Stick with one of the 6.12 versions (I'm running 6.12.34 which was the last "stable" release) as the 6.13 are the start of a complete re-write and have had many probems, especially in the GPU areas.
In the newer versions of Boinc Manager (6.12.x) the message are nw in the "Event Log" wich can be found as the last item on the "Advanced" menu.
Please keep in mind that if you are only connected to GPUGrid I think you will still get this message as they do not yet support ATI cards.
While BOINC Manager should recognize FireStream dirvers it is p[ossible that it does not but that's just speulation on my part.
I'm planning on rolling back to 6.12.xx
I can copy/paste the event logs but they're going to show pretty much "No usable GPU found."
