Laggy minecraft

[zukodark]

My minecraft is really lagging in the MENY! In the texture pack select, ingame when I have fast and tiny... The same with tekkit vanilla... But tekkit is not lagging at all with normal render and most settings at far...

Install optifine. It helps a lot.

It began when I installed optifine. I have uninstall optifine and everything, still lag.
Normaly I have no lag when playing with fancy and far.

Try deleting your .minecraft/bin/ folder (NOT the entire .minecraft folder), and logging in again.
You may simply have a bad install/old libraries.

Still takes 15 seconds for minecraft to just know I have the cursor on Singleplayer button...
