interesting facts about radeon and geforce 3 anisotropic texture filtering

[flexy]

Edit:
The below might be a bit technical....but it all can said in short:
One major drawback of the gf3 is the fact that textures become blurry compared to radeon 8500 if certain texture filtering methods are usedd. However....there is a hidden registry setting for the gf3 to enable high-quality filtering and getting rid of the blurryness of textures !!!


i was just on www.rivastation.com (in german) where they had a very good review about the radeon 8500 in comparison to nvidia geforce 3 ti 500.

What most people rave about now is the capability of radeon to filter/smooth textures at higher frame rates compared to geforce. There were some pictures on the site which explained that very well.

One reason the radeon does not drop significantly in fps (if you switch on high level texture filtering) is, that the radeon uses dymanic filtering....eg. there are texture filterig methods called 16tab, 32tab, 64tab. The higher the value, the BETTER the picture quality. 64tab=best quality and (of course dropped framerates.

Radeon does this dynamically based on the contents of the picture...eg. it would not use 64tab all over a frame/picture...but only there where its needed: Result ---> its fast !

The * interesting * thing now is that the people on rivastation say that GEFORCE 3 has the texture-filtering modi 16tab, 32tab and 64tab. 64 tab equals the highest quality (even SUPERIOR to radeon in terms of picturequality if it comes to texturefiltering...you can see the pics on rivastation)....

Interesting is, that Nvidia has NO offical support for the highest quality 64tab filtering setting in their drivers (however, they're said to think about implementing that now).....but you need some tweak tools like nvmax etc. to enable the 64tab texture anisotropic filter for the Geforce !!!

I think this is very interesting. There is a hidden feature which brings out superior picture/filtering quality...and it's not officially supported AND you cant find in in the drivers....and maybe not many people know about it !!!!! (I didnt know about that either 'til half an hour ago

If you switch/tweak on the 64tab texture filtering on a gf3 with the nvmax tool...than you can of course expect some less framerates than on a radeon, since the gf3 does the filtering ALL over the frame...while radeon uses it's dynamic method and has less to compute.....but in terms of quality the geforce is superior !

(I found that article very interesting)
