Can a 9600 and hopefully a x800 user please run this for me?

Okay folks here is my first test. If ATI is telling the truth some nasty stuff shouldn't basicly brilinear shouldn't be enabled for this test.

http://www.lexicon.net/mccann/BiBrilTriTest.zip (500ish K).

Now what to do.

First up the texture detail and mip map detail to the max.
Next apply the changes.
Next go to the d3d setting and force 2x AF with preformance.
Next apply the changes.

Okay now run the application and take a screen shot (alt-printscreen don't remove the title or anything. Oh and don't resize the app after opening it ) and save it as PNG and put on the internet and link here :).

Now Next go to the d3d setting and force 2x AF with quality.

Okay now run the application and take a screen shot and save it as PNG and put on the internet and link here :).

Thankyou very much for you time.

Oh and yes I stole code from some tutorial place I'll give code credits later.
 
I have screenshots (Mobility 9600), but no webspace. What's the difference supposed to be? The screenshots only differ at the top where the texture goes white. The "difference band" is about 25 pixels high, the rest is identical to the last bit. The performance screenshot shows a sharp edge from checkerboard to white (the edge is a bit curved, and blocky, i.e. quad-aligned), while the quality screenshot shows a smooth transition there.

Cat 3.7 is it, IIRC.
 
I've got a picture of it with the "high quality" mode, but I have no hosting. PM me if you'd like it in an email.

EDIT: It's with a X800 Pro

I am guessing that V-tec didn't change settings correctly. /shrug

There seem to be some rather large windows poping up from some people. I asume there was a point to asking not to resize the app. It will also reduce bandwidth usage. RTFM :)

So bloodbob, any conclusions yet?

It was supposed to be 800x600 I thought that would work at any res.

Okay I'm still downloading the PNG's I'm on dial-up but it looks like ATI are doing something dodgy on the X800 as you can see the at the TOP the colour is incorrect.

Now I was planning on trying to make a D3D wrapper like colours has made for a couple of things to disable the ATI-linear but it looks as if it can not be done on a X800 should work on a 9600 though.
 
Okay I've worked out what was going on with jimmers he used 16X AF. Only one of the trilinear shots had significant difference though this did not appear to be mipmap related it looked more like the co-ordinates where slightly different this could be a driver or AA related matter ( forced AA might have done it ). I'll upload a png of a screen shot on my pc so you can compare it to one of the samples.

So what does this all mean? it means ATI hasn't lied about this
It only applies this optimization to the typical case - specifically, where the mipmaps are generated using box filtering.

How my test worked. I used a black and white checkboard texture which was scaled with a power 2. With the standard mip-maping process the mipmaps are auto-generated with a box minification filter. 3. By choosing a point filter on a power of 2 checkboard means that once the mip maps get to a certain level the mipmap will be pure black or white as opposed to grey this is a significant difference and would be cleary visible. 4. If the image had grey at the later mip-map stages it would mean ATI are overiding the mip-map generation where the user hasn't explicty generated the mip-maps by themself. 5. It was also hopeful that any bri-linear would show up but I can't say this test is totally conclusive about that though it appears bri-linear has been disabled.

This is nice for developers who whish to disable ATI's optimisations :) they can explicty choose another filter for mip-map generation but point filters suck :/ but their is another really nice filter which is the Triangle filter or Tent filter this will have a slight load time cost but once the textures are loaded it will no longer impact the preformance ( well other then disabling ati's optimisations ). I believe this won't help users of OpenGl I could be wrong ( if it doesn't help the developer can still calculate mip-maps in the program and then load them with the texture but it won't be auto-generated ). If I get around to it I'll try to create a wrapper which forces Tent filtering of DX9 Apps.

Thanks to everyone who helped me out.

Does anyone else find it a little humorous that in the difference shot, the two cards show more of a difference rendering windows than they do rendering the 3D portion?!

Those are windows themes that are making the windows different. HAs nothing to do with the card.

I just realized I had at ATi 9600 Pro so I guess ill run them if i get around to it. lol

Ahh my bad, I had already seen the shots from the different cards so I went straight for the difference one. Well I guess that'll teach me to jump to conclusions.
