Ive recently bought a Dell Inspiron 15 model 4k with an AMD Radeon R7 M270 GPU and it was mostly for adobe suite usage. But ive been having a lot of lag and sluggishnes Using Photoshop CC 2015 or even last years version wich i tried already. does anyone have any idea of whats going with it? Im pretty sure this unit is capable of alot more
Its probably using the integrated GPU (likely Intel HD 5000 or similar). Configure switchable graphics to use the AMD for Photoshop CC and you will have a rocket for editing.
