Building Surfaces "Flickering"... Causes?

[bnsf50]

Well, I tried it on another route and I get the same problem. The problem now seems to happen when the time is forwarded to night.

Must be a video card issue.

It may just be a video card setting. You can go into the video card settings through your desktop video card properties and make sure that all of the sliders are set to max. Also make sure that your drivers are up to date.
You can also, and this would be the first thing I would try, Change from Direct X to Open GL or visa-verse in Trainz Options.

I tried switching to DirectX but some textures are blank. This really isn't a HUGE deal for me as the flickering will go away, I'm just VERY relieved to know my Trainz installation wasn't going down the toilet.

Have been having the flickering building problem too. Was okay on older PC with Nvidia FX 5200 vid card. Since replacing PC with one using Nvidia Geforce FX 5950 Ultra this problem has started. Most noticable on NZ low poly houses, but on a lot of other buildings too. Effect disappears when close. Changing from directx to openGL makes no difference. Doesn't seem to be viewing angle but distance, further away more flickering across windows. Have tried changing card settings but a few times but no better result yet. This is in both TRS2004 and 2006. Haven't noticed this in other games.
Cheers Will

If the flickering is across the windows go back and read post #7 for the answer. If its the whole building then that's a different story.

If the problem is caused by the alpha channel of the windows, is there a way to overcome this in card settings? This didn't seem to happen on low specs PC with different vid card. More noticeable on lighter coloured buildings and some fence splines too, like chain link fence. Some light coloured locos like UP U50 flash when rounding curves.

This may help: add the line, "-znear=0.80" to trainz options. Found this in Trainz Objectz, seems to work to some extent, any higher number than this and cabs don't render properly in cab view. Worth trying anyway. Flickering effect doesn't seem so obvious.

I got the same thing happening also since upgrading to more RAM and a big video card..... flickering on some buildings that never did before.

Annoying but I can live with it.... :wave:
