The lag during game play could be caused by various reasons.
1) Improve network settings
If the network you're on is via a router, splitter, wi-fi or mobile phone tethering, lags may occur.
If you're using a router, try updating to latest firmware.
Some routers may require DMZ settings for smooth gaming experiences.
Please check if it's any better after DMZ setting is complete.
Also, updating the lan card driver could improve the performance.
- Control panel -> Device manager
(If you can't see the Device manager, click on 'See in classic mode')
- Select the network adapter and check the name
- Double click on the network driver
- Select the Driver tab and check the date of the driver
- If it is not the latest version, update the driver
The Windows firewall could be blocking the game.
Control panel -> Windows firewall -> Click 'Restore default'
Security software that are installed on your PC could be interfering the game.
From the security software, set PUBG as an exception. If it is already set as exception, stop real-time protection and run the game.
PC infected by a malicious code could cause the lag.
Open Task manager(Ctrl + shift + ESC) and see if there are any unusual processes running.
You can search to find out if the process that are running is normal.
