ATi Radeon HD4650 is a quiet OLD card - i doubt that you will be lucky with PUBG on that GPU
btw - you CANT use latest driver with that GPU - its NO-GCN
and i think you cant use the Non-GCN 16.2.1 Beta Driver - this driver is compatible for HD5000 and newer
latest driver i found that is compatible is 13.4 Beta
you should invest in a RX580 4G (can be found for around 130$)
