Low FPS with the Create Mod (And Red Green textures when shaders are off)

What happened?

When shaders are on (We use Complementary V4.3.3) and we are near anything related to the create mod the FPS drops dramatically from sitting at around 60-80 (On an ok Computer) to 5-20 (On the same computer). Sometimes we have to disable the shaders even to make the game playable.

Although when we disable the shaders, all the chests, Create stuff, and stuff that moves look green and red (Shown in Figure 1) When shaders are off our FPS goes back up to 60-150.

What about the red-green textures when the shaders are off? Is there anything we can do about that?
