I installed this yesterday and it totally b0rqed my computer. It made me update to DX9.0b from 9.0a and messed up my Omega drivers (Rad 9700 Pro Ult). I lost all textures in Halp and BF. After reinstalling/reconfiguring the video drivers, Halo was still messed up, but BF was fine. I might reinstall Halo tonight if I feel ambitious.
