Disappointing but not surprising. I thought it would fall apart with thin geometry and lo and behold it does. Thanks for those shots, they're precisely what I was looking for.

The new driver changed the default colour temperature. You'll have to recalibrate your screen.

Yessir. The reason I even bothered to try it was because using that spoof prevents you from enabling transparency multisampling, which is annoying. I wouldn't mind if I could afford to run 4xSSAA, but I can't really without it causing a bit too much stuttering in VATS (though I'm tempted to because 4xSSAA looks fuck awesome).

Sorry, I think this looks like shit so far. I've tried to play some stuff that's really bright so I can see the jaggies/blurs clearly (stuff like OutRun 2006 that has very high contrast), and compared to straight 4x MSAA it looks like mud on my 1600x900 screen. I like my PC gaming crisp, whether it's aliased or not, and MLAA isn't crispy.
A reasonable solution for games that currently don't work with MSAA or have serious performance problems with MSAA? Sure, it might be a good enough replacement. I don't see it replacing more traditional AA methods though.
Note: my opinion may change as I play more games. But even a glance at the Steam overlay with MLAA on makes we want to puke. :lol
EDIT: just a thought, too... I'm thinking there's going to be a lot of people turning on MLAA while still having their MSAA options set, and thinking that's how great MLAA is, when in actual fact they're just running proper MSAA then MLAA on top of it...

so i think it looks pretty awesome on Dead Rising 2 and GTA4, oh and Batman: AA.
it makes my graphics card scream like it's overheating or not getting enough power though, but that could be something more general about these drivers.

MLAA is one of those common sense things that's been running through my head for years. "Instead of doing all this AA sampling during rendering, why not just blur edges after rendering?" Obviously as not as simple as it sounds, but the results are showing some excellent promise. Loved MLAA in GoW3, hope someone manages to get it working on my 4770 (somehow). Hopefully with more work and refinement, both ATI and Nvidia will support it and we can do away with all of the overly costly forms of AA.

Need some before and after screens of GTA4.
Just like deferred rendering could be "backported" from DX9.0 to DX8.0, heh?TOAO_Cyrus said:
Without looking at the shader itself, I can't tell if it can be done in CS4 or not, but it's a given that CS5 is flexible enough that Intel's MLAA could be probably dropped on it without major changes in the technique (just like Sony did on the PS3's SPUs). Porting it to CS4 might, at the very least, require some re-thinking.
Anyway, at gamedev.net's forums someone came up with a DX9 MLAA-like effect (but it is more aggressive on textures), so they could go that route if they really wanted.

Anno 1404 MLAA
Hmm, looking at it again now that I am no longer sleep deprived, you may be right. Still the more important question remains; if AA with MRT is only a problem for DX9 as your OP suggests and the MLAA solution only works on DX11 calibre GPUs, wouldn't running your games in DX10/11 modes make this solution redundant anyway?brain_stew said:
Though going to see an optician isn't a bad idea. Haven't had my eyes checked in years despite the fact that my eyesight is very obviously weakening.
Here are my findings..
S.T.A.L.K.E.R.: Call of Pripyat - didn't work but really slowed the game down
FC2 - didn't appear to work
Anno 1404 - again, didn't notice a difference
Crysis - Didn't notice a huge difference probably wasn't working
Dragon Age: Origins - looked great.. liked this one a lot
Assassins Creed II - looked great
Tomb Raider: Underworld - good again
Based on that pic above, I'm going to have to test Anno again. Oh, I should mention that the 10.10 series of drivers really improves Crysis performance.

I have a 5870, I updated to 10.10 in Steam and then installed the hotfix from the link in the OP and restarted, but I am not seeing any option for MLAA, just the normal 3 modes that have always been there.
I also tried editing the registry entry mentioned in the OP to 0 but it was already set to 0
Any idea what i am doing wrong?

MLAA seems to work only with DX9.
Gonna try running Crysis with DX9 now to see if that's the case.

Might be a stupid question but did you reboot?SuicideUZI said:
Meh, I usually play all my games with no AA, so it doesn't bother me anymore. Quick question though for those in the know... when screen resolutions (and game resolutions) start get get higher than 1080p, will AA even matter anymore? It seems to me that the higher the resolution the less aliasing is even noticeable.

Blur is there but very minimum, Nice update ATI. Mite end up upgrading to 6,000 series instead of 460.

Yes... running Crysis in DX9 allows MLAA to work.
Looks GORGEOUS and runs a lot better, amazing job AMD.

tbh the negatives outweigh the positives for me. the hud/ui/ingame blurring is a huge turnoff.

I think it depends on the game, I play at 1920x1200 and some games without AA the jaggies stick out like a sore thumb, while others you have to pay close attention to notice them.
Either way I play at a high resolution and the difference between AA and no AA in general is pretty noticeable to me

yeah, I was trying to find it by just right clicking on the ATI task manager icon, didnt realize you had to actually go into CCC and check on "Morphological filtering"
it is kind of confusing because you'd think having application managed clicked would not use any AA from CCC, but if you uncheck application managed then its going to use whatever you AA mode in CCC is set to
It seems to be working for me in Starcraft II, but does not work at all in City of Heroes, think I will try Crysis next

I'm pretty sure that for now, MLAA is only working with DX9 titles.
Running a "MRT" game in DX10/11 doesn't automatically grant AA.Luigiv said:
1) These "MRT" games usually fill multiple buffers (render targets) with information other than colors, the most common being surface normals (aka: direction vectors) and depth (a distance value). This information is used in other parts of the rendering (depth can be used to apply fog, SSAO or depth of field and normals can be used for deferred lighting, decals, etc).
2) AA works by storing multiple colors for each pixel (the samples), which are then blended together to form the final pixel color which is displayed to the screen.
In DX9, the contents of a MSAA buffer can only be read after it has been "resolved" (aka: the samples for each pixel are blended together to form single pixels). So, if you render non-color information in a MSAA buffer and try to read from it later, the pixels at geometry edges will contain incorrect data: you cannot simply blend normals, depth or other custom data like you do with colors. Using this incorrect data will cause glitches on the edges.
DX10.1 and DX11 allow MSAA buffers to be accessed without blending the samples: the shaders can read the individual samples and work at sub-pixel level. This allows the shaders to read all samples of whatever data the buffer contains for each pixel, do the calculations, and blend the (color) results. However, this isn't free: MSAA buffers use more bandwidth (since they are 2x, 4x, 8x larger) and MRT rendering techniques already use more bandwidth than normal. Also, the same shader needs to run multiple times for a single pixel (on the edges). And all shaders need to be coded to make the MSAA work: it's no longer a simple flag the devs can turn on like MSAA was in DX8/9.
Now, it is very likely that upcoming DX10/11 games start packing their own MLAA implementations properly integrated into the games (without messing with UI).
