Black floating graphics of doom

[meta-redundant]

I haven't seen this posted anywhere else, and didn't find any thing on the (ironically titled) Ubi help section, so I'm posting this here in case any of you have seen it and have any comments! Here's what I am seeing:

--> Large black triangles and other strange shapes protruding from my sub when viewing it using the external camera. Some of them look like they go 1000ft into the game world.

--> Random tears and protrusions when in the command room, to the point I can't make out any of the crew, let alone read the gauges.

I used to run this fine on my 7800GTX, but recently upgraded to an 8800GTS and this is when all the trouble started, but only with SH4. All my other games run fine (in fact, brilliantly). I have the latest Forceware drivers (163.75) and confirmed this in the nVidia system dialog.

My setup:

Dual Pentium 2.8GHz
nVidia 8800GTS
2Gb system RAM
SH4 v1.3

Any ideas guys? It's a bummer...
