Gallium Nine utilization inconsistency

[rea987]

For unknown reason, Gallium Nine isn't always utilized when I launch a Direct3D 9 game.

As I have just tried with Warhammer 40,000: Dawn of War - Winter Assault, Gallium Nine wasn't utilized in some cases for no reason. As Steam Overlay doesn't function while Gallium Nine is active at the moment, it is quite easy to detect whether Gallium Nine is active or not. This also happened with Deus Ex, Path of Exile and Dungeon Defenders II that indicates a general problem rather than game specific issue.
