IMO you can't get a full idea of the difference from screenshots.

Going from 7800GTX to XTX the most dramatic immediate difference (yes Im saying it again) is that the picture broadcast to my 2005fpw is much sharper on the XTX. I can see details in games I couldnt see before, much more... as far as actual AF filtering and all that, I like ATIs AF, not sure who has better AA though I did like nvidias SSAA

Do you still have your GTX? Honestly, I had agreed with you prior to making these screenshots, and I had somewhat expected the IQ and sharpness to be considerably better with the XTX. However. after running these two cards back-to-back in the exact same locations in the games, the difference really isn't noticable. The default color saturation on the XTX is generally more pleasing to the eyes though (it's warmer), and i think this actually has a lot to do with what you are experiencing.


It's not just that though man. It first struck me when I turned my PC on because while on the GTX the lettering in the bios and POST were basically a slightly blurry white, on the XTX I could make out each individual pixel making up the lettering. I can see details and artwork on medic packs, supply boxes, characters in BF2 for instance that did not come through before on my GTX ... HL2 EP 1 is similarly much more impressive looking... what monitor are you using? Your system is as top end as mine so I'm sure its a good one but just curious.

I do have the GTX (selling soon for 200 btw everyone) but I dont want to reformat to reinstall it to test.

If you can really see a difference in those shots you have better eyes than me.

Or you want to believe.

For me it wasnt in the shots, I didnt really look at the article, it was on my PC that mattered. I would have prefered Nvidia have better image quality (and HDR+AA for oblivion) becuase then I would have bought a GX2 probably but an OC'ed XTX is chasing it in most games at my res and the image quality is summarily superior ON MY monitor at least. Check that anandtech article, for some reason they bench an XT against the GX2. Add 15% performance to those numbers for an oced XTX. ( Of course you can OC a GX2 as well )

 

[nitromullet]

what monitor are you using?

I have the same LCD as you, Dell 2005FPW.

AA is actually mostly ROP and bandwidth intensive - it has nothing to do with shaders. That's where it helps to have a more efficient memory controller.

true. effecient controller does help, but it doesn't explain the missing objects.. must be a bug somewhere..

nitro: do fences disappear in all settings, or is it specific only with certain settings on?

Good question, since I still have the XTX installed from yesterday I'll check that out this evening.

 

[beggerking]

awesome. This is so much better than the other thread..

Maybe the white lines are there on Nvidias becasue of the AF angle. Do the different distances affect that?

Don't know about in that specific spot, but I mentioned the white line present in one of the screenies I took earlier. For me, that line flickers when I move. I have also noticed similar lines/flicker in other parts of HL2.

 

[josh6079]

Do you have you negativeLOD's clamped? If I remember right, that is supposed to help with some flickering that AA can cause on certain textures.

 

[Malladine]

The XTX jaggies seem somewhat less in HL2, WoW i can't see any difference and in Oblivion the XTX looks like crap compared with the GX2. I can't stand that overdone bloom on the ATI cards.

Yes. I've been clamping since the whole WoW/flicker issue was unearthed, and this was proposed as a solution. This is the best AF I can get out of this card.

It makes me wonder if the disappearing fences is the reason that the Radeons don't take as big of a hit in AA as the NV cards.

I brought this very thing up a LONG time ago. I stated that I felt ATI didn't "AA" the whole scene and NV did. Hence the much bigger performance hit. My notion was promptly attacked before being discussed. So I left it alone.

While I agree, I should point out that in all the Oblivion screenshots, the character is casting an illumination spell (you can see the cast cooldown on the top right). Overall, I prefer the look of the NVIDIA screenshot, but I am kind of curious were the glow went. This spell is the same reason that you see so much light on the character's hand with HDR. Although, it is daytime, so the glow is somewhat overdone.

I love the black and white responses, "7950gx2 looks like crap compared to the xtx". They look 98% the same in SS and 99.5% the same in action. Pick whichever card performs the best in the games you play.

You rate performance over IQ. Some people are the opposite. The GX2's IQ, to me, is absolutely fine. I wouldn't complain if I had nothing to compare it to. However, the AF from ATI's side clearly is the winner. Just because it doesn't matter as much to you or me doesn't mean that it won't matter to someone else. Fact is, performance will be good enough on both cards anyways, especially in HL2. What's wrong with making IQ a concern?

 

[Cookie Monster]

Is it me or some of the fences in HL2 seems to all but dissapeared from the ATi screenshot compared to NVs screenshot.

There is nothing wrong whatsoever making IQ a concern. Just don't blow it out of proportion. (Not directed at you, just general) There are subtle differences between both cards. Each is better at something, but not on the monumental scale people will have you believe.

EDIT: Nitro, I might be able to help you out with hosting and mouseover's if you wish. I can setup an FTP account for you if you can send me the original pics. Just make sure they are titled properly so I don't mix them up. I'll PM you with the info.

Ok gang. Web page is up with mouseovers.

It's self explanitory. Firefox users: Unknown if you will have any difficulty. It's just Javascript so I believe you will be fine. But please report any difficulties.

7950GX2 vs X1900XTX IQ comparison

 

[m21s]

WOW excellent job thanks!

The first HL2 pic says alot!
Look at the fence how it disapears on the 1900xt, i guess you can runs games with higher frames with AA when you make the stuff disapear

 

[skooma]

Good stuff, thaks nitro and keys :beer:

ATI Bloom in Oblivion looks terrible imo. HDR looks better but still looks like 7950gx2 for me as that is my main game.

 

[Markbnj]

I thought they looked almost identical up to the WoW bloom examples, in which the ATI looks way too bright. Then the HDR is almost a washout.

Nice, really nice. Thanks for hosting these and making a good comparison page. I updated the first post to point to your page.

 

[Rage187]

Hmm, I was hoping the XTX would have better image quality. Some what dissapointed.

er and yeah the HDR on the XTX looks way too shiny and blurry.

Gonna hold on to the 7800GT until the R600 and/or G80

It is interesting about the fences with the Radeon card. I checked it out with different settings as well 4xAA, 4xAAA, and 6xAA, and the same thing happened. I have also noticed in the other HL2 screenshot (thanks to the mouse over) that in general the XTX tends to make thin things (like tree branches) much thinner than the GX2, which causes them to disappear in some cases.

 

[Keysplayr]

In the HL2 shot, it looks like the GX2 renders the chanlink fence all the way to the end of it down by the tunnel. I also see what you mean about the ATI card making things "thinner". AF looks better on the XTX. Looks like there may be something to my old theory. But hey, you guys decide.
