Not sure I follow your second sentence. Isn't there an option in the NV control panel to simply disable AF while leaving everything else alone, i.e. not touching other visual quality options or in-game settings? Regardless, the bottom line is that the chart is in the "apples to apples"...

IQ differences are often subtle and difficult to notice except in specific scenes. It is quite possible that the screenshots selected for the IQ comparison did not reveal the IQ differences from the missing render pass in the DX 10.1 run.

Exactly how I understood it. They said that their implementation of DX 10.1 removed a render pass, hence the performance boost. However, removing the render pass should actually decrease IQ compared with not removing it. Therefore in their current implementation, DX 10.1 has inferior IQ to DX...

Yes, in general a 2.33 GHz Conroe at 1333 FSB is equivalent to a 3.0 GHz K8 X2 and to a 2.6 GHz K10 X2. And then the new Penryn adds roughly 7% clock-for-clock to a Conroe, on average across all apps w/o the use of SSE4. So to compare to an E8400 Wolfdale overclocked to 4.0 GHz (very common...

I completely agree, and my personal suspicion is that the reason is Vista 32 vs. Vista 64. [H] used Vista 64 with the 64-bit drivers, while nearly every other site used the 32-bit OS. Much of the code between these drivers is very different and it is likely that AMD spent more time optimizing...

Kyle, what exactly were the FRAPS settings used? As 67shelby noted, FRAPS incurs significant CPU overhead and this would go part of the way in explaining the discrepancy between the timedemos and the real-time demos. If all that FRAPS is doing is logging the frame buffer flips to a file, the...

My point is that there are still "large amounts" of code that are different between the two drivers. And that is the code that we should be focusing on when assessing performance differences. Naturally, identical libraries would not lead to performance differences so those libraries don't...

Either provide links or quit sounding like a broken record. A quick review of the release notes for the latest AMD drivers shows a couple fixes that are specific to the 64-bit version of Vista, which indicates that the drivers are coded separately and that performance fixes may be optimized...

I agree. My point is that most of these sites did not use a 64-bit OS and thus there are wholesale differences in the drivers used. Drivers are the key. [H] used 64-bit drivers, the others (mostly) used 32-bit drivers. My suggestion is that AMD did not write the 64-bit drivers properly and...

The bottom line is that Vista 64-bit and Vista 32-bit are completely different operating systems with completely different video drivers. There is a very real possibility that AMD FUBARed the Vista 64-bit drivers and the performance gains that all the other sites using Vista 32-bit or XP are...
