You have a laptop. This immediately directs me to instruct you to make sure that Minecraft is using your NVidia card instead of the built-in card. VERY frequently, on laptops, it will use the garbage built-in graphics processor for Java applications, because they rarely need much in the way of graphics.

In addition, the rendering engine was changed in 1.8 to be more efficient (they used to render all blocks down to bedrock, whether the player could see them or not. Now they only render the blocks that can be 'physically seen). 1.7 packs will generally have lower FPS than packs after 1.10.
