ICE Programmer Explains Why 4K Gaming May Not Be Possible On PS4, Urges Devs To Use AF In Their Games
OS and video output impose additional limits.
Update: The portion about AF was sarcasm from the developer.
Senior programmer Cort Stratton who is a part of Sony’s ICE Team, has revealed a few interesting tid bits regarding the PlayStation 4 capabilities to support 4K gaming. He was asked whether the next gen console is capable of playing 4K games which are not resource heavy [like Towerfall], he said that the API is capable to do so but the operating system and other factors may post certain restrictions.
“Gfx-API-wise, render targets can be up to ~16K*16K (same HW limit as GL/D3D). OS/video-out may impose additional limits; I dunno.” he tweeted.
Sony never marketed the PlayStation 4 as a 4K capable machine so one may think that they can consider it for games that are not resource intensive. But Stratton stated that there are plans are to support 4K for movies, but not for games.
Stratton also urged developers to use anisotropic texture filtering in their games as he thinks this is the defining feature of next gen. He also revealed that the implementation is similar to D3D and the code is simple.
