What can I do to increase PUBG FPS?

Upgrade computer hardware
Graphics card is the most important part of hardware for increasing FPS. Minimum graphics card for PUBG to get stable 60+FPS is: gtx 1060 6G. CPU is the second important part, upgrade it if it is under i5. Then is the memory, upgrade it to at lease 8G DDR4.
Graphics settings(For Nvidia GPU)
Right-click your desktop, click "Nvidia control panel". On the popped up window, find "Manage 3d Settings" on the left side menu bar and click it. Then, on the right side, find "Multi-display/ Mixed-GPU acceleration" section, change it's setting to "Multiple display performance". Find "Power management mod", set it to "Prefer maximum performance". Find "Texture filtering", set it to "Performance". You can get 10 - 15 FPS increase by doing this.
In-game settings
Go to in-game graphics settings adjust the quality to lower level. For example, lower or turn off Shadow, Anti-aliasing, Post processing. You can get 12 - 18 FPS increase by lower the video quality.

Note

Take a look of your monitor specs. If it is a 60HZ monitor, the maximum FPS you can possibly get is 60 whatever how good is your graphics card. If it is a 144HZ monitor, the maximum FPS is 144.
