Hi guys, I started playing DoW1 again and I have a weird graphical bug.
On the first attached pic you can see what is going on. Note that this happens ONLY with Imperial Guard's Mechanised Command building.
Also in DoW: Winter Assault I see weird textures on IG buildings and banners (see the second pic), but in Winter Crusade and Soulstorm it is OK.
In b4, my graphic card is GeForce 7600 GT (and it did the same on my Radeon x800) and my GC drivers are up to date.
Does someone know about any solution?

Toy around with detail settings, if you're using widescreen, DoW doesn't handle it well. That worked for me - yes, I've had the same bug

There is like a million patches for DoW, I assume you've installed all these too. Luckily you can update it from 1.0 up to 1.41 in with one patch.

I seem to remember texture corruption in an earlier patch of the game. But I can't say I've seen anything like that recently. I will give it another look later on and get back to you.
One graphical setting you may want to test is forcing vsync on or off using nVidia control panel (right click on your desktop and the option should be there). Go to Manage 3D Settings - Program Settings and Add settings for the exe in question. Try forcing vsync off then on for that exe and see what the results are in each case.
Vsync is a common problem area and even if it doesn't help you with this game, it may with others.

If I remember correctly the original game and Winter Assault share the same patches while the other expansions are stand-alones.
You would probably need these three patches:
1.41

1.5
http://dawnofwar.filefront.com/file/Dawn_of_War_Patch_15;65318
1.51
http://dawnofwar.filefront.com/file/Dawn_of_War_v151_Patch;68326
Because I got the game late I've only ever played it with these patches and I've never seen any glitches.

Are you using Antialiasing or Anisotropic Filtering? Try toggling those as a first step. Have you modded the INI file in any way?

Fenixp, Navagon: I have tried various game settings as well as nVidia control panel (Vsync) with no results.
Romulus, Lenny: I have Steam version of DoW, so it should be up to date. For example Winter Assault is 1.51. I'm sorry that I forgot to mention this fact.
Aliasalpha: AA is according to nVidia CP off at gamma correction and transparency. AA- setting and Anisotropic Filtering is application-controlled, but in DoW graphic config I can set only resolution + color depth and screen refresh rate, nothing else. But I'll try to tinker with those through the nVidia CP.
