R420 IQ Comparison

[Chris123234]

I really can't see a difference no matter how hard I try, is there any really obvious examples of the difference? :|

Yes. On the second one with the missing grass. In the middle of the page, on the very left hand side there is a triangular section or something like that where it changes when the wall meets the ground.

That bit on the left looks like more vegitation to me.

If people are convinced there are differences in certain areas , then you now have a couple of reference images and you can do you're own bit-wise differences to confirm it and post the results.

Or am I being dense again

If you have a ATI card then you have seen it in motion and guess what...for the last year ATI has won the IQ contest using it. Give your head a shake.

If you're commenting on what I said; yes, i do have a 9600pro, but no I do not have an nVidia card and oddly enough I dont know anyone who does so I cannot see any difference since I only have one perspective.

My original point remains. While ATI advocates demanded that nVidia be judged on motion captures they are now completely satisfied with screenshots when the issue is reversed.

Its difficult to get other points in UT because you have to alter maps so there is only one respawn point, and I'm getting help with that (thanks JB!!).

If its ok with Dave, if you guys have a couple of places in UT2k4 that you can see more of a difference then I can tweak the map for Dave. And yea even though I code for UT2k4 I don't know them all well enough to have a good idea...maybe some of the ONS maps??? Best of to email or PM me the location and map as I may not be watching the forums closely..MSU contest deadline coming up

Has anyone seen any significant differences in the shots in the places Malfunction has highlighted? I've ramped up my gamma and can see nothing different except for the odd pixel. I guess I must be a blind fanATIc.

The only diffrences i see in malfunctions pics is caused by the lights missing from the scene .

If there is hardly any difference in the pic then there will probably be hardly any difference in motion. nVidia difference was blatantly obvious was it not? Therefore it would be blatantly obvious in motion.

Would there be any reason UT2K4 would be more advantageous than Wolf:ET, other than Dave maybe not having the latter installed anymore? Because it would be relatively simple to replicate a screenshot location in Wolf:ET by simply recording a demo of you standing in place for however long it'd take to capture a screenshot. Perhaps you could do the same with UT2K4 (start your own local server, record a 5-10s demo of you standing in place at an ideal IQ-comparison location, then play that demo to grab screenshots)?

And we have a winner!!! Great idea man.

 

[StarGazer]

Just download some old demo and grab some screenshots

 

[tEd]

I hate to be a PITA but while those shots like fantastically similar, could you do one with a bit more range ? Both of those have limited scene depth.

Yeah, I know. Like I said, these images are close to ones that I've used before, and chosen because you can see the mip transistions in the detail textures in the bottom quarter of the screen. Its difficult to get other points in UT because you have to alter maps so there is only one respawn point, and I'm getting help with that (thanks JB!!). I've now got some CoD saves, but realised that I've lost Disc 1 so I may not be able to use the single player exe for now.

how about providing some movies ? With fraps it works quite well , try halo for instance it's a good measure for trilinear filtering

UT2004 has an OpenGL and Direct3D renderer, so if you wanted to see if there were any differences between APIs, all it takes is a switch -- no new demo needed.

 

[Pete]

Good point. Plus, UT2K4 should have more demo launchers to make for quicker capturing.

sorry...

Oooo, I couldn't possibly do that - apparently, according to some, just ptoviding screenshots is "going out of my way to disprove [ati of]anything", lord alone only knows what they'd say if I provide movies of it as well.

Seriously, I think FRAPS needs to be registered for that functionality, and I don't have a reg'ed version. What format was FRAPS captured in?

HAHAHAHA!!! Time for me to go home now. Spending too much time refreshing the B3D page.

 

[aaronspink]

Malfunction I see what you are referring to. The R420 image looks slightly blurrier on closer inspection in that region. My post above however is how I still feel. The difference is very small but I accept it is there.

Everyone should cool off a little though.

Wow I think it's time for Lasik. I don't see jack

Well there are some obvious pixel shift differences, but they shouldn't be cause by any filtering.

The un-rolled over image in that region is slightly crispier than the rollover image.

Dave you can do it with the normal fraps unregistered.

Score... lol

Before getting headache while switching between the shots for over 30 minutes, I found some areas, where R420 provides shraper textures, and I'm still missing those hard transitions I was seeking for. If this is the result of an optimized trilinear, I'd prefer to call it a genius one.

Anyway, I'd like too see both filters at motion. That sharpness might cause negative effects there.
