Optifine & Shaders on 1.6.4

[nullification]

Here's what I discovered from snooping around the web and such. This will (pretty much) allow you have good graphics while playing on our server. 

Requirements

• Download and install Forge for Minecraft 1.6.4:

Forge 1.6.4 Installer

• Download Optifine 1.6.4 HD D1 from here:

Optifine HD 1.64 D1

• Download this mod and put it in your mods folder:

ShadersModCore v2.2.3

• Download this zip file:

Shaderpacks.zip


Open it, and drag the shaderpacks folder into your .minecraft folder. Overwrite if asked.

Start Minecraft 1.6.4 with Forge.

Go to Options → Shaders and pick SEUS-Ultra-1.7.5.
