After many hours of browsing the source and the Changesets I finally found the cause of the huge FPS drops and is this line of code:

Code:

4554         -     // No need to reload or check the texture cache if no texture parameter
    4552     +     if (display.isGeAddress(context.texture_base_pointer[0])) {
    4553     +     textureChanged = true;
    4554     +     // wait for rendering completion when using the current GE as a texture...
    4555     +     re.waitForRenderingCompletion();
    4556     +     }
    4557     +     
    4558     +     // No need to reload or check the texture cache if no texture parameter

Doesn't the option "Enable saving GE screen to Textures instead of Memory" help for such cases?
