I am trying to use the latest tutorial about Perpective Warp. I have done the most recent download update today but when I go to edit, the Perspective Warp option is grayed out.
Photoshop grays thing out when some condition does not allow it to be use. The condition could be related to the current state of the active document, or related to hardware and software. Like Perspective Warp requires a GPU and may also require some amount of VRAM. Photoshop CC requirements state Video Adapter with GPU and at least 512MB VRAM. Check you Photoshop Preferences.
Photoshop menu Edit>Preferences>Performance GPU must be seen and enabled.
thanks...I have had this GPU problem with software plugins such as NIK and OnOne. Nik techs have given me workarounds so that software works but slowly....even tho I have 8 Gs of ram, I think that my graphic card is not powerful enough for CC.
