Hi i have the same Problem. When i click on the menu all goes in slowmo and is really ******** to work with.
In Photoshop CC all works fine. I try out every setting. I disable the GPU support, i disable the Open CL etc.
Nothing worked. And Yes, after i change every Setting i start Photoshop new!
this is realy bad work from Adobe, this basic functions and when it goes so on Adobe have problems to explain the high price and the cloud system.
Please understand me right, i love Photoshop and all adobe Programs but this is the reason why i am so frustrating about so simple problems they make.
in the cc2014 my GPU is heating up just when I start the programm. All programms are very slow. I remove all the cc2014 an use only the cc. This is frustrating.
And i have also an Nvidia Quatro 4000 and the newest driver, my Mainbord is an z77 mPower, 16 GB RAM, SSD and an i7 2600K so don´t say my System is too slow for cc2014!
The Graphic card is supported from Adobe so what is the f.... Problem?!
