I have never had any particle effects on either of the computers I run EQ THF on. I was previously doing P99 with the Titanium Edition install disks, and I had spell particles. From the Underfoot install download from THF site, I don't.
I am sure there is either something to switch in one of the ini files, or some switch in the options that I am missing. I have perused eqclient.ini and see several different spell particle effect entries, with numbers attatched. I have not experimented with those yet.
Any help would be appreciated.
