Hello @FreedomFaighter, there's multiple games that could be summary called EverQuest, and none of them appear to have a Linux native variant. There's not enough information to start to ponder this feedback.
In general, we're tracking issues with games run with Proton in the Proton issue tracker, and there is feedback on one EverQuest title being tracked at https://github.com/ValveSoftware/Proton/issues/1885.
Please check if the appid matches the game you're playing, and if it does, then please add your feedback to the existing compatibility report, otherwise, open a new compatibility report for the Proton devs to ponder.
Closing as not a Steam client issue.
there is EverQuest and EverQuest 2, others may include the EverQuest name and a list if them is included https://en.m.wikipedia.org/wiki/EverQuest under the Franchise section to help with the Proton database
