I recently got pubg, couple of problems with texture loading, got about 50+ hours in the game, haven't crashed or had any problems except for the problems with texture loads
I have an fx-8350 and an rx480 and 8gb of ram I have very minimal problems with pubg running between high and medium. 50 fps averages and the only time I go lower is on spawn island when all my textures are loading. The only real issue I do have with this game is the intermittent disconnecting which is honestly annoying as fuck.
