Frequent FPS spikes when turning.

[Bumagan]

Hey everyone. I've been having frequent FPS drops when turning. My screen will freeze for about .25 to .5 seconds before immediately clipping to where my turn would have been had my screen not frozen, which is very disorienting (particularly when trying to follow people).

It seems to only happen when I'm turning, which is very strange.

I am running on Windows 11 with single core affinity. Are there any other tricks I should do to try to improve performance, or is this just how EverQuest runs? (I tried running in Windows XP SP3 compatibility mode but had the same issue)
