I am using Photoshop 2014.2.0 20140926.r.236 and I have attached the fill info on the current settings within Photoshop.
I am using Nvidia Titan as video card and the problem occurs whenever I am trying to perform a custom sharpen Photoshop will not respond for several seconds up to 5-10 minutes.
The issue does not occur if I am using the 8bit however it does under 16bits.
I have attempted the following and managed to resolve the hang however it still needs several minutes to process the sharpen.
Please if you can help me resolve this issue that would be great.
I have Win 8.1 and Photoshop CC 2014.2 but don't have that particular Nvidia video card. I tried several 16-bit files and haven't had a problem with Smart Sharpen.
Are these RAW files?
