Hi,
I'm in trouble with the new Adobe Photoshop CC. I got 4 PC workstations with windows 7 SP1, SSD drive, bi-xeon E5-2630 64 Go ram, Geforce GTX 780 with the last driver 320.49.
We use the performance default settings :
The graphic card is detected by photoshop
"use graphics processor" is checked
"drawing mode" = advanced
But the paint tools is lagging horribly. We prefer use our old stations (3 years old) with photosop CS5 which are completely smooth with the same brush and the same picture size (2048x2048, nothing crazy)
I did the 14.1.1 update but nothing change.
So, what we can do ??
