Blood flood

[Digby Tatham Warter]

The only time have had major distortian on RTW was using a blood mod.

But sometimes I get a line/block I think during dust clouds/or river battle, they are basically transparent, rare, and only last a second, they seem to rise up from the floor and disapear after reaching the top of the screen.

Was your GPU overheating perphaps? Is it overclocked?
