Irritating rendering artefact

I've been experiencing an irritating flicking rendering problem. The screenshot is was made running TGE HEAD with the latest Synapse Gaming Lighting Pack and scenery from the Tim Aste Content Pack. Note the black stripes on the right center.
As you move around these patches appear, on various surfaces, flickering between various patterns and then disappearing. It looks like a case of z-fighting to me but I'm not clear why it has just started happening to me or what the black surface is which is breaking through.
Any ideas on what it is or how to get rid of it?

The strange thing is that I haven't noticed it in other scenes I've used - though they're not as geometry intensive as the scene shown above.

No, I'm running in 32 bit mode. On a mobility radeon 9700 for what that's worth. DirectX 9.0c (4.09.0000.0904).The strange thing is that I haven't noticed it in other scenes I've used - though they're not as geometry intensive as the scene shown above.

What's your visible distance?

I'm using the demo scene from the Tim Aste Content Pack which has a visible distance of 250 on the sky object.

You mean 2500? 0.o

That IS really wierd. I wonder why it's only doing it on that one face....

@Tim - It actually does it in a few places but you can only catch it here and there. If you take your demo mission and turn off the precipitation effects you'll see it yourself, particularly when walking up to a fogged out large building in the distance.
Thanks again Ben.

@Ben, yup - you nailed it. Thanks! Increasing the visible distance makes the problem go away - or at least be so far away it's not visible.@Tim - It actually does it in a few places but you can only catch it here and there.

Thanks again Ben.

Quote:Increasing the visible distance makes the problem go awaythats odd. it probably just shifted the problem around. _decreasing_ the visible distance should make zbuffer problems go away, if that is what the problem is. unless that rendering error in the picture was about 251 units away from you :)

Now can you effectively decrease the distance without bringing fog in closer?

If it's really Z-fighting, switching to 32 bit should get rid of it.
