Since 1.9 lag is unbearable, I decided to go back to the version of Minecraft that I first started playing which is 1.3.1. I've been wanting to install Optifine so I can run my texture pack without using MCPatcher. I tried going to the 1.3.1 jar that is located in the versions older in the .minecraft folder and installing it the old way; dragging the files from Optifine on to the 1.3.1 jar and deleting the META-INF folder. I did this, relaunched Minecraft and Optifine is still not installed.
I'm not really a computer genius and this probably has an easy fix but what exactly am I doing wrong? Is it possible to install mods on older versions with this new launcher?
