I've recently upgraded to PS CC and wanted to try out the new Smart Sharpen filter. I'm using Win 8 Pro with an Itel i7 core processor and 16GB of RAM with 14 GB dedicated to PS. GeForce GTX 650 video card with another GB of RAM there too. Tons of internal scratch disk space on a solid state hard drive with a 750W power supply. In short, until this upgrade, my computer yawned at everything I asked Photoshop to do. Now, when I use Smart Sharpen I'm delayed both when I apply and turn off.
This is the only delay I've seen so far but just really starting to roam. Any ideas for me to try? Would increasing the cache in performance preferences help?
