How to reduce tekkit lag.

Question

I love playing tekkit and it used to work like a dream.  Now it lags when ever i am close to my house.  I understand that the more stuff I have in my tekkit world the more it will lag but this is hardly playable.  If anyone has any idea how to make it faster, I would greatly appreciate it :D.

I'm afraid that the most likely cause is that your PC just isn't up to it in terms of RAM. For a temporary solution, you can try allocating more memory and lowering your render distance, which is not ideal. Also, if you haven't already turned off clouds this might be an idea.
