I fixed my problem long ago.  Post your specs and we can troubleshoot if you'd like.

Could you please be more specific on how you managed to fix that? I'm having this very issue, but in my case it affects every other DX9 application, but doesn't affect DX10 or DX11 apps.
My specs are:
C2D 6700 @2,66GHz
Gigabyte GA-965P-DS4(rev. 3.3) motherboard
6 GB RAM
GV-N450OC-1GI
video card
Thermatake Toughpower 600W PSU

Sure... I believe your Gigabyte card is also a GTS450.  What I found was that the disparity between the memory clock speed of the CPU/Motherboard/Ram and the video card's DDR5 memory clock causes the spiky issue.  From what I read online, yours is even more "factory overclocked" than mine.   Here's the solution I orginally posted:

Hi,

I may have come up with a
workable solution for those of us who are having polygon/texture issues
with Nvidia GeForce cards... I'd be interested if someone else would try
this and see if they can duplicate success.

After heeding a lot
of good advice on this forum about overheating, I did a pretty detailed
cleaning of my case.  Alas, it did not solve the recent issue I was
having with my GeForce GT 450 and massive graphical errors... which you
can read about in the threads below:

Anyway,
I decided to play with the clocking on my graphics card.  The GT 450
(along with other problem cards, like the 8800 and 8600) come "factory
overclocked".  So I downloaded Nvidia System Tools 6.06, and fiddled. 

Long
story short... I found that *reducing* the GPU's Memory Clock (NOT the
Core Clock) by about 20% solved the problem immediately!  I've played
through for about an hour and also played through a few previously saved
areas that were graphically intense... no spiky thingys!  I intend to
put in a marathon session tonight to see if the results hold.

Why
has this worked?  Frankly, I am a rank amatuer and have no idea.  I can
only speculate that the problem comes from a disparity between my 2+
years-old CPU/RAM/Mobo and the new graphic card's DDR5 super Fermi
whatsits.  DA seems very CPU intensive for graphics.

BTW... I am
using the latest Nvidia driver (I have no choice with my card) and
running the game at 1680x1050 with all of the in-game settings maxed
(including vert sync).  I am getting about 30 fps for most play.

Hope
this helps some of you who've been as frustrated as me with this
long-standing problem.  Again, I'd be thrilled if someone wants to try
and verify the results on their own system!

Hope that helps,

Thanks for the detailed explanation. It's a pity that in my case it didn't help. I guess I'm just having a bad GPU since another video card (Asus EAH4850) worked fine, and gts450 showed a lot of errors in various tests. I'll try it in another computer and then I guess I'll return it while I still can,
