Dying light 2 conflicts with Alienware's AlienFX lighting. It makes some Alienware products that have lighting on it, to flash / blink constantly, making it really hard on the eyes.
This is the only software I've ever experienced this issue with. This was also reported many times on steam forums, and the only workaround is to stop AWCC.Background.Server process before running the game, or fully turning off any Alienware lights if the hardware has the option to do so (for example, my monitor has this option in its built-in firmware) - this later one may not even work, as sometimes the game just forces the links on again and makes them blink and flash.
Also, turning off ASUS' aura sync compatibility in the game, does not solve the issue. Plus, the flashing persists even after fully closing Dying Light 2.
