I'm experiencing very slow performance of spot removal tool on DNG images that I created using built-in HDR merge tool. I didn't try with DNG files without HDR.

Every other file, even the huge 32bit TIFF file, performs more smoothly.

What happens when you turn off the GPU in Preferences->Performance? That makes a huge difference for me with this.

No difference. In fact it seems that this tool is not yet optimized for using GPU:

It isn't indeed but the gnu accelerations slows down develop tools that haven't been optimized. Try using brushes and it will bring even the fastest machines to their knees. Anyway I have noticed that the spot removal is slower on the dogs created from panorama merging or HDR merging than on other files.
