intersting, but this looks more like a case of the driver bug, but in this case 16X AF being on/not on ...this is apparent in the textures on the road path. I tried something similar in 2 consecutive reboots as well :
no HQ 16X AF: http://i59.photobucket.com/albums/g319/stranx44/ATIHDRNoAA-16XAF-Wall.jpg
HQ 16X AF: http://i59.photobucket.com/albums/g319/stranx44/ATIHDRNoAA-16XAF-HQWall.jpg
i'll give it another shot tonight to see...
p.s. saw the rest of the thread, seems our joker friend likes to argue no matter what hehe....
which driver are you using? i've stuck with cat 6.3 as 6.4 seems to have some issues, and doesn't really offer anything over the 6.3 with the "chuck patch"
well, it's a slightly different angle you have between the 2 pics, but it looks like the same amount of filtering is applied to both (no aa tho? man that looks like ass!).
let me know where you took that shot and i can do some comparisons.
i also have some other pics comparing HQAF mode.. will have to find the right links tho.
lol.. yea, i linked to the single post because i didn't want get off topic with all that other crap 😉

I thought 6.4 was more stable for me, 6.3 had issues with some screen tearing and other image quality nuances for some reason. but the pics should be identical, just taken a slight milisecond or 2 later after reloading the save, thus some of the trees moved hehe...i took the pic though in the southern section of imperial city, forgot exactly where offhand (was running around aimlessly looking for a nice straight wall to do the IQ comparison hehe).
btw> send me your emial in PM and i'll try to get u the saved files of these places...

Using hardware mod is not a valid overclocking argument no matter how many times some fanbois say it. I said this with the AMD pencil trick and still stand by that. For a default the XT is if not = to the 7900GT it is greater then it in some situations just like the GT is in less situations beating the XT. So settle down boy before you get banned, seems as your account is suddenly active all of the sudden with rants and little word phrases that make little sense if any.

.... you are not making any sense....
how can it be an invalid OC?
If a sub $300 card can be OCed to perform like a $400+ card, then the $300 card has better price/performance ratio.

is the 7900gt vs. the 1900xt even a fair comparison? I was thinking that when I was beginning to read, then I saw the numbers and was quite surprised. 7900gt owners must be real happy, and I now understand why it is even more appealing, with the extreme overclocking.

I kind of like it, 5150 reads it as someone setting the X1900XT up to fail by giving it higher image quality settings, i read it as a review where the writeup is unjustifiably ATI skewwed in it's language. 😀
why do you think the OP might be "skewing" toward the XT?
consider he was a pretty proud GT owner who got great performance from his excellent overclock.
could it be maybe he's trying to be objective, and in doing so eh finds that the XT has things to like? or that it offers some advantages that can't be matched by simply overclocking the GT?

The 7900GT wins in terms of fps, but then it is lambasted for image quality that should be seperated into another section according to the author.
Too much subjective commentry to be a good review imo. The summaries attempt to be definitive but makes an utter hash of it. I think that the summary has been rewritten somewhat since i first read it.

Whether a hardware mod is valid or not for use in overclocking results depends on the difficulty. The pencil mod on Athlons is definitely allowed as anyone can spend 10 cents (or likely less) on a #2 pencil and $1 on a bottle of alcohol (in case you mess up) and do this mod. It also doesn't take a rocket scientist to do it either, just some care. Likewise, the 7900GT volt mod is simplistic and can be done with little difficulty if one has a steady hand and excercise care in drawing the lines with conductive paint. If the mod involves removing the IHS then sanding the core, or involves desoldering pieces and soldering things then I'd say not to allow it as most people don't have a small tipped soldering iron and steady enough hands to do the mods.
The other thing is, I'm not sure ST was going after a true oranges to oranges comparison but getting some playable frames out of similar settings. The thing is, the X1900 fares very well considering that even though some of the tests show it losing in the framerate department, usually the tests are with higher quality settings. If the people are too stupid to see what ST writes when he even lists what settings he's using for each test then that's not entirely his fault. ST is not responsible for the reading comprehension level of others.
BTW, the 7900GT core pretty much loses it's cooler core and lesser power usage advantage once it's core is clocked in the 7-800mhz range with a 800-850mhz ram. If you were running stock, yes, this thing takes much less power and runs much cooler. But at stock the X1900 creams it in the performance department as well.

Yep, the high end ATI cards suck in too much power to be cooled silently. Thus my descision was made for me. However if you're going to go to all the trouble of doing benchmarks and then decide to ignore them completely when it comes to writing the summary it's a bit stupid don't you think?

Note that there is one more section yet to be completed that will address power, heat, etc. concerns. if you didn't notice already, i already mentioned about the absurd power draw when utilizing the X1900XT necessitating me to utilize a more beefy PSU.
what benchmarks were ignored?
your comment about 7900GT winning is wrong on so many levels i really didn't feel the necessity to get into it with you.
ignoring the whole iq/features issues, while i could agree with your comments about passive cooling, that kind of throws your whole overclocking/performance thing right out the window, doesn't it? kinda makes your entire point.... entirely irrelevant. :shocked:

Eh, some people are being hard on ST, seems like he did a pretty thorough review and gives credit where credit is due.
ATI has this round. The volt mod 7900gt seems like a good performer but somebody needs to figure out a way to change voltage through software like with ati cards.
However, I take issue with all the colorful commentary he throws in the review. First, constantly pointing out the chuck patch is unsupported? You are writing a review for this forum, we all know. Second, all the stuff about slaying beasts... blah. Just give technical details with the most basic comments necessary like "nvidia good, ati gooder." Also, you should make a new name, maybe Pollo. 🙂
