performance can be increased by adding a bunch of shit in eqclient.ini. can also delete epics, grass, the sky.
you can even do this:

in later clients.. but not titanium
i don't think this is what changes skeletons into humans, inb4 that. it does in later clients when the skeles got high-poly, but doubt it would here. not personally tested.
i do this when im 12 boxing on ez server. not sure why anyone would want it here because it generally only has the effect of making large races smaller, and various races into humans and therefore slightly harder to differentiate. btw it does not change hitbox or maneuverability in small corridors.
but eh, it reduces cpu load
in general, humans are the default race whenever something goes wrong or gets edited.
just a thought but i would say the aon->human thing is probably a step further than this.. accomplished by deliberately removing the skeleton file. that's a little less kosher imo... ofc no one here it talking about that yet so yeah.. all fyi
also having said all this and subjected your unfortunate soul to reading it, i noticed there is an ogre in the topmost screenshot. so he's probably not deliberately editing files or adding anything
