Texture Compression broken on GeForce Cards???

[2Whyzzi]

I stumbled across this little gem while snurfing around <A HREF="http://www.savagenews.com">Savagenews</a>. The site contains a link to an article from <A HREF="http://www.gamebasement.com/pages/home.asp?nav=articles&id=49">Gamebasement.com</A> about why the sky appears to be in 16bit colour when texture compression is enabled on GeForce Cards. It also talks about a performance penalty when implimenting the fix!!

I thought interested MURCers might want to know!

It's not a hardware problem. I'm tired of explaining why. If I find the explanation whilst cruising the web I'll think about posting it here mabye. sigh.

[superfly]

Bah....It's not like i need it anyways,i have 64 megs on my card,might as well use'em for something.... .

Texture compression is for girls! Brute force is good!

That can't be. I thought the GeFart cards were the next best thing since sliced bread.

IT IS A HARDWARE PROBLEM DOSFREAK!!!!1

From TheRegister:

"In the last few months I have run many test and benchmarks on PC video cards. Although Voodoo 5 is now, unfortunately, passing into history, my attention was grabbed by two cards in particular: the GeForce 2 and ATI's Radeon, writes Fuad Abazovic.

While many hardware sites and magazines have looked at these cards in some detail, Anandtech and a few other sites reported a problem with images of the sky in Quake III which posed some questions about DXTC (Direct X Texture Compression) on GeForce 2 cards.

Nvidia is normally fast and effective in fixing bugs and the results of my own tests suggest that there is some hardware problem here which can't be solved merely by driver updates.

One test, in particular, looks completely different on the GeForce 2 and Radeon platforms, and again it is to do sky textures.

The test, which is called the Dagoth More Zoological Gardens, was the first Transformation and Lightning test specifically designed for Nvidia. ATI's Radeon, which is as we all know is a T&L compatible card, produces a better image quality then the GeForce 2 on Nvidia's own test suite.

A few days ago I managed to capture some screens, which demonstrate the problems. And the shots are pretty decent proof that the GeForce 2 cards dohave a problem with DirectX Texture compression. ®

Alessandro:

While I agree with you, in principle one should avoid quoting from the Register. They are so full of s**t that their eyes are brown.

[alessandro]

Maybe i sould find the "Dagoth More Zoological Gardens" test to test it my self

[Gurm]

No no, it's ok since they were quoting another source. However, when what purports to be a news organization reports such things as "Killer Robots Poised to Follow Bill Gates' Orders", and "God Advertises For Apple"...

Well, you get the picture.

In the Register's defense, at least they admit that they're providing entertainment. Most other news sites have their heads stuck too far up their rears to realize that.

You can't get "news" from anybody, it's always a "story" instead. At least they make it humorous to read, sometimes intentionally, sometimes because stupidity is funny.

The problem is that whenever the register gets a "scoop", it's impossible to believe them because so much of their other stuff is unbelievable because... well... it isn't real.

You can either provide news, or provide humour. Not both.

I have been a Register reader for quite some time and never had any problems discerning the story from the punchline...*shrug*

Hey Rags,

Remember - you're smart. 99.99% of people are... err... NOT smart.

Actually the games developers have already comented on the article and it seems the problem is with the radion.

Unlike the Geforce,it doesn't support layered fog and that is what is causing the differences....
