    Exclamation AMD 7000s: Texture quality problem confirmed & fixed

    I personally don't trust Toms' Hardware, anyway here it is: LINK

    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?When we were testing the Pitcairn-based Radeon HD 7800 cards for last month's launch, we stumbled upon image quality issues with AMD’s two most recent boards. Specifically, we noticed textures in popular games that appeared blurrier on all of the Radeon HD 7000s compared to the prior-generation offerings. And this was using identical image quality settings in the software driver and the games we were testing.
    From page #8:

    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.
    From page #7:

    With a pre-release version of the fixed driver in hand, we went on to see if AMD's solution solved our problem without negatively impacting anything else. First, let’s look at the texture quality results:
    Excellent. The new driver fixes the texture blurriness issues. And, at default settings, the Radeon HD 7870 series textures appear at least as crisp as the Radeon HD 6970. This is very good news indeed.
    Thankfully, performance seems unaffected by the fixed driver and accompanying image quality improvement.Finally, since AMD claims that its problem was the result of an anisotropic filtering technique, we thought it would be a good idea to compare the output. Does AF suffer because of the driver fix?

    Anisotropic filtering is identical between the Radeon HD 7800 launch driver and the beta driver AMD sent to us. The 3DCenter filter tester appears to produce the same output on the Radeon HD 7870 with either driver, while the Radeon HD 6970 demonstrates inferior filtering compared to the 7000 series. Even when playing back video of the tunnel test, we couldn't notice a difference in shimmering between the launch and fixed driver.

    So they publish an article with solid proofs and AMD also fixes the said problems...are you start off with "toms hardware is not trustworthy"...nice.
    The abuse of greatness is when it disjoins remorse from power.
    Please do not PM me for support. You will NOT get a reply. Post in the relevant forum section.

    @ .. CvP,
    Lol; I never said all of their article are false. But, I don't usually trust them. It's an exception, that's why their proofs better be true.

    Tomshardware is hated by many, its notorious for its biased reviews. That said sites like Guru3d have a better reputation.
    FTW!!!!!!!!!!

    Launch drivers so we should let this slide. Glad that they fixed it though.
