TweakTown checked out the latest Catalyst driver over here.
"This came as a bit of a surprise! AMD decided to release the 11.5 driver set which followed the massive 11.4 in the first half of this month. Normally we see the Catalyst driver come out towards the end of the month; this is more so seen after such a massive release.
It seems that AMD wanted to just improve Hydravision while doing the normal array of bug fixes which can all be seen below. With clearly not much emphasis being put on performance this time around, we're not expecting any miracles, but we'll see just what the new 11.5 driver has to offer over the previous 11.4 which we love."
