That's an extremely large atlas. Is this with no modifications to the rev?
I may go back to straight replacepixels with the image cache logic in place to see if that does anything. The alternative is to create multiple atlases, which makes things that much more painful.

[mewmew]

Yeah, on rev c51e464 with no modifications (except for fmt.Println and update to config.json to locate MPQ files).
