After skimming through the threads I've come to to the realization that most of the problems you're mentioning are due to the fact that people are, of course, trying to run it on Vista. Given Vista's downright lousy compatibility layer it's no wonder they're having problems. And no wonder I haven't experienced any. I still use XP.
The Vista problems have more to do with Troika not being able to support the game properly. Had Activision let them do their jobs and polish the game, I have no doubt that it would run fine under Vista. The Source engine runs great on Vista, as do many other games. Bloodlines uses a pre-release version of the Source engine.
After some research, there are some tweaks to getting the game to work under Vista properly. There is a Vista thread in the Steam Bloodlines forums detailing the procedure, but I will summarize.
To get the game to launch in Vista without memory errors in Vista 64 and 4GB of RAM, there are some executables in the unofficial patch that patch the engine.dll file to allow it to run.
To get the game to run in Vista 64 without ultra blurry textures, there is a tweak that can be done to another DLL file involving hex editing. Another individual has posted a link to a pre-edited DLL that can be used.
Lastly, the unofficial patches also include a resolution tweaker to get the game running in wide screen resolutions.
