As developer Brendan "PLAYERUNKNOWN" Green explained in an interview, the PLAYERUNKNOWN'S BATTLEGROUNDS team is continuously working to improve the basic structure of the game. In doing so, program routines that fix bugs that have just appeared as "patches" are re-evaluated and the errors are corrected correctly.
PLAYERUNKNOWN'S BATTLEGROUNDS - Tears the plasters off
Such projects normally end in Part 2 of a title, but PLAYERUNKNOWN'S BATTLEGROUNDS is popular enough to justify the mammoth task for the current game. As Green said in the interview, was just that Scalability a problem of the program, nobody expected the millions of players at the beginning of the development. It is not just a matter of going to Mediamarkt and buying 3 new PCs and installing them in the network. Rather, the whole structure and the backend of the game must be designed for this.
Due to the rapid growth, it is no wonder that a quick hotfix often had to be applied, which fixed the current problem, but caused new problems in the long term. Finding these patches and hotfixes that cause problems and repairing them as efficiently and permanently as possible requires a lot of work. So in the end you have hopefully better and more optimized program code, but such changes can cause further bugs on your part. Especially when tinkering around in the depths of the program structure, something like this can have far-reaching effects.
In the long term, however, the PLAYERUNKNOWN'S BATTLEGROUNDS has the plan to almost completely revise the game and thereby achieve a significantly better performance. Because in contrast to competitor Fortnite, PUBG is quite a resource hog, at least for the moment. It remains to be seen how far the code can be optimized. Because the time of extreme growth is over and PUBG is moving at a constant level, so there is finally time for optimizations.
