I have been able to optimize out another 300Mb. Additionally, the tutorial bug that some folks have been experiencing where the ghost refuses to manifest has been fixed.
See details of the patch below:
· Corrected tutorial bug, where ghosts would stop manifesting and not let player progress.
· After the Camcorder step in the tutorial, the ghost is set to level 3.
· Optimized more UI textures.
· Auto Detect Graphic Settings is more sensitive and will recommend lower settings than previously.
