Using an eGPU with Observatory?
« on: April 01, 2019, 01:35:44 PM »
Has anyone tried running Observatory using an eGPU? If so, does it make a noticeable difference in image/stack processing time?

I didn't. I doubt right now it will make a big difference though because the current bottlenecks in the image processing pipeline are disk I/O and some parts that are still running on the CPU. Observatory uses OpenCL internally and I think you may start seeing a difference when it gets support for Metal, because that is also when I intend to remove some of the current inefficiencies that occur when applying multiple adjustments to an image (a left-over from the time one could apply the adjustments in any order).
