I just found out that Arthur’s pupils actually dilate and constrict based on the light levels. The level of detail in this game is bordering on insanity. 👁️

I was messing around in Photo Mode near a campfire at night, and I noticed that when Arthur looks at the fire, his pupils shrink, and when he looks away into the dark, they expand in real-time.

Rockstar really spent time coding physiological eye reactions that 99% of players will never even notice. It’s been years, and I’m still finding new things.

What’s the smallest, most "unnecessary" detail you’ve found that blew your mind?
