Something I just checked. I'm running Resynthesizer, normally a huge CPU intensive operation. I decided to see how the new setting affects GIMP and I'm amazed. GIMP is using 0% CPU cycles and Resynthesizer is only using 14% (trust me; it went to 50% before I enabled this setting). Pretty stoked I am. So much faster, but, they can, I believe, make it even faster then this so I'm looking forward to 2.10x release to see how fast they can get GPU acceleration. I only can tell you that PS GPU filters are like near instantaneous. It would be cool to see Resynthesizer run instantaneously; just my dream.
