The Dying Light PC Performance fix didn't really come with the 1.2.1 patch as many people are still plagued with huge performance issues that won't let them play the game at 60fps or even 30fps, luckily we have a guide that would help you with these issues and would allow you to play the game smoothly.

Youtuber, ZombieNation2012 has uploaded a video where you can use the unofficial performance fix tool aka Dying Light Manager tool to boost your fps in the game.

The Dying Light Manager tool allows you to edit some settings in the game to help you get better performance in the game as well as allowing you to use Dying Light mods on the Nexus. This tool also allows you to remove the film grain and chromatic aberration in the game as well.

It should be noted that Nvidia recommends that you download the latest driver for your Nvidia card as well as updating the GeForce experience to get the best performance out of your GPU and to enable SLI.

To get a ton of FPS quickly, TotalBiscuit recommends that you put the view distance slider to minimum to literally double the frame rate you have right now as he displayed when the max setting of the view distance option cut his framerate in half despite not having almost any noticeable increase in image quality. He also notes that the lowest setting of the view distance still allows you to see enemies from far away so it is safe for you to lower this setting.

Meanwhile, to fix the game only using CPU 1 (thus not allowing all CPU cores to work at its fullest), "Ricin" has shared a method of allowing Dying Light to use all of the cores of your CPU.

"CPU1 is pegged at 100% usage because it is bugged like far cry 4 using 100% CPU3. Simply go to task manager, then to 'set affinity' and disable and renable the core. Presto no more 100% core usage. You will have to do this _every_ game play session." Says Ricin.

The method above would fix the stuttering in the game as well as some issues with SLI.
