Okay, so its my terrible Graphics card
because my RAM is 1GB
Don't listen to Zackin, hes stupid. If he doesn't know correct info, he shouldn't post. A graphics card would help, but RAM is a much cheaper solution to higher FPS (in Minecraft at least). I used to have 1GB of RAM and integrated graphics, but I recently bought an extra 2GB of RAM and now I can run Minecraft at about 35FPS average. The reason of this is because Minecraft doesn't require graphics at all, it will barely help to get a graphics card. You are rendering thousands of blocks as you walk, which can get heavy on your RAM and processor. A better processor would help too.
