That seems to have done the trick, thanks very much.

Hi, I'm currently playing single player with the Tekkit pack. Why you may ask? I started playing it on a server with a friend until he decided he didn't want to play anymore, so I just put it into single player as I didn't know about compatibility issues with Technic and Tekkit. Anyway.. I have a small house with a load of machines, nuclear reactor next to it, some solar panels etc. So basically, most things that would use up my CPU usage are in my house. I have 2 quarries and 1 pump outside my house, around 20 blocks away. When I am in or just close to my house, I get around 20 FPS which I'm happy with overall. I run low settings as my laptop is not designed for heavy gaming. Now, the weird bit.. when I walk any further than around 10-15 blocks away from my house my FPS drop to around 2. I can't see any logical explanation for this at all. Here are my specs: Windows 7 Home Premium 64 bit 4GB DDR3 RAM Running Java 7 If anyone has any clue what is causing this, I'll be happy to try pretty much anything. Before it never used to do this, it's just recently. Yes, I am on the latest version of Tekkit and the launcher.

What are your video option? What processor do you have? How much RAM is allocated to minecraft? What graphics card do you have? When playing, what is your FPS? We need this information.
