HD Screen kind of (by Enabling Floating Textures)

Have you try that?, Its really pretty cool, its like become your desktop in HD desktop, Now im trying again with Mesa 13.02 to evaluate my system with it.

I dont understand why distros's doent come with this feature enabled by default.., but it make a big difference, Its AMAZING!

Steps To enabled it:
0- Install S3TC library compression
https://dri.freedesktop.org/wiki/S3TC/
(libtxc-dxtn0_1.0.1-dmo1_amd64.deb) --> You can find package in deb-multimedia repositories

1- Download your Mesa version
ftp://ftp.freedesktop.org/pub/mesa/

2- Rebuild Mesa
You must rebuild Mesa with flag --enable-texture-float, like this for Intel graphics:
2.0

Code: Select all

./autogen.sh --prefix=/usr \
--enable-texture-float USE_EXTERNAL_DXTN_LIB=1   \
--libdir=/usr/lib/x86_64-linux-gnu/  \
--enable-gbm \
--with-egl-platforms=drm,x11 \
--enable-shared-glapi \
--enable-glx-tls \
--enable-glx \
--enable-osmesa \
--enable-driglx-direct \
--enable-gles1 --enable-gles2 \
 --enable-egl \
--enable-dri \
--enable-va \
--enable-vdpau \
--enable-xa \
--enable-xvmc \
--with-dri-drivers=i965

2.1 make, sudo make install

Lovely.

Because it's protected by patents I think.

What does it do that is AMAZING? Can you illustrate?

stevepusser · #3 Post by **stevepusser** » 2016-12-21 20:57

It's far better to rebuild the Debian mesa packages and just add that flag to the build configuration instead of doing that "make, make install (as root)*" procedure, which can have unpredictable conflicts with Debian packages.

* Hey, you left the "as root" off, please don't tell me you run as root because it's more convenient...

well, Its Amazing, cos the depth of textures is deeper, so the grapichs look more alive/real, its has bigger density.

I can see very well the difference it makes when play a 1080p movie with Kodi.., What i dont know, and i'd like to know is if VGA Output also bind floating textures, cos in my TV i didnt see any difference, or at least i didnt release about it.

S3TC library its , but you can use S2TC : a texture compression algorithm designed to be compatible with existing patented S3TC decompressors while avoiding any need for patent licensing fees (Im using S3TC of course

, but i dont know which one is better

).

Looks like its already enabled in Debian. http://imgur.com/a/lpdTS

stevepusser · #7 Post by **stevepusser** » 2016-12-22 05:39

Yup, actually implemented way back in 2011: https://bugs.debian.org/cgi-bin/bugrepo ... bug=635651

Debian also has the libtxc-dxtn-s2tc0 library for the S2TC compression, for what it's worth.

Yes, Its seem so, then the difference i see its with S3TC compression, it looks kind of better that S2TC, at least when playing HD movies. Anyways, also changed Gamma colours with s3tc library, to a more strong/alive calibration...

Perhaps by default, it doesnt work with external s3tc and you need own debian (libtxc-dxtn-s2tc0) to make it work, cos i had insatlled from long s3tc, and i omly saw it when building Mesa with flag's external lib : "--enable-texture-float USE_EXTERNAL_DXTN_LIB=1 "

Anyways you must install if im not wrong s2tc library to enjoy texture float.

I didn't need it for this, I just searched the online changelog for Debian's Mesa packages.

Ah, bester would never of done that 'cos he doesn't like reading.

From what I understand, 3D games may use the S3TC methods to compress texture data, so you need either the s2 or s3 library to decompress those textures and play those games. I couldn't find anything about it improving 2D video to any degree.

The sources also say that the S3TC patents expire in October 2017.

vbrummond · #13 Post by **vbrummond** » 2016-12-23 22:28

Placebo effect. Like the whole arch feels faster thing.

those are good news

I reviewed, and its not placebo, 1080p movie looks awsome with "Floating Textures S3TC" (The colour deepth its bigger than witout it, there the name "floating" )

or perhaps this:
the quality of S2TC is not as great as S3TC
http://www.phoronix.com/scan.php?page=a ... _fix&num=1

I think, you can check you have it installed this way:
glxinfo|grep s3t

Code: Select all

    GL_EXT_texture_compression_s3tc, GL_EXT_texture_cube_map, 
    GL_OES_read_format, GL_S3_s3tc, GL_SGIS_generate_mipmap,

Then it should be simple to show the difference between the two with a couple screenshots.

vbrummond · #17 Post by **vbrummond** » 2016-12-25 21:52

I would be quite happy to be proven wrong. My only reason for doubting you is the mesa packages are already built with this feature, so what changed?

phenest · #18 Post by **phenest** » 2016-12-25 21:57

You all seem to be discussing 2 different things here. The topic is about enabling Floating Textures but you're all discussing compression.

From what I understand, as stevepusser has already noted, enabling floating textures is for 3D rendered textures and not 2D, therefore video will be unaffected. See http://www.mathematik.tu-dortmund.de/~g ... ml#arrays3. So why the discussion on compression?

bester69 · #19 Post by **bester69** » 2016-12-26 08:10

i think i will atached some captures to try to convince all of you..

Sorry, i think we cant do this, this is hardware feature, I think you cant make a capture,cos you will see the same

, am i wrong?

Don't make excuses. Attach some captures so we can all see.
