It was on the shadows too, they were the worst offenders.
Well, in FC2's case, it looks very different from the dithering seen in GTA4. These shadows actually look interlaced of a sort or as though there is no interpolation occurring resulting in missing lines.
Interesting. I think I'm going to agree with your AA suggestions, only in the case of the 360 the AA is applied and then the shadows are drawn, which could make sense if the AA is done in EDRAM and then the shadows in the final pass when the image is out of EDRAM again (you may in fact, laugh at me if this is a stupid idea). In fact, I'm thinking this achieves 4xAA on the 360, but this is masked by the shadows (seem to be not using transparency).
I'm thinking the PS3's shadows are drawn in the exact same way, but then the PS3 version relies on the Quincunx to get rid of the pixellation of the shadows. You can see this in the bits that are only very lightly shadowed, or are single thin shadows, where you can still see how the original pixel pattern on the 360 is the same on PS3 but mostly positively blended into the background by the full-screen Quincunx.
The advantage of this seems to be that when a shadow is added to another shadow, this looks very nice and is an effect you probably couldn't afford to do with transparency (which is apparently expensive on either system). But then they probably either couldn't figure out how to AA the shadows in the 360 version without taking the AA out of the EDRAM, or just didn't have enough time to figure out a different rendering method on the 360 to take the shadows into account.
It is refreshing to see a third party use Quincunx on the PS3, and use it cleverly, although downsides for multiplatform development are also apparent, and you do get a slightly more blurried image in which texture definition suffers somewhat. Definitely both images are 720p though, no upscaling.
Does this make any sense at all? I know everything I know about rendering from these forums, so no claims of authority on my part.
Hopefully someone with more authority weighs in.Makes me want to try the game out though!
It looks like the shadows aren't filtered. The same crap you can see in Battlefield 2 or NFS Most Wanted on every older Radeon (because of lacking PCF support).
BF2:
WRT Most Wanted, you mean when the shadows are cast across a vehicle right? Because on the ground they were properly filtered IIRC (Radeon X850).
Ah okay, nevermind then, I thought you meant the MW shadows looked like the ones from BF2. :smile: For reference, I was talking about this, using one of the shots from your link: when the tree shadows are cast across the red car in the centre of the screenshot, the shadow "edges" are sharp whereas in the ground they are soft.

just dled Super SF2 HD Remix
http://www3.telus.net/public/dhwag/SF2HD1080P.jpg
there seems to be some kind of dithering artifact going on around edge of characters at 1080P
http://www3.telus.net/public/dhwag/SF2HD720P.jpg
seems smoother at 720P, but with of course, a lot less details
could this be a bug?
PS3 version BTW

The shadows are nasty looking, I noticed that when I played the game, I have a 100" screen currently and at that size the shadow artifacts look pretty bad. The X360 version is sharper and draws more on the screen though.
I have a question about Quincunx AA, a lot of PS3 titles use it eg TR:UW, Quantum of Solace, Assassins Creed, Resistance 1 (2?), and even Killzone 2.
Wheras basically no 360 titles do, is this due to architecture differences on the PS3 (eg SPE's) that make it more viable? Or are devs simply more interested in reducing aliasing in their PS3 titles these days, given the traditional lack of AA in PS3 ports.
As I understand the storage cost is the same as 2xMSAA, but the perceived effect is higher (eg =4xMSAA) but it blurs textures.

Quincunx is incorporated in hardware in nVidia graphics chips.
Here's Street Fighter HD Remix on 360. There is something a bit odd at 1080p... almost as though the art has been vertically scaled - badly.

So the game is suffering from that at 1080p on both consoles? PS3 and Xbox 360?
And what about the black bars at the left and right side of the picture of your screenshots grandmaster? Is the game pillarboxed?
If yes, what could be the reason for that? To compensate overscan of some displays?
But why at 1080p, too then? Most 1080p displays should support 1:1 display.
Strange.

The 360 download is around 380-390MB by the way.
That's a little interesting, usually the PS3 file sizes are larger...
Well then it probably shouldn't be the source material/art - the PS3 is 303MB apparently.
A poorer scaling algorithm, but at the same time, the image isn't blurred... a curious trade-off. Looking at the 720p shots closely, it seems the problems are still there, but are amplified (more noticeable) at 1080p. :s Perhaps a problem with the sprite technology they're using?
The environments appear to be fine (and even sharper than 720p upscaled to 1080p using a lanczos filter), so they're likely drawn at 1:1 pixel ratio.

That doesn't really look like the X360 version of Far Cry 2 though, which shadows look like they are rasterized.
