6800GS AGP: Bad jaggies
 
I just received and stuck in my 6800GS AGP from eVGA, the CO edition which is running at 1100/400 (vs 1000/375). I am getting wonderful frames, obviously, but I have noticed something that sort of bothers me, especially coming from an ATI Radeon 9800 Pro: Jaggies.

Now I know, you can get rid of jaggies using anti-aliasing, but I never had this issue with my 9800. It's most noticable in EverQuest 2, while in World of Warcraft I don't notice it at all. Turning on AA of any kind for EQ2 is really not an option, as that game already uses some power if you want to run it at anything but the basic settings.

So my question is this: Is this a known issue with 6800 series cards? Is this an EQ2 specific thing? Is it a driver issue? If there is something I can tweak to fix it, or at least lessen it, that would be great.

I am using the 82.12 ForceWare drivers, the first release (to my knowledge) that supports the 6800GS AGP. I know there are some new ForceWare revs coming out, but I don't want to go changing drivers just to change.

The only thing I can think of that would make the jaggies stand out more on the 6800GS is if you are running the games in a lower res than you did on the 9800. Other wise I have no idea why you would have just noticed the jaggies now.

I know why he's just now seeing them......everytime I buy a new video card, I scrutinize every pixel of every game I play for the first few days. :p It's my way of helping myself deal with the guilt of spending rediculous amounts of money on my hobby. So far, it has helped me reduce my guilty conscience because all of my video upgrades seem to have been good ones.

I say put that old 9800Pro back in and look at EQ2 a little more closely. The same if not worse jaggies will probably be there. You didn't by any chance turn up the image sharpening in the Nvidia control panel did you?

I am running the same exact resolution 1280x1024, same res I run my desktop in :)

Like I said, I don't see any jaggies in WoW, which is my primary game, where you would think I would scrutinize the most ;) EQ2 definitley has some jaggie issue that weren't there on the 9800 Pro. Thinking about it though, it could be that the 9800 Pro naturally renders everything VERY dark. While the 6800GS seems to have a much lighter natural color profile. This may have made the jaggies seem less noticable on the 9800.

I am not guilty about the purchase one bit, hehe...so I don't think it's that ;) I am sure after a few days I won't even notice it...was just curious if anyone else had seen this kind of thing when switching from an ATI offering to an NVIDIA one.

Have you tried different drivers?

The cards produce nearly the same identical image when working right

I am not going to start an IQ arguement. But I have to say that what he is experiencing is normal. The "jaggies" are more noticable on the nVidia cards when in motion if using anyhting less than 4xAA. They are not bigger or worse. Just more noticable. They roll or crawl more noticably in 2xAA or 0xAA modes. Like chainsaw teeth in slow motion. I have never been able to show this with screenies because when still they look the same. Like he pointed out, it's not in all games either. Just some.

After a long time on a Gforce 4 ti4600, I had a 9700 Pro which ATI replaced with a 9800 Pro in an RMA situation. A few years later I had an X800XL for a few months. I came back to nVidia getting a 7800GT. Very fast and I love it.

However. The first few weeks it took me a while to adjust to using the card. The crawling or moving jaggies were distracting. I was not looking for them and assumed that IQ was identical this many generations of cards later. I'd say they are just different now. :)

With ATI I often played games without AA in favor of going to a higher res. It looked fine. I prefered it. But with the 7800GT, anything less than 4xAA and the crawlies were there in some of my games. Farcry I saw em all the time. COD2 never.

Luckily I just run my 7800GT in 4xAA mode. So it's virtually unnoticable. Some of the games I need to go to 1024x768 with 4xAA to have fast framerates. But that's ok. Looks wonderfull anyway.

I do have a PC next to this one with an X800GTO2 in it that we use in the house. So I can see games side by side. But that's just it. They need to be side by side and watched to see the difference.

I think a long time ATI user is the only user that can see it. Which makes sence. A few years of training your eyes to one product game after game. You are bound to see the differences when you switch.

Aside from that, I ahve been VERY happy with this 7800GT. But if the X1800XL was not so noisy and about $35 cheaper I woulda switched to it.

Thanks for the response cvreal :) I am glad I am not totally insane. Like you, I will just "live with it", it's not that big a deal, and like you say, 4xAA can fix it (although, I will probably have to drop to 1024x768 in EQ2 as well, especially since I am on a 6800, not quite the horsepower you have).

One thing to try though is Gamma Correct AA enabled in the driver. Doing that with some engines, 2xAA looks a bit better. Experiment. :)

Also make absolutely sure you change the Image Quality to highest in the driver too. It will eliminate the texture shimmering in the distance. :)

I actually have to do some research, because my driver level AA settings don't seem to be affecting EQ2 at all, there still appears to be NO anti-aliasing occuring. I will have to dig dipper. For now, I have WoW running perfectly smooth with no jaggies, so I am happy with that.
