If you're playing The Last of Us Remastered you possibly noticed that the game suffers from pop-in issues in certain areas. Basically when you walk close to some elements of the environment they just "pop" into view. Other items "fade" into view and more flicker between being visible and invisible. All those glitches, while minor, can be a little disturbing. Naughty Dog programmer Corrinne Yu, which is well known for being an industry-wide expert in graphics engineering, gave an in-depth explanation also explaining how she learned more about the PS4 GPU and promising to do better, also inspired by all the pictures sent by fans.
