Broken Lighting, Shadows. Purple, Blue, Red Shading

[𝓢𝓲𝓵𝓵𝔂𝓕𝓸𝔁]

I haven't seen anyone having this issue for decades, been trying to find solution to fix it, but found nothing. I'm the only one experiencing this problem

The game renders badly in the darkness when you are in the darkness even in most darker areas. Not the one with the flashlight problem, cause it works perfectly fine.

When i'm in the apartment corridors. They don't render a proper shadows and the lighting are messed up, sometimes each every rooms gets mixed with some purple, blue, red, yellow shadow effects. I experienced this bug since the day i played it since 2013, so then i came back to finish it as of today. Still having this issue. Although usually in dark places, it gets fullbright so it becomes unplayable but feels like cheating with this bug.

I don't know if the opengl is the cause of this, but i've only downloaded the game

Very interesting... I have never heard of this bug in CoF. Have you tried reinstalling the game maybe? Or at least validating the game files?

I have this issue as well, but it only started happening when I got in the woods and mental hospital, with purple, yellow, blue shading affects like you described.

Turns out it was the brightness and contrast turned high. It makes sense, strange.
