Morphological AA for Radeon HD 5000 series coming soon

The morphological AA feature introduced with AMD’s Radeon HD 6800-series graphics cards is an intriguing way of adding anti-aliasing to the unfortunate torrent of games cross-developed for consoles that simply don’t work properly with conventional multisampled AA.  We looked at it briefly in our 6800-series review, and I’ve been playing with it some since then. Preliminary verdict: it ain’t perfect, but it’s way better than the complete nothing you often get in current games. MLAA as AMD has implemented it is also superior to most of the console-style post-process filters out there.

Making it work has been a bit of a trial, though. If you own a Radeon HD 6850 or 6870, you’ll want to grab the latest 10.10d hotfix drivers to sidestep a bug that caused the feature not to work in some games.

Owners of Radeon HD 5000-series cards don’t yet have the option to enable morphological AA in the Catalyst Control Center, but we just received word that AMD is preparing another hotfix driver release for next week that will allow MLAA on those cards. If you have a Radeon now, you’ll want to grab those drivers when they come out.

The performance hit for MLAA can sometimes be steep, but faster GPUs won’t have a problem with it in many games. I’ve had good results in Medal of Honor‘s single-player campaign, for instance.

We also understand that AMD is working to improve MLAA in terms of both image quality and performance. Since the effect is generated by a post-process compute shader, the potential for refinements going forward could be considerable.

Update: Turns out the release of this driver may be closer than we’d anticipated. Stay tuned!

    10.10e with 5xxx support.

    I’m fairly sure the hardware can’t do it but it’d be neat if they managed to get a form of this working on the 4000 series as well. 😛

    You can already hack the 10.10a/c/d and get MLAA on 5xx0 cards.
    §[<<]§ It works flawlessly on my 5750 and if you have the latest beta of Ray Adam's ATI Tray Tools, you can have MLAA per game profile. §[<<]§

    It’s just a quick edit of the 10.10d drivers to get it working on the 5-series. Played through Fallout:NV on my 5850 with 8xMLAA and the performance is massively better than MSAA, though image quality slightly poorer.

    Poor Nvidia fanboy. Lol

      Couldn’t possibly be a sarcasm detection failure this epic… could it?

    If this can be added to the 5800 series, then that means it’s just a shader. That means, something equivalent can be added to nVidia’s cards, too. It’s funny how when ATI tried to sell people on shader-based AA previously (2600 I think?) after their hardware AA component WOULD NOT WORK, the review sites were up in arms and rejected it.

    However, THIS is acceptable. Hm. Can’t wait till nVidia slaps it into a driver, calls it, “nVidia SurroundPixel Blurmapping Morphmending Game Enhancement” and then show how it is superior to AMD’s version because it can detect when a texture is not being properly blurred to hell and offer an option to “Enhance Blur Levels” by 2x, 4x, 8x, 16x, 200x.

    Cue the nVidia intro vid! “EEEEEN-VIIIIID-EEEEEE-AAAAHHH!”

    At least they are not forcing users of the 5000 series to upgrade their cards to get this feature.

    My 5770 waits patiently for the update 🙂

    This is awesome.

    Cool, though I already got the impression it should have worked with 5000 series.

      I believe they mentioned there wasn’t a technical reason it couldn’t but that it hadn’t been implemented.

    Nice! I wasn’t expecting that they’d do this till after Cayman at the earliest, kudos AMD.
