Since the Photoshop CC 2017 update, I have noticed that the latency of tools, menus, and the cursor increases the longer Photoshop is open.
It lags to the point where I can't even work at all.
I have also tried CTRL ALT at startup and re-arranged the scratch disk order, but again, this hasn't helped. I am running: Windows 10 Home 64-Bit Intel Core i7 3.4GHz Sandy Bridge CPU16GB Dual-Channel DDR3 RAM2GB Nvidia Ge Force GTX 570 GPUAsus Sabertooth V2 Motherboard I am also using Photoshop for image retouching. I have even tried changing the font options and disabling the rulers, as suggested when this happened in the 2015 version of Photoshop. Your comment on the scratch disks using ctrl alt reminded me so I tried that.
There are only 4 choices there, but my missing drives (in PS) showed as available, so I chose one of those.
