Shadermark banding

[Ante P]

Could someone just run shadermark on a R3X0 board and look if they get the same banding as me:

You can see which test I ran up in the left corner.
jpeg compression made it look a bit better though.

Same here on my R300. . .

good to hear!

How about this in 3DMark...

The paranoia begins...

Hi Mufu,

My eyes arn't so good, what's wrong with that 3dmark shot?

You can't see any banding, or do you mean that matches the reference image?

Heh... might be a limitation of this LCD actually. Hang on - I'll check on another PC.

I think I can see a hint of banding, but the pic is so small damnit

Where do you see the banding? The picture doesn't give me enough room to see it. I'll try real hard.

I am used to viewing a 19" samsung LCD, so perhaps it's just my eyes arn't used to looking at a now horribly blurry looking CRT.

I'm not seeing any noticable banding as far as I can tell, but that image looks fairly dark on this monitor so it could be a difference in gamma. I'd have to say at this point though, I don't notice anything specifically wrong with the image. Do you have a reference image we could compare it to?

Yes, next to the shadow I see what seems to be a few lines separating darker and lighter shaded areas. Why is this artifact present?

 

[MuFu]

Appears the same on CRTs w/a 32-bit display mode - I checked on two other PCs.

I can see at least 7 intermediates between the dark area under the small table and the lightest area as you move right across the picture. Monitor is a Samsung 172W via DVI.

I have no idea why it appears that way, hence me posting the pic.

Mufu:

Now that you've pointed it out, I can see what might be *very* subtle banding on this CRT, but I wouldn't have noticed it if you hadn't said something. Do you happen to know what gamma/brightness settings you have on the two monitors/lcd? I'm not sure about this monitor, I'm guessing it's probably pretty bad, which might be why I can't see it as well.

I'll let you know later tonight how it looks when I get back to my samsung LCD.

No ideas about the other monitors - on this it's just one of the preset brightness modes ("Internet") with the 172W *.icm loaded and the default gamma settings. I am quite suprised the banding isn't very clear to other people. These are the edges that PS finds...

You can see them in that pic, I hope?!!!

I can see them in both pics on my LCD.

Mufu:

er...

I can see the outlines of the shadows very clearly in that pick, and I can see the multicolored patterns on the ground plane, but still can't see the banding well. I think your right in that it's there, but not very visible on this screen.

:?

Perhaps I'm going blind?

i'm in the same boat

stop posting mini-pics

run the test in 2048x1536 and then crop it

I too see what's in question (even with running 3dmark03 on my r300), but it is not clear that it is banding. It could just as easily be other shadows that aren't completely drowned out by the lights (but almost). Anyone with the full version care to run it through the reference rasterizer?
