I recently bought minecraft for my laptop running windows 7. It runs very slowly and laggy to the point where it hurts my eyes to even watch it. I changed the settings to turn off clouds, reduce FPS, fast graphics (not fancy), turned off textures and turned down some other settings. I have even given minecraft high priority use of RAM. My laptop is a year and a half old with a second generation i5 processor, 6 GB of RAM and I make sure I have no other programs running. It is a Dell inpspiron.
Any idea of why this runs so awful? Think it would run better on my MacBook Pro? How can I speed this up?
