i've installed vampires on my machine and it worked fine. i've heard reports of geforce owners finding graphics problems but i haven't had any and am running it a res of 1280 and 32 bit.
my spec is
PII 333
128 Megs of Ram
Intel bx2 motherboard
Geforce ddr
and sblive
the only prob has is game won't allow me use eax as it says it isn't supported
apart from that it runs like a dream
