Fall 2003 Video Card Roundup - Part 2: High End Shootout

Back to the game...
Since NVIDIA can't do floating point textures, PS2.0 shadows were left off, and we didn't use the NVIDIA shadow (depth sprites) for our cards as ATI doesn't support that. We have decided that since the glow effect uses PS 2.0 (and we are using this as a DX9 stress test rather than an actual game) this needs to be enabled. The 'goodness' of the glow effect has been questioned, but we aren't here to critique the quality of the implimentation. We simply want to test the raw power each card has to push TRAOD PS2.0 code. Personally, I think the effect glow had on the wall lights in the Paris demo was one of the only "pretty" things in the game.
Depth of Feild (DoF) is also on. After watching this demo hundreds of times, it really seems to me that using PS2.0 for DoF in TRAOD was overkill for what they ended up with. It just seems like they could have gotten similar results (with better frame rates) using lower detail (frequency) mipmaps and dynamic reduction of geometry. Of course, I could be way off base, but it just seems like there were better things that could have been done with PS 2.0 in this game.
We note that there have been issues with the accuracy of the Depth of Field post processing, but we think that the new 50 series of Detonators (along with the Cg compiler) will alleviate this issue. Of course, there are still some IQ issues in ATI's 3.7 cats.
As games and hardware move forward, post effects like DoF and rendered textures are going to be getting more and more complex, and the way hardware handles these things will be slightly different. It's less important to look at pixel level "sameness" between two solutions, but rather at overall image quality, and the impact of the effect. The user experience is what matters in this arena, and some things are going to be subjective. Pixel shader effects are much more intricate than geometry or T&L, and differences in architecture, precision, and drivers will all contribute to slight differences where no solution can clearly be labeled as more correct than another. Of course, that makes our job harder, but it will definitely be an interesting ride.
Anyway, in order to try to understand exactly how DX9 PS2.0 is affecting each graphics card, we are doing two tests at each resolution (with and without AA). The first test, everything we don't need to see something and have PS2.0 functionality is disabled. For the second test the only thing we do is turn off PS2.0 and run the benchmark again. The scores we will be giving you are in the form of percent decrease in performance when PS2.0 is enabled. This should give us some idea of how this implementation of PS2.0 scales on each card, and give us a good solid glimpse into the implications of DX9 in TRAOD (as this is the only game that will ever use this engine).

You need to look at the FSAA each card empolys...go back and look again at the screenies, this time looking at all the jaggis on each card....especially in F1, it doesn't even look like nVidia is using FSAA....while on the ATI, it's smooth ......I don't think it's a driver comparison, just the fact that ATI FSAA is far better at doing the job....At least I think that's what he's talking about..hard to tell any IQ differences when the full size screenies are not working, but poor FSAA kinda jumps out at you (If your'e used to smooth FSAA)Also worth noting, nVidia made great jumps in performance in DX9, but nothing that actually used PS2.0 shaders : (

#14 Blurred? Are you not wearing your glasses or something? Nice and sharp for me...Anonymous User - Tuesday, October 7, 2003 - link

I like the way he discounts Tomb raider. Saying it is just not a good game. Thats a matter of opinion. It almost seems like he trys to undermine that game before revealing any benches.And the benches for that game are not done in FPS but on percentage lost on PS2.0.
On first inspection of the graphs it appears that Nvidia is leading in tombraider. But if you look at the blurred print on the graph it does say "lower is better" Very clever!
Why no FPS in that game?
Nice information in this review but it almost seems that he is going out of his way to excuse Nvidia.
I smell a rat in this review.

#3, #7: If you take the screens into photoshop and observe the result of their 'difference', you'll see that there's a fairly significant difference between the 45's and 3.7's, but almost no difference whatsoever between the 52's and 3.7's. In most of those screenshots it's impossible to do this since the shots aren't neccessarily from the exact same position each time. Try the ut2k3 ones for example. Also these are jpeg's, so there'll be a little fuzz due to the differences in compression.Also, if I need to take two screenshots into photoshop to be able to discern any difference between them, that's really saying alot. And since we can't refer to a reference software shot, it could be ati's driver that's off for all we know.
In any event I'm pleasantly surprised with nvidia. Their IQ has definitely caught up, and their performance is quickly improving. Hopefully the cat3.8's will pull a similar stunt.

No he's just a "fanny"AgaBooga - Tuesday, October 7, 2003 - link
They must have a reason for choosing those drivers. Anandtech has been around long enough for that :)The reason is probably along the lines of when they started this benchmarking because they did soooo many games, resolutions, AA and AF levels, times the number of different cards, etc. That takes quite some time. Had they waited for the newer ATI drivers, it may have delayed this article one, or even two weeks till publishing. Also, they did mention they will do a followup articles with the new drivers, so patience is the key here.

well #8, Nvidia was able to do it with the wonder driver, I dn't see why Ati can'tAnonymous User - Tuesday, October 7, 2003 - link
LOL, the ATI fanboys are already coming out of the woodwork. Listen #3 and #7, it's a fact, there is no IQ difference at all between the 50 Dets and the 3.7 CATs. And if you honestly believe you're going to see much of a difference with the CAT 3.8's....you're just stupid.
