My current issue is that when I use certain effect presets, I get the "This effect requires GPU acceleration" message and I have it enabled. It is on the recommeneded setting and I have tried switching to the other GPU setting. Is it Premiere or is it my computer because I've tried everything I could think of to make it work. For added context, I have a mid 2014 model MacBook Pro with an Intel Iris Pro 1536 MB graphics card.
when Premiere pro does not work the way it should I generally reset the Premiere pro preferences as follow -
Press Alt (Windows) or Option (Mac OS) while launching Premiere Pro. You can release the Alt key or Option key when the splash screen appears. To reset preferences and plug-in cache at the same time, hold down Shift-Alt (Windows) or Shift-Option (Mac OS) while the application is starting. Release the Shift-Alt keys or Shift-Option keys when the splash screen appears.
