Of course, I never saw it on big screen, but it looked good on my computer. :') I was able to successfully composite together a 2k film res animation that had many layers for a movie company logo and the FXtree worked wonderfully.

The size of the PIC file in disk, if that's what you mean, has no meaning, since it's a compressed format and must be decompressed. But the .Zpic is uncompressed. So if that one is 64 meg, and since the ZPic is only one channel, it tells me the the DOF is going to need a temporary buffer of 64x4 = 256 Megs of RAM. That's a huge freaking amount of RAM, and it's only for the temporary buffer in the DOF effect. So you may be saying you're compositing a single image, those images you're working with are unusually big. The FxTree isn't really thought to work on images large than 2000 pixels. To handle very large images in 32-bit, software like Shake cut the image in tiles but the Fx Tree doesn't do this, it focuses on compositing images rapidly for video and HD, not IMAX.
