My computer is brand new, runs on Windows 10, has 16GB memory etc. When I downloaded the trial version of PS it worked perfectly, now that I've downloaded the full version it lags horribly and keeps freezing when I zoom, rotate or try to change from brush to eraser. It's not the computer, everything else runs fine. And it's not my graphics tablet or driver as I've tried with a mouse and the trackpad. I've been through all the troubleshooting suggestions, uninstalled, reinstalled, turning it off and on again, had nothing else running, designated 75% of the memory usage to PS, made sure it's using the graphics processor and running openCL etc. It's driving me completely mad and I really need it to work smoothly for upcoming deadlines, has anyone had similar issues or might know something I haven't tried yet...? Thanks in advance ... View more
