As the description says for some reason per pixel doesn\'t work in 64 bit mode. Does work in 32 bit mode just fine. (To enable right click on d2x-xl.app and select \"get info\" then check \"Open in 32 bit mode\" if anyone wants to try that)
when in 64 what displays is part of the render and the rest is black. If you move the other half appears and the first half goes black.
