Strange graphical bugs (video included)

[undying]

Sorry for the late reply. We have had problems with HD cards for Overture and we are looking into this.

EDIT: Does this happen on Low and Medium shader quality too? And what happens if you turn off post effects?

I tried setting everything to low or off and i even set off the post effect. Still the same texture bug. The youtube video was made using everything on high and AA 4x. I have tried everything , even the omega drivers. There is a difference. Some textures were repaired, but others were corrupted , overall no actual improvement.I just don't know what to do.
