High input lag on new workstations

[jwwatts]

Upgraded company workstations.  Able to connect from newer or older hardware to older hardware running NX without issue.  However when connecting to newer Dell 3680 machines, input lag on login screen as well in the remote session is about 10-20 seconds.  Applies to mouse as well as keyboard events.  Remote machine’s nxnode.bin process pegs one CPU at 100% while the input is lagging.

Older hardware is a Dell Precision 3650 w/ i9-11900K, OS is CentOS 8 stream running kernel-4.18.0-348.7.1.el8_5.x86_64

Newer hardware is a Dell Precision 3680 w/ i9-14900K, OS is CentOS 8 stream running kernel-4.18.0-553.6.1.el8.x86_64

Tested NX versions are nomachine-7.9.2-1.x86_64 and nomachine-8.14.2-1.x86_64 (problem exists with both)

I’ve sent in the server logs from the 3680 workstation that’s affected.  Thanks for any help.
