GTA V's 1.09 patch significantly improves the frame rate on the PlayStation 4 version, but removes parallax occlusion mapping from both the PS4 and Xbox One versions. This is the technique that makes flat textures appear to pop out. More after the jump.
Eurogamer breaks down Digital Foundry's findings with a frame rate comparison that shows a steadier frame rate in GTA V's busier downtown sections. Collision physics and deformation also have been improved with the patch. They highlight that the missing parallax occlusion mapping will mainly affect those who play in first person mode, as they view the textures at a much closer proximity. Digital Foundry also question the graphical technique's removal from the Xbox One version, where frame rate has not seen an improvement.
