PUBG players will definitely want to grab the game’s latest patch, as the team has made tweaks to diminish some major issues that include intermittent lag and character position readjustment. It sounds like the developers have a lot of work ahead of them in terms of eliminating the problems entirely, however.
In this patch, we have removed some inefficiencies in server infrastructure and optimized in-game servers to alleviate the problem. More specifically, we made adjustments to reduce the bottleneck during the game server launch phase and also resolved some server hitch issues. Resolving the intermittent lag and character position readjustment issues are still one of our top priorities, and we are continuing to work on analyzing and fixing any remaining issues every day.
