    We could simplify the issue...

    basically, GPUs have a "switch" that activates the patented method (S3TC decompression).

    S2TC does not evade THAT part - it could, though, if S2TC decompression...
  2. They could only go after users of which they know...

    They could only go after users of which they know they use S3TC compression algorithms.

    I.e. only users who


    use runtime compression (as opposed to making precompressed textures with...

    The beauty of this approach is that mesa does not HAVE to accept it - it works as external library and the burden of supporting it or not is purely in the hand of the distros.
  4. Neither is, as not enough graphics chipsets...

    Neither is, as not enough graphics chipsets support them yet

    RGTC also is only suitable for normalmaps - it is "Red/Green Texture Compression" after all and cannot encode a blue channel. And LATC...
  5. You may be right, but Mesa already takes the risk...

    You may be right, but Mesa already takes the risk of passing raw data through.
  6. Forcing such an option enabled is certainly bad...

    Forcing such an option enabled is certainly bad style and I would not recommend anyone to do that.

    However, Xonotic itself already comes with a S3TC fallback - one I wrote that predates S2TC. It...
  7. Still, that suggestion was shot down by the mesa...

    Still, that suggestion was shot down by the mesa devs mainly for lack of support for software fallbacks, from what I see.

    With S2TC, software fallbacks would work - although at lower quality, if...

    And then wait for 5 years till commercial games for Linux start actually checking for it?

    The idea is otherwise not bad.
  9. I currently had no contact to the mesa devs yet.

    I currently had no contact to the mesa devs yet.
  10. This is correct. But, to upload a precompressed...

    This is correct. But, to upload a precompressed texture, you need the OpenGL extension GL_EXT_texture_compression_s3tc, which contains both compressing in the driver, and uploading precompressed...

    I am just explaining the motivation between US based software developers to follow US legislation, as it apparently isn't clear to some people here.

    It does suck that a bad situation in the USA...
  12. The author of Mesa, Brian Paul lives in Steamboat...

    The author of Mesa, Brian Paul lives in Steamboat Springs, CO, USA. If he makes Mesa violate US patents, this can cost him his (financial) existence.

    You are free to fork Mesa outside the USA, and...
  13. A Linux distribution not based in the USA, and...

    A Linux distribution not based in the USA, and which is not sold in the USA for profit, has no reason to follow US laws.

    Problem is, though, that many major distributions ARE based in the USA, and...
  14. It would automatically work, provided your...

    It would automatically work, provided your graphics card supports S3TC decoding. In case it does not, Mesa may implement it using S2TC decoding, but even if it will work, it will be slower. You...
  15. Actually, the preferred way would not be...

    Actually, the preferred way would not be including this in Mesa as ONLY version, but to continue to have support for the s3tc-enabled libtxc_dxtn.

    This can be realized for example by Linux...
  16. That is the general idea. The "world...

    That is the general idea. The "world implementation" is here:

    http://cgit.freedesktop.org/~mareko/libtxc_dxtn/

    However, US-based linux distributions cannot safely include that. I intentionally...

    Feel free to ignore the preceding post by MikeeUSA, who is clearly not representative of our community ;) you can google his name to find out more.

    First of all, Nexuiz is more similar to Unreal...
