What you see above is a 4K shot of the PC version of GTA IV with some mods applied. The author of this impressive work is Raphael Smith who has explained how he did it:
“I have a Steam version of GTA IV which I modded with Better City Textures, GTA IV Road Textures by Fonias, Supreme Vehicle Conversion Pack-140 vehicles, Traffic Control System V1.0B, DKTronics70 Vegetation, and a first-person mod by C06alt. Then used IcEnhancers beta 1.25 ENB for the lighting.”
