Naughty Dog has issued a hotfix for The Last of Us Part 1. It aims to fix the numerous problems faced by PC players, such as long shader compilation times, a potential memory leak and buggy character interactions. https://www.notebookcheck.net/The-Last-of-Us-Part-1-v1-0-1-6-Patch-deployed-to-address-PC-performance-issues.704669.0.html
I think it's common practice now to push a game out of the door prematurely to meet the initial pre-order demand and then fix it later for another "finally fixed it you should play it now" sales demand.
Welcome to era of digital distribution..
Still, there are a lot of monkeys making preorders.. Until people start to learn on their mistakes, such releases will be a norm.
