noticeable flickering effect. 

The issue occurs in both Resolution and Performance modes and is more noticeable in Horizon Forbidden West’s lower frame rate mode. If this HDR bug is too distracting for you, we’d recommend turning off HDR for now until Guerrilla Games releases a fix.

Unfortunately, Horizon Forbidden West also suffers from more visual problems outside of its HDR mode. As Teoh and many players have pointed out, the game has issues in Performance mode such as aliasing artefacts, shimmering, and noise on foliage, as well as pop-in. 

Resolution mode isn’t perfect either, as this mode appears to include some artificial sharpening that makes the game look noisier than it should. There’s also the fact you're confined to playing at 30fps, which some players just can't stomach in 2022.

Guerrilla Games has recently released patch 1.05 which addresses numerous gameplay issues as well as crashes, but the developer notes that the team is looking into “several graphical issues reported by players regarding shimmering, sharpening and screen saturation when moving the camera” as a high priority. 

While there’s no denying that
