I am now around 25% through the game and holy frigamoly, running an RTX 4090 with everything
completely maxed on a 4k OLED it is probably overall the best looking games I have ever seen. It's insane that Rockstar managed to release a game like this in 2018 and over 4 years later it is still one of the best looking and most detailed games in existence. The character models are the only thing that do not look close to photorealistic... almost everything else, especially the scenery, could easily be mistaken by many people for a real photo. You can see so far into the distance too and combined with the volumetric light/smoke/mist and water effects it is jaw-dropping.
If there was ever a reason to buy a high end GPU that costs silly money, it is to play games like this and CP2077 fully maxed out. It is a phenomenal achievement, a masterpiece of a game that oozes atmosphere from every pore and is clearly a labour of development love. I'm going to play through the main story, deviate a bit and not spend silly amounts of time being a completionist. It will still take me a while and be worth every minute.
