This thread is exactly what I'm looking for. At first I thought it was just a "low setting" issue. Then I saw many fancy effects that were apparently invisible for me, and asking a friend (with the same lowest settings), he confirmed that he can, in fact, see them.

Level up effects are also missing for me, as well as the ring of fire and whatever has been mentioned here.

I'm on a 7900GS.

I made another thread detailing this issue in more detail (here).  GPG nor Stardock have had anyone confirm it as an issue yet though...

Thanks for the heads up Shirley.

Well I hope the GPG guys can do something sooner then later probably not very high on there priority list.
