I could do free banners, profile pics and thumbnails if you would like. I go to school for graphic design so I have the background knowledge on how to make them. I don't make intros though, but any images I can do. PM me if your interested.
when you install optifine, it may be turning on settings through out the game that are too high for you computer. you could try turning off better grass and such, but others than that I would just recommend to not use optifine.
