I've looked online and I've seen a few threads about people complaining about Photoshop Surface Blur being slow.
I'm using a intel I7-3770, 12gb RAM, Geforce 640 video card.
The thing is, when I first receieved the desktop last September and installed cs6, surface blur was very snappy for 8 and 16 bit. Only recently has it seemed to slow down by minutes. 8bit now is still fast now (few seconds), but I still see a lag there I didn't notice before.
I've gone and updated the video driver, changed preferences, tile sizes, etc. Nothing helping.
I just want to experience what I first had...Any suggestions?
