I recently changed my Radeon 9700 into Radeon 9800Pro, installed latest stable Omega drivers and started playing LFS. Everything was ok apart from this:

The nearest polygons to the camera posision are rendered very weirdly.
I thought it due to the drivers but i changed it into latest ATI Catalyst but the problem remained. I don't observe this bug in any other game.

The performance is also a bit lower than it should be. I'm doing now 50/60fps. On 9700 I was doing 70/80.

Mine did that the day before it died on me. Gradually got worse and worse (the extra polygons moving further and further away). Keep an eye on case temps and voltages. If you've overclocked it, now is the time to stop.

Good luck, and hope it's just me being paranoid.

It's a bit weird ... but I turned "Haze effect" off and everything seems fine now. :bannana_p

I have never been doing any OC with this Radeon so I don't see any reason for this bug.

BTW what exactly "Haze effect" does? I didn't see any difference between screens with this on and off

Haze Effects should make a difference in how things look in the distance. Like in that screenshot, you would see a very clear picture and see things very far down the straightaway with the option turned OFF. But with it ON you would have a 'haze' effect which makes distant objects look 'foggy' like in realife. The farther something is, it is in a certain layer of haze, which makes it harder to see.

It used to make a difference with it ON/OFF, but now it just stays on all the time and I don't know why.

Although I have an Nivida, I found certain drivers done this. Try ATI Cat 5.1 drivers.

i too am having a problem with artifacts, i am running a 9800XT that was serously overclocked and volt modded back in the day. Here are my system specs:
Abit NF7-S
74gb Raptor
120gb WD PATA drive SATA conversion
1gb PC3500 2-2-2-11 timmings
ATI 9800XT that is now stock
650watt enermax PSU
dvd/rw
mucho case cooling

It looks to be a core overheat problem, it looks like pepper all over the screen, and my GPU core temps never go over 65c. but this is the only game that it does it on. i play Battlefield 2 at max settings with no problems. drivers are the latest nforce2 drivers and cat 5.1's

If you need anymore information please let me know

Usually artifacts like that are due to weird RAM on the card. Just like the occasional vertex displacement you get on NVidias...
Try slowing down your RAM a bit, and see if it still works.
LFS seems very sensitive to this, compared with other games.

i replaced my stock XT fan with a 65CFM 80mm fan on the stock heatsink, core temps are down to 55c and mem temps are at 40c. pepper went away...

I'm runing a 9800 series card, and although I can't be specific about what causes the problem you describe, i've seen something very similar when I used to play Far Cry, but only ever in Multiplayer. When playing LFS in MP mode I sometimes get random mid grey coloured sheets rendered across the screen at interesting angles. They look like walls and more than once I've slammed on the brakes only to pass straight through...

I do know it's not restricted to overclocked cards [mine isn't] and I doubt it's specifically a driver/direct x problem, since I've changed both on my machine as games demanded and still occasionally get funky errors.

I just decided that I'd been slapped by a random gremlin, and left it at that. sorry I don't really have anthing useful to say other than "you're not alone" [cue Olive]
