Check this out. Several fine gentlemen of the most respectable kind are working on porting Bloodlines to the current version of the Source engine. If they succeed in their noble undertaking, the perfomance issues that are blighting VtM: B will finally be solved. A lot of progress has been made, and some maps can even be compiled in Hammer. You can find the instructions here. As a bonus, the port will be much easier to mod and expand than the current version of the game; one of the first attempts can be found here. The parallax mapped Giovanni mansion looks incredible.
