There's nothing you can do i'm afraid, unless it changes in the next mod updates, optifine and forge aren't compatible :/

Thank you for the Idea! Now Forge is Compatable with Optifine, and Modloader!
Please download the latest version of our Forge! Please go to our website:

Any Shaderpack mod will work now even if you have Forge installed.
If you have an older forge, please renew it to the new Universal version.
it will contain FML (Forgemodloader), Forge, and Minecraft Coder Pack.
Those will be all the things that will allow you to upload Modloader and Optifine mods into minecraft!


Please do NOT upload Modloader or Optifine if FML and MCP is in the mods section in your minecraft game.

FML and MCP will allow you to use Modloader and Optifine mods.

Thank you for the idea (even though it wasn't an idea xD) and enjoy our new Forge!
