x5 running slow.

[brucet]

I've been testing the trial of x5 now for a few days and have been happy so far. However today it started to run very slow. I'm working with 200meg 16bit tiffs with about 6 layers. (In x4 they work fine). Some files on x5 work fine. But some files run very slow. For instance if I select one layer and go the Hue/Saturation, it takes about 10 seconds for the full dropdown menu to appear. Then each change take 5-6 seconds to regenerate. If I close x5 and restart it. The same files that ran fine will run fine again. Files that ran slow still run slow. Yet they are all about the same size with the same number of layers.

So the question is - is there something I'm missing in the settings? Why the performance difference on files that are almost the same?

I have experienced something similar with large 16 bit TIFFs converted from my Canon RAW but with no use of Layers. (102Mb 5184x3456 pixels)

I find it is intermittent and not always repeatable. Running High Pass Sharpen or Levels can sometimes take 8 or 9 seconds whereas it usually takes 3 or 4 seconds both in X5 and always in X4.
