Can you still get on a Pure server?

So this means you can have S3TC turned on but the sky looks fine? What about the other textures? What do they look like?

 

[Vrangel]

The sky looks fine with TC on.

No problems with pure server.

woohoo! altho i am a radeon user good for you all my geforce brothers

Heh, they say its a hardware bug in GeForce chip.
Someone found a workaround.

Its not a hardware bug, its Q3's fault. It allows lightmaps to be compressed which causes the problem. ATI also uses S3TC but they dont compress 128x128 textures as a cheap workaround for the problem.

Quote from guru3d:
"It seems like GF/GF2 use 16-bit texels after DXT1/S3TC texture decompression (that's why sky into q3 looks so ugly). I don't think that it's a drivers' problem, I almost sure that it's a bug into NVidia chips. If it's really hardware problem, software developers must use other compression formats (DXT2-DXT5 or S3TC with alpha) to avoid ugly banding effects like sky into Q3".

Patch forces DXT3 instead of DXT1.
