Whenever I'm on voltrex (pretty sure this is just on Voltrex not on all of east, but I'll double check) I lose all environmental reflections on armor and any shiny textures become matte. Also, my head looks slightly transparent.
Could be on my side, but Rhiz's post about weirdness on Voltrex made me think of it.
Oh, and just to rule out one possibility, I haven't been turning off environmental reflections every time I go to Voltrex heheh
