Mercury playback engine gpu acceleration greyed out
I have the brand new macbook pro max fully upgraded. My project for some reason recently has just been super laggy. ill open it up & then when i skim through the timeline all of a sudden the playback will freeze. I have all other funcitons in premeire but the playback on the computer wont work. Im trying to see if i can change the Render & Playback settings but its greyed out i cant figure out why. Ive tried opening a new project but its the same thing.
