When I render with harware renderer the textures looks the same as when in normal shaded mode (distorted)

On most of the models in the scene the texture looks good but on some of them they look as on the pictures.

and on the grass texture it looses its colour and if I look close to it I can se red, blue & green lines (dont think you can see that in the picture I provided though).

It could be the graphics card, but if it is it would be kind o strange. the card is a 3d labs wildcat realizm 800 (and this is a ultra high end gfx card that costs around €2000) that was buildt for this purpose and even have its own "maya setting" in the driver.

I just want them too look as they should even in normal shaded mode
