The Last of Us Part I on PC did not start smoothly. PC players have reported crashes, performance issues, and a host of weird visual glitches. Now, Sony-owned Naughty Dog has started releasing bug fixes to fix some of the widespread issues and investigate other bugs affecting PC players.

A new patch arrived on Steam and the Epic Games Store last night, including corrections for “various performance and stutter-related issues affecting some users.” It’s not clear exactly what was fixed, and for some players it was just a 36MB patch on Steam.

However, Naughty Dog has enabled additional crash diagnostics. It is designed to help the developer investigate crashes related to building shaders and “other common reported stability issues”. The team is closely monitoring player reports and is actively working on a patch with more bug fixes, which will be released soon.

Steam reviews of The Last of Us Part I are still overwhelmingly negative, with more than 60 percent leaving a negative review. PC players have reported random crashes and stutters, long shader compilation times, and numerous visual glitches such as characters getting dripping wet randomly in cutscenes.

Naughty Dog has postponed the release of The Last of Us Part I on PC a few weeks later say it wanted to make sure that The Last of Us Part I PC debut is in the best shape possible.” That obviously didn’t happen, and it’s left many fans wondering if this PC port was rushed out to take advantage of increased game sales following HBO’s well-received The The last of us TV program.
