With 0.7.1 you have put the png's directly in the media folder instead of in a subfolder. This makes the texturethingie put it all in gpu memory, (cache) wich will reduce videomemory by 64Mb (2x32Mb cache texture png's). If you run out of videomem, several dxerrors, mouselag, slow skin responce and other shit will happen.
In the older versions, the textures were put in a subfolder, and I think that is the way to go safely.
