I temporarily disabled OS by renaming the d3d9.dll and this HAC works fine except I didn't get any boost on the game loading time (still about 5 mins.) Map downloading is awesome, fast and easy and seeing maps like Sanctuary without flickering bsp is nice.

However I was missing active camo fix and HUD scaling (doesn't work on my build of OS even half the time though). If you manage to make this work with OS I love you! Glad you stepped out from the bungie.net forums, Btcc22.
