Well it's supposed to be the X1300LE and at 8fps it would be pretty silly to turn on the AA. This may not be the only reason why AA isn't on, but I guess it's understandable for an entry level card to have such a low frame rate in such a game.
Yeah, 3DM05 is GPU limited & puts into perspective vanilla 6600 performance with default fill/bandwidth limitation. Most 128MB versions will oc to 500/750 yielding handy performance in shader limited situations. It's also interesting that G70 is vertex setup limited in 3DM05. I wonder where R520's bottleneck will be...
