Gaming Minecraft: FML not working with Optifine in 1.5.2

[Mr.x2011]

Hey GBATemp,

Recently I have installed Minecraft 1.5.2... I have also installed Optifine to help it run with a higher fps rate and Forge ModLoader but it seems these two mods, which are some of the most well known, do not work together... does anyone know why they don't work together and how it may be possible to fix this (i.e a certain version of Optifine or FML)..

Thanks in Advance,

Mr.x

Edit: It turns out that FML doesn't work with Optifine Ultra but it WILL work with Optifine Standard.
