I have made some observations: There is a memory leak that persists even if you change zones, which seems to require a full logout and login to resolve. It becomes noticeable after about 10 hours of play. Disk I/O is by far the biggest cause of CPU wait for my computer. It is regularly hitting 100% during play, not just during scene loads, meaning that perhaps the game should have an even bigger memory footprint? I'm going to try moving my sota install to a pcie ramdisk to see how the game really performs.
