Oblivion might not recognize newer graphics cards and could put all the graphics settings on low, that can make it look very washed out. Not sure about things being double though. You could try deleting (or moving) the oblivion.ini file so it has to redetect your hardware then fiddling with the graphics settings and see if it looks any better.
