Parallel lines in game. Any solution?

For a long while now, I'm seeing parallel lines running through the graphics in City. I've included a screenshot...



Sorry for the large image. You can see the lines just in front of me and another line behind the Tram structural post. They are constantly the same distance from me no matter how I move.

I've tried changing many settings but nothing has gotten rid of them. Any ideas?

System: Windows XP SP3
Video: ATI Radeon HD 4850 512MB

Thanks!

Are you seeing this in other applications?
Is there any difference if you change resolution or refresh rate?

My initial suspicion is it could be a hardware fault on your graphics card memory address lines or possibly the timings.

Try adjusting your shadow settings and ambient occlusion settings.

What video card and driver version are you running with?

If it shows up in screenshots, then you likely have a video card going bad.

I fail to see how graphics problems showing up in screenshots equate to a video card going bad. Many things can cause graphics problems to show up in screenshots, not just video cards going bad.

Horizontal lines on the monitor are usually a bad monitor or connection to the monitor. However, if they show up in screenshots, it is an issue with the hardware or software.

The OP can try to update drivers, change settings, or reinstall CoH, but the problem will likely disappear then come back eventually. From my experience, once you get artifacts, your video card went bad and needs to be replaced. In this case, it is likely bad video memory as Gaia pointed out.

The only other thing I can think of is changing your VSync setting.

I'm having exactly the same issue with my game. The horizontal lines mark the borders of shadow LOD. I've tried every permutation of the shadow and occlusion settings and they just won't go away.

Incidentally I'm running a similar setup to the OP: Windows XP SP3, Radeon HD 4650 1Gb. Latest graphics drivers, updated today.
