I just rebuilt using the ENABLE_THREADS and have gotten more consistent frame rates while loading tiles (thanks for the tip!). I still get some frame rates that are rather low, given my system configuration. Not being a pilot, I am sure that may visibility range is set too high, but I tend to stress my systems.
