ATI texture filtering quality? Shimmer this! Sep 08, 2005, 09:30 AM

By: Sander Sassen

Throwing fud back and forth is not uncommon in this industry, many manufacturers do it to put their product in the spotlight and make it appear to do a lot better in terms of performance or features than the competition. ATI and NVIDIA have both been doing their fair share of fud throwing, but it usually is ATI that goes out of its way to find fault in new NVIDIA products shortly after launch. So we weren’t surprised to be notified by them of a texture filtering quality issue with NVIDIA’s top-of-the-line GeForce 7800 GT and 7800 GTX graphics cards.

Upon closer inspection there indeed was an issue with the texture filtering algorithm used in the 77.77 drivers of the GeForce 7800GT and 7800 GTX. This algorithm is said to up the performance, but lower the image quality as it causes for texture shimmering. Unfortunately it isn’t easy to reproduce this ‘shimmering’ as it appears to vary from game to game and system to system, with some games appearing fine and some clearly having issues. That being said NVIDIA was on the ball quickly and resolved the issue in the 78-series drivers that were launched last week.

So to our surprise we found out earlier this week, and as reported here, that ATI’s Catalyst 5.8 new drivers have the exact same problem. And unlike NVIDIA, that was on the ball immediately after reports of texture filtering issues with their newly bought GeForce 7800 GT or 7800 GTX, ATI doesn’t even list it in the release notes for their Catalyst drivers. Normally these new releases are accompanied by release notes that describe bugs that are still unresolved and are being worked upon, the texture filtering issue however isn’t mentioned. So did ATI code this in as a feature to up the performance? Was it simply a bug that got in somehow? Or is this a case of the pot calling the kettle black? We’re waiting for ATI’s reply on this, and whether they’ll be on the ball just as quickly to resolve it. Or will we have to wait another month for the next Catalyst release?

E agora, onde está o escândalo que a ATI criou com o bug nos drivers da Nvidia 77.77 e 77.76 ???
LOL.
 
É por isto que tenho uma 6800 Ultra e não uma X800 XT PE.

Infelizmente ainda não tive nenhum aumento milagroso de performance como aconteceu na gama TI mas a placa ainda é francamente recente :D
 
Última edição:
Sempre gostava de ver o pessoal que crucificou a Nvidia na thread da 7800 vir agora aqui comentar esta notícia ...

"Ah e tal porque usam cheats ..."
 
The issue seems to be most apparent in Half-Life 2 and Counter-Strike: Source and we can confirm that we've seen the problem too. Last Thursday we spent a large amount of time evaluating the image quality of Catalyst 5.8 on the Radeon X800GT after seeing some irregularities.

However, at that time we were not 100% sure that we were seeing shimmering, as the uncompressed videos that we had recorded with FRAPS were not showing what we were seeing in-game to quite the same extent.

Um jogo tem um bug nos drivers, que nem sabem bem se é shimmering. Que não existe nos 5.7

Parabens aos fanboys presentes.

Está descoberta a principal diferença entre ATI e NVidia: vocabulário.
Em NVIdiês diz-se "cheat" em ATInio diz-se "bug". 8o
 
The issue isn't raised under the 'Known Bugs' section of the Catalyst 5.8 release notes, so we don't think that it's a known bug.

Isto significa que o "bug" não existia nos Catalyst 5.7 apareceu depois como "por magia" nos 5.8...

Yeah, right.
Keep your head in the sand :rolleyes:

Eles acharam que depois da bronca com a Nvidia podiam fazer o mesmo sem que ninguém desse conta, pois a tempestade já havia passado. (o mais engraçado foi terem sido os fanboys da ATI no Rage3D.com a encontrar a batota)
 
Eu não digo cheats, digo incompetencia perante uma situação que se arrasta ha meses em variados jogos, na qual a nvidia se esteve a lixar para os seus clientes.

Mas é engraçado como alguns deliram com estas coisas.
 
Meses ? Quando é que foram lançadas as 7800 GTX/GT e os drivers 77.77 ? Experimentaste os 78.01 ou 78.03 ?
E há quanto tempo existem os Catalyst 5.8 ? :rolleyes:

Parece que o Reality Distortion Field também já chegou aos fãs da ATI...
 
ahhh ok o problema não vinha do tempo das 6800... um pequeno lapso de memoria deve ser de tanta areia a volta da tua cabeça.
 
só umas palavras: blastarr no seu melhor...és um fanboy de primeira e desde que chegaste ao forum crias guerrinhas atras de guerrinhas, guerras essas desnecessárias que muitas das vezes tornas espalhafatosas...enfim, deve ser falta de atenção...
