Do AMD's Radeon HD 7000s Trade Image Quality For Performance?
We discovered blurry textures when we reviewed the Radeon HD 7800s, so now we're performing an in-depth investigation. Why does the Radeon HD 6000 series demonstrate crisper image quality? Is performance affected? Does AMD know about the issue?
A Texture Quality Problem Confirmed And Fixed
We did, in fact, find texture quality anomalies in AMD's new Radeon HD 7000 series, and we were originally concerned that history was repeating itself when we discovered the problem. If you've paid any attention to the graphics space over the past 10 years, you'll probably remember a time when ATI and Nvidia quietly played around with image quality, sacrificing visual fidelity for performance in order to help their products perform better in high-profile game benchmarks.
To be clear, the discrepancies we found on the Radeon HD 7000 cards aren’t obvious until you start poring over screen captures. With that in mind, we're still reminded of a time when some folks argued that optimizations are acceptable if they're not noticeable during game play. Despite this contrarian view, common sense won out in the court of public opinion and users made it clear that they wanted to see the output quality that the developer intended. Since then, it has been acceptable to give players the option to lower quality in exchange for performance, but the default setting is sacred, and we expect a similar experience across all graphics cards when it's employed.
Based on our original findings, it wasn’t a stretch to question if AMD had decided to try an old trick with the 7000 series, giving up hard-to-notice texture detail for a couple of frames per second in some games. We’re glad that AMD responded, clarified the situation, and provided proof in a fixed pre-release driver, plus a commitment to include that resolution in the upcoming Catalyst 12.4 WHQL driver. The driver it sent us for testing suggests that the issue can be solved without sacrificing performance.
As a tech journalist, it’s somewhat gratifying to identify a problem and then work with a vendor to get it fixed, and Tom’s Hardware has a rich history of this kind of investigative journalism.
I will say that I’m a bit surprised that the original findings we published in the Radeon HD 7870/7850 launch article didn’t seem to generate a significant amount of concern from our readers or the community. Toying with graphics quality is a slippery slope, and it should be something enthusiasts care about. Perhaps today's power users have more faith that these kinds of problems are nothing more than rare accidents that get fixed quickly and on their own. In this case, it appears the end result will probably mirror that optimistic expectation. But I think it’s important to stay diligent about defending the quality expectations we have of both AMD and Nvidia. Indeed, if Catalyst 12.4 goes live and the fix isn’t included, we’ll be the first to let you know.

lahawzel These differences are things that no one would ever notice if tech review sites didn't point them out.Reply
Well, not that I mind knowing that it can be fixed with a driver update, but I find it unnecessary for the average gamer to worry about these minor differences with image quality (knowing it's "fixed" is more of a placebo than an actual improvement of gaming experience). Not to mention that the typical gamer plays on 6-bit TN-panel monitors because "HURR 1ms RESPONSE TIME HOLY SHIT BEST SCREEN EVER" and they in turn elect to give up the superior color gamut and viewing angles conferred by IPS panels. They ought to the last ones who deserve to complain about image quality, at any rate. -
buzznut Huh, don't know about all of that but thx for the article. I do think its important to bring such things to the vendor's attention and follow up to see if they respond appropriately. Good job!Reply

therabiddeer Is it just me or is toms heavily biased towards nvidia? We see tons of articles for the Nvidia 6xx but very few for the 7xxx. Nothing negative for nvidia, but an article like this for AMD's, which is already being fixed even though it is undetectable... and the fix doesnt even yield a real change in framerates.Reply -

HAHAHAHAHA
Oh man that made my night. But yea, that's exactly why I just got a panny st30 screen, tn's are just garbage, and lcd just can't do black. As for framerate lag? Doesn't affect my average scoreboard k/d ratios, or lap times, or whatever other "precision" timing actions both online and offline.
Least I got a screen that can do my cards justice, this also makes me glad I got my crossfire setup with the 6780's instead of waiting for the 7000 series...

SteelCity1981 Nothing new really early driver support for new graphics cards always have their bugs, but normally by the 3rd supported driver version a lot of the generel bugs are normally fixed, because by then a lot more people own that card series thus giving a lot more feedback to the gpu company about the drivers suppported for that card.Reply -

Going from a dell u2711 2560 x 1600 to a asus vg278h 120hz 2ms tn panel, there is a clear difference in gaming. The u2711 compared to vg278h feels sluggish. The image quality, sharpness and color is clearly better in u2711, but the lag is terribly noticable.
Once you get a real gaming monitor, you will see the difference for yourself. TN 120hz monitors are the only true choice for pro gaming, imo.
