burningrave101 said:nVidia is ahead of ATI in BOTH DX9 AND OpenGL. To see raw performance of the cards you have to look at how they perform with AA + AF turned off. Thats the actual raw speed of the card. AA and AF performance has alot to do with filtering optimizations and the performance there can be easily increased in driver updates.
At 1600x1200 in DX9 the 6800u wins nearly every time.
At 1600x1200 w/ 4xAA in DX9 the 6800u wins every time.
At 1600x1200 w/ 4xAA + 16xAF in DX9 the X800XT PE wins a little more often then the 6800u but they are usually always neck and neck.
At 1600x1200 w/ 4xAA + 16xAF in OpenGL the 6800u wins every time.
Are you seeing where i'm going with this?
ATI's performance in DX9 titles relys on their AF performance. In 9 out 10 DX9 games the 6800u is going to beat the PE without high levels of AF enabled. Its probably even a higher percentage then that.
The 6800u's start losing steam the higher the AF goes. The X800's dont. ATI has so far been able to come up with better AF optimizations than nVidia. Thats about the only explanation i can come up with for the results.
nVidia has a much larger lead in OpenGL then ATI has in any DX9 titles. In DX9 the cards are tied for the performance crown because its entirely up to which DX9 game your playing and what settings your using. People keep looking at Far Cry, Halo, and UT2004 and think those account for the rest of the DX9 games out there and they dont at all.
If its OpenGL however, it really doesn't matter which game your playing or what settings your using.
Call of Duty and KOTOR were the two biggest hits of 2003 so why wouldn't OpenGL be just as important as DX9 even if there are more DX9 titles? Alot of the major hits get built around OpenGL. We've got Doom 3, Quake 4, the Call of Duty expansion and others coming up. All of them will be MAJOR hits.
If the X800XT PE was the faster card it would be able to outperform the 6800u with and without AF enabled and it can't.
I would like to find out more about ATI's AF and how it scales so perfectly with almost no performance loss at all.
Raw performance doesn't matter to me. I play with AF and AA under DX9 and ATI is the better value there. IQ looks as good as NV in that situation and performance is better for ATI, what's there to argue? ATI has a filtering scheme that doesn't effect IQ to gain performance. Lately NV hasn't been able to do that.
You must have me pegged as a ATI fanboy, but I've only owned ATI since the 9700 Pro. I would have bought a NV product this cycle and planned to, but they didn't come out on time. I bought the X800 Pro the first week they were out and have been enjoying it since. At this time there is no compelling reason to go NV for me.
Also, this thread isn't about the Ultra, it's about the GT. IQ is king as far as I'm concerned and the filtering of ATI has a lesser impact than NV with equal IQ.
You named about 4 MAJOR titles and forgot about ALL the others that use DX. Did you forget about UT? How about Pain Killer? Far Cry? Battlefield? MANY others. GL is here to stay, but it's the minority of MAJOR titles coded with that API. The fact is that most major titles are built and will be built with DX9+ from here on out. Don't get me wrong, I love GL and wish that ATI was better with it, but the developer community is focusing on DX.
