I have the same problem. That's my post from a while back, we were never able to track down the problem. Everything else works fine, every other game has none of these type of artifacts.

The same exact thing happens on both my machines that share no common hardware besides the same series CPU and ram.
One machine specs

Video - MSI 8800 GTS 640 Core Temperature around 49 idle and 55 load With memory always around 44c. While these temperatures may seem high, the 8800 series of cards run especially hot and those temperatures are actually about 20 degrees under the average.

Motherboard - Gigabyte GA-m55sli-s4 rev 2 (Nforce 4 sli Northbridge)

Processor - Socket AM2 x5200 x2 Overclocked to 3.1 at 1.4 vcore (And yes i get the artifacts at stock speed and voltage as well.) Temperatures hover around 28 Degrees idle and 38 degrees under load

Memory - 2 gigs of gskill ddr2 pc6400 memory

On this machine it happens in Vista and xp Using every driver you can think of (trust me i've tried them all). Also i've tried every combination of settings in game and in the nvidia control panel.

And the Other Machines specs are

Video - ATI X850 XT Platinum Edition 256 Meg

Motherboard - Some Super Cheap MSI board, Via KT 800 Northbridge

Processor - Socket Am2 X3600 x2 (Stock clock)

Memory - 1 gig Gskill ddr2 pc6400

Only tried this machine with XP, But i've used every driver from 6.1 to 7.5. Temps are a little higher on this machine but well within spec.

All other games work fine, and in fact some maps in PR don't see much of this issue, it's still there but you have to look close to see it. But the desert maps generally make it super obvious. Check out the video i posted in my realitymod.com link.

And to the OP try Wake Island 2007 in a 64 player close to full server, if you're US you will probably get the artifacts there too. So it's not entirely PR as much as what seems like a flaw in the BF2 engine for certain hardware configurations.
