32-bit application issue:
The first beta is a 32-bit application. I have to be a bit technical to explain the implications:
A 32-bit application runs on 32-bit and 64-bit systems without issue but with limitations. If you are running Oloneo PhotoEngine on a 64-bit system with, say, 8GB of RAM, PhotoEngine will "see" and use only 2GB of RAM because it is a 32-bit application.
If you are working with high resolution files (greater than 16Mpix), such as Canon 5D Mk II Raws, you will hit pretty quickly the 2GB limit. Remember that Oloneo PhotoEngine is a true 96-bit per pixel, wide gamut and high dynamic software. In such an environment, assembling multiple high resolution Raws requires quite a bit of memory.
