A tip for those with lagging graphics or high gpu load
There is a Microsoft project called D3D9on12 that allows you to map directx 9 calls to use directx 12 this is an opt in driver.
https://github.com/narzoul/ForceD3D9On12This project forces applications to use the mapping library.
Just download the release and drop the d3d9.dll into the everquest folder,
For me all graphics lag is gone, no measurable gpu load each client is 0% in taskmanager, it uses an extra 100mb of ram for me but the complete lack of stuttering makes it more than worth it
