Wow, it seems that the Nvidia Focus Group members are busy today. Can anyone explain the bench I posted or not?
Did you happen to even read the text below the graph you linked to?
We have always considered Civ 5 an interesting game both for its near-complete use of the DX11 feature set, and because of its interesting performance characteristics. 2 weeks ago we called it CPU limited based on the fact that once we had sufficiently powerful cards, AMD and NVIDIA results tended to clump together despite any difference in their respective cards’ speed. With the Forceware Release 265 drivers, NVIDIA has blown this assumption apart, with NVIDIA’s more powerful cards launching ahead at 1920 and lower. We appear to be quite GPU limited on the NVIDIA side all of a sudden, which is about as drastic change as we could expect. Furthermore NVIDIA is holding their cards close to their chest on this – they’ve obviously found a wonder optimization, but they aren’t ready to say what it is.
There was a huge improvement in the game's performance on Nvidia cards when using the most recent drivers released with the gtx560.
Old drivers: http://www.anandtech.com/show/4061/amds-radeon-hd-6970-radeon-hd-6950/17 used when the gtx570 was released
New drivers: http://www.anandtech.com/show/4135/nvidias-geforce-gtx-560-ti-upsetting-the-250-market/9 used when the gtx560 was released
Nvidia cards got a huge performance boost. Before the latest drivers, all the cards were virtually tied in performance in the section of the game you are linking to. This has absolutely nothing to do with the performance of the game on AMD cards. What else do you have to complain about that can be easily explained and refuted?
