Graphics glitches

[Lehiff]

I recently re-installed Bloodlines after a lengthy gaming hiatus, because I wanted to try out Wesp's newest patches (the ones I've tried before are excellent, btw). Since my last time through Bloodlines, I've upgraded my computer with a new graphics card and a lot of RAM. That's supposed to be a *good* thing when you want to run games, right? And in the case of most games, it is. But Bloodlines keep throwing up weird graphics glitches; they're not game-destroying but they are damaging the whole gaming experience.
Some examples of the glitches:
In the Santa Monica haven, instead of the view from the windows over the streets, there is a wall. It looks like someone has knocked up a wall right on front of the windows. I suppose the game messes up the graphics and replaces the view with a random texture, but it's always that bloody wall! (I'm not playing a Malkavian btw, the wall really is there )
When feeding in nightclubs, the graphics go crazy when the camera does its twirly-whirly-aroundy thing, and the whole locale is graphically messed up until I leave and re-enter.
Some of the graphics seem to 'stick' to the first person view: the toilet sign from the diner, for example, hovers disembodiedly in front of my character and won't go away. Kinda ruins the immersion.
And so on. Lots of little errors; they wouldn't be so annoying seen in isolation, but there are lots of them, and they're all over the place.
Any of you clued-up peops know what the problem might be? The game ran fine on my old set-up (which is identical to my new set-up only with a better graphics card and more memory), and I've played through it something like four times, so I'm guessing the new graphics card (a GeForce 8500) is the problem, but it runs newer games as well as older games just fine. I have two GBs of memory, I'm running Bloodlines on highest settings, it's the three-CD version, I'm running Wesp's 5.0 unofficial patch, I have DirectX installed, everything should be in order, but isn't.
The bottom line is: I want to play Bloodlines, but I can't. Haylp!

Might be your drivers rather than your card. Bloodlines used to play fine on my 7900 gtx, updated the drivers, two different times, and Bang, it actually freezes now when I try to load it up.
