Sorry Rudd. Ok... and I just asked my friend how to get rid of them.
"You must first have to try downgrading the Texture settings in PR. IF that doesn't work set them back to normal settings. Next, you have to downgrade CCC to 11.3

That should be good for you. But I did have these problems with my dinosaur computer when PR first came out.
NOW, if that doesn't work. You MIGHT need to get a new computer, I can't see much. But It also COULD be your processor. If it's pretty old or very dusty... You should clean it every 2 years. Just use a vacum but don't bang on any parts."
Don't be a noob, don't be a jerk.
Be a MAN.
