If Player List Plus is enabled, do disable it and see how it runs.

If the problems persist, try enabling the ‘Small Network Packets’ option within the ‘Network’ panel. As Smoker mentioned above, it’s important that Player List Plus remains disabled whilst this option is enabled.

Are you running DX11 or DX12?

If you are running DX11 switch to DX12 and see if the issue persists.

Do report back if it works!

Some setups seem to have the latency issues you describe after a patch this spring / christmas (I took a hiatus but when I started playing in April again DX11 was a mess for me but DX12 worked splendidly).
