Rockstar has released a patch for the PC version of GTA V. Patch 335.1 is meant to fix some of the bugs and glitches that have troubled the PC game since its release last week.
Notable changes include fixing a glitch with the Humane Labs Heist where players could get trapped in the clouds, fixing a character transfer glitch, fixing a bug that allowed players to buy more vehicles than they could store, fixing several problems with the Rockstar Editor, moving the Steam overlay, and making Windows Media Foundation required instead of Windows Media Player. You can find the full list of changes in the official patch notes.
Some players are reporting performance issues after downloading the patch. This may be a problem with the Steam overlay, so try disabling it if you notice your game running slowly.
Patch 335.1 makes important changes, but GTA V PC still has some problems. Many players have encountered a glitch with the Fleeca Job heist mission that prevents them from completing challenges, and a few different actions cause the game to crash. Future patches should solve these issues.
