After downloading the patch on PS4 to "improve graphics" it has caused some terrible textures in the game that wasn't there before. This is just one example of the many found after the patch.
The Retouched update for Dying Light that improves graphical features has been released; here's how it compares with the Enhanced Edition.
I remember playing this for the first time on the PS4 and it knocking me sick and hurting my eyes due to the horrible motion blur and FPS.
Played it a lot on pc a year later. Then again on ps5 once they dropped the 60fps update. I'll be giving it another go. Mad how they have kept updating this game for 10 years.

Hey Survivors! Tymon here, your favorite Dying Light Franchise Director.
It's been an absolutely wild month here at Techland! We're in the thick of what I'm calling the "Summer of Dying Light," delivering updates and big news across all three Dying Light games. Just a few weeks ago, we dropped the first gameplay for Dying Light: The Beast, revealed its release date, and kicked off pre-orders (if you haven't seen it, check out my last dev blog). I'm incredibly proud of what we're building with The Beast - it’s the culmination of more than 10 years of experience in open-world survival horror!
But here's the thing: we never forget where we came from. That's why, this week, we're not just looking forward - we're rolling out significant updates for both the original Dying Light and Dying Light 2: Stay Human. We promised to support our games for a long time, and we're committed to continuing that support, right through and beyond the launch of Dying Light: The Beast.

It has been more than ten years since Dying Light was released, but what happened to the $386,000 'My Apocalypse Edition' of the game?
Wtf did this edition come with ? A real helicopter and a real zombie virus ?
So one graphical glitch equals news? This is nothing new. Texture and shading issues are common in games, especially those that are open world/sandbox.

Yes these types of glitches are common, whether or not someone believes it is irrelevant.
Dying Light had texture issues on the PS4 before the patch...

this SAME glitch happens to me in real life when I take my glasses off.
Ps4 needs to be 720p really to run these games smoothly
lol this have to be lamest articles I have seen so far, every darn game has glitches after or before a patch, this video example of is totally insignificant.
