Phoronix: Image Quality Comparison: Radeon Gallium3D vs. Catalyst

Coming up in the next few days will be benchmarks of Mesa 8.0 with Morphological Anti-Aliasing (a.k.a. MLAA) plus some other imaging-oriented work/announcements to come in the near future. With that said, this weekend prior to leaving for Munich I ran some tests of the Radeon Gallium3D and Catalyst drivers when comparing the image quality...

I like the FOSS enemy more.

on the purple bot (the second image) there is a redish cloud around the belly and the feet on the radeon driver, which doesnt appear on the catalyst. what is that? a bug, a feature?
and why is the crack on the floor on the first picture different when using the r300g driver?

a propos image quality
is there any news about S3TC and its alternative S2TC? would it be useful to have a performance comparison between them? IIRC S2TC was faster, but of lower quality.
-S3TC
-S2TC
-no compression
how about the legal side? maybe a short statement on ACTA?

will there be a quality difference with finished HiZ support?

I'm afraid there's also some apparent differences caused by using JPG images - the images in the article are all JPG.

Indeed -- normally you are only showing some glaring visual issues, and jpg is enough, but please consider using png when you are comparing different renders.

in my point of view the catalyst is just broken!

they only get more fps speed by hurting the image quality.

Its hard to say which one looks better because they both have good and bad aspects to my eyes at least

are you kidding? the catalyst only do have wrong colors on the "warrior" picture.

How do you know which one is "correct"? I use the open-source driver, but the Catalyst one looks better to me.. (not that you would ever admit that).

I personally tend to agree with Q on this one. Catalyst tends to be faster because it uses shortcuts, lots of shortcuts. It used to be even worse. I mean, back in the day, you could see glaring graphical differences between say ATI and Nvidia cards.
