TNT2 - DXTC/ S3TC extensions ..
 
Hi,

I try to play unreal tournament 2003 demo under linux but it hangs because of an error on missing DXTC/S3TC extensions ..
I don't understant .. It works fine under windows ..
There's no support for this with TNT2 under linux ? :\

no one can help me ? :|

same problem as you
 
I have readed that win version uses D3D, without S3TC.
In linux, only OpenGL is posible, and OpenGL uses S3TC.

I think we need to update our graphics cards :_(

Too Bad :~\

You need a fairly recent Nvidia card + latest drivers
 
Hi,
You have to be running the latest drivers and have at least a GeForce card. Am not sure whether any particular revision is required as I have a GF4.
The linux readme file in the ut2003 install directory actually mentions this particular problem and basically says:

"You need an nvidia card, and you need the latest linux nvidia drivers".

The minimum requirements for UT2003 are a GeForce 256 and PIII 600. Please check the UT2003 README for more details.

Nvidia TNT2 (pro,M64) are Nvidia cards.

But doesn't have S3TC, Gforce and up, have them

TNT/2 users will have to update our systems.
Also my PII needs an upgrade too

and My acoount need a lot of $$$!!!

At least, we can play UT3 in Windows with tnt2 ;)

...but it also says:

that it will run with '16 MB TNT2-class'.
Which doesn't have hardware T&L.

Why should that run on Windows but not Linux?

I thought that the problem wasn't the hardware wasn't good enough (although that may be an issue...) but i think i can throw together a libgl that can be preloaded that will convert s3tc into regular textures...
BUT!!!
I am pretty sure that would be in violation of US patent law and so unless someone has space on some webserver where us patent laws are ignored, i can't really post it anywhere :(

The TNT2 is supported under Windows through Direct3D. As Linux doesn't have Direct3D, you'll need to use OpenGL; this necessitates a GeForce 256 or higher card.

Thanks!

Well although performance may not be up to par, IF ut2003 didn't use s3tc then it should run on tnts... my point is that its pretty trivial to bypass the libGLcalls to load the compressed texture and simple decompress the s3tc then load the texture. This (i believe) would be in violation of s3's patents on s3tc. But I can't seem to find the patent numbers on s3tc(or dxtc whatever you wanna call it)...

Ah. Thats along the lines of what I was thinking... if DirectX can do this decoding in software, OpenGL should be able to.
And I'd have thought those that work on the linux OpenGL libraries would have gotten around to putting it in by now, if its not too much work...?
