Bioshock

My PC is getting a little old now but I really want to play bioshock so
I've been trying out the demo.

I've got:

P4 3.2
1.5 gig DDR ram
Abit IC7 mobo
AGP 6800 GT

Unfortunately it just runs a bit poo, I've dropped the res to 1024x768,
lowered most of the settings but it still slows down a fair bit when
there's any action which usually results in me getting a smack round the
back of my head by some mask wearing fool.

Running the 162.18 drivers, gonna try the beta ones see if they make
much difference shortly.

Given the mobo I have etc (no pci-e, DDR2 etc) I'm limited to what I can
upgrade, as when I do replaced the kit it'll all have to be done.

Any suggestions?
