Hi,

I noticed that each instance of wow is taking around 5gb of ram which seems way too much to me. (using isboxer)
I then ran 5 instances of wow not via isboxer and each one took around 3.8gb of ram. This also seems more than usual, but can't really say.
This is in Ashran, flying above stormshield looking down. I have a macro that changes display settings when swapping windows, so only one instance can actually see something, the rest just see blueish fog. This does nothing to mem usage, it doesn't go down on the instances with lower settings.
Running 64bit version of wow.
