Up until just a few days ago i could run minecraft at 90-130 fps just fine and smoothly with normal render distance and fancy graphics. then it just started randomly going from a smooth 90-130 fps to 1-50 fps at random or whenever i hit a block or was just walking around my world. This made me think my survival world was corrupt but no other world works right either. Every other game on my computer runs just fine with all high settings and have tried force updating and optifine but still no change. Could someone please help because i really want to get back to playing minecraft without problems.

CPU: Intel Core Duo E8400

One option is to install OptiFine so you have more options for your video settings. However, the easiest thing to do is just set all of your video settings to things like "Max FPS", "Fast Graphics", etc.

However, you could also try and add more memory to Minecraft via CommandPrompt.
