anyone who's had both a 7800gt/gtx and x1800/x1900

curious.. what makes u think there will even be a card out that will run ut at those resolutions/framerates when ut07 is released?

i mean, is there a setup now that will run, say FEAR at that res/rates?

Only if you turn off the eye-candy. Even Crossfired X1900XTs would have a hard time staying above 60fps in FEAR at that res.

As long as no soft shadows (soft shadows in F.E.A.R. make it look worse and are poorly optimized) Crossfire X1900XT would play it 1920x1200 @ 45-50 FPS at least.

Anyway I dont have either of the cards, but I'd highly recommend ATi for performance and image quality mainly because of better Anisotropic Filtering and doing HDR and Anti-Aliasing at the same time.

AF: ATI wins this hands down. Once you know that NV's is angle dependent, you can actually watch it change as you move from side to side (change angles). That being said, neither is bad by any means, but ATI definitely looks better.

AA: Both AAA and transparency (esp super sampling) AA are great. After playing with these features, it's hard to imagine games without them. Overall though, I give the AA win to NV for single cards simply because NV's max AA is 8x and ATI's is 6x, and there is a difference. Again, neither is bad, but I think 8x AA just looks less jagged.

HDR+AA: I don't know, I haven't tried it.

Someone else already mentioned that the colors on their ATI card simply looked better, and I have to say that I agree. The colors are overall deeper and just more pleasant to look at with the ATI card. Personlly, I think this is the main reason that people have been claiming that ATI has better IQ all this time.

*Ex 7800GT then GT / SLI owner, now X1900XT*

I pretty much concur. Honestly, I thought the color thing was in my head but I am seeing more and more people say that.

The AF / IQ is the one people really tend to call a wash. Personally, I notice the difference in filtering quality quite a bit, especially in EQ2's landscapes,rolling terrain etc.

If you scroll down to the bottom of this page, it will show you a comparison of the AF between the two companies, but honestly this is one of those things you really need to see in motion.

There are also some comparisons of the AA earlier in that review I believe.

Are there any screenshot comparisons showing this color difference? I would be interested to see exactly what this is. It sounds like something that the digital vibrance thing on Nvidia cards may help with.

Regarding the AF, are you guys comparing the default modes or the highest quality modes on both cards? The 7800's default quality AF is junk IMO, but using the HQ / LOD clamp settings makes it look way better.

 

[aggressor]

I always use the highest quality control panel settings on my cards, and ATIs was way better.

I just sold my XT. Had it, and my 2 GTX's at the same time to try them out. I wanted to see first hand the difference. To me, the XT has enough of a image quality difference to get it. HQ AF in the XT looks great, better than my GTX. I didnt notice a difference in the AA quality though. I wouldnt even think about getting a GTX at this point, unless the price was very low. A X1800XT is cheaper, and faster.

Just sold your XT? You know something we don't Ackmed or just want to try out the new cards coming out?

I always used the HQ setting, I had never changed LOD clamp though, does that make a noticeable difference ?

That picture from [H ]'s review answers both your questions... They are showing the highest AF IQ for both cards, and if you look at the pictures you will also notice that the Radeon screenshot has warmer colors as well.

Edit: wrong screenshot

Edit 2: There is absolutely nothing you can do with a GeForce 7-series card to make its AF match that of the Radeon. No LOD Clamp or HQ settings... It's that simple...

I had a X1800XT, and just wanted to try it first hand. Ive had my SLI for a few months now, but wanted to see the XT for myself.

Now I am seriously thinking of selling my GTX's (they are actually FS now in the FS forum), and getting 2x7900's, or just a single XTX. I play BF2 the most (90%) and a single XTX is actually faster than 2xGTX's. So for me I may be better off with a single XTX. Not to mention it looked better, with HQ AF, and no shimmering. And I dont want to wait till after 7900 reviews come out, and rumors come to pass thats its 10% faster than a 512MB GTX, and just $499. I wont get anything for my GTX's then. :/

Ah. I thought you meant an X1900XT. I just made about the same move you're thinking of. Sold my 7800GTs@550/1300 in January for my X1900XT. Very happy with the decision.

I don't see any difference in the colors in those two screenshots. I know about the angle dependency issue but I'm more interested in how much better the shimmering is, as I find that far more annoying.

I am not very happy with SLI due to its numerous vsync problems and am looking to move back to a comparably fast single card. The X1900XT/X seem to be a little slower than what I have but if the IQ differences are significant, it would make up for that. Although I'll wait for the 7900s to come out before buying anything.

Yeah, that helps a lot for me. I think it somewhat reduces the effect of AF, but it looks much better than the heavy shimmering that results without it.

i think at this time i have little choice but to play "wait and see" for at least a couple of weeks. while it's difficult as i was already for the upgrade, with ati's announcement of lowering prices shortly after the nvidia launches the 7900 series, there's just too much going on to NOT wait...

bummed.. i was really looking forward to this

what is your opinion on the ati highQ AF? noticeable difference from 7800?

also what is your opinon on the overall AA differences? transparency AA make a difference?

thanks for the input!

I have a BFG 7800gt and an ATI X1800 512MB. I lean towards nVidia generally, but I have to say that the X1800 has the best graphics by far that I have ever seen in any video card. If your primary goal is image quality then based on first hand experience I would have to vote heavily for the X1800 512MB.

PS.
haven't really analyzed the various AF and transparency AA settings yet. I typically pump everything as high as possible while seeking decent frame rates. The X1800 is powerful and has beautiful graphics. For example, on Half Life Coast, with HDR full, and everything pumped at 1280 X 960 I score 100 fps on the stress test with my rig (see signature).

 

[hemmy]

tuteja, if, but it doesn't, that has been shown. It is equal or slightly ahead of the 7600GT

Oh yeah, and all these people talking about "warmer" colors, more "vibrant" colors, is purely subjective. My ATI cards look far less vibrant than my NVIDIA cards in my OPINION. None of that is fact. It cannot be proven, just in my experience thats what i see.
