Anyone can upload a binary/compiled version of last LLVMpipe/Softpipe from Mesa3D 11.2.0 ? (sw "opengl32.dll" ) I'm trying to do it by myself but I encounter a scons error :/   And hey, now Mesa3D go

But disabling the compression (THAT particular entry in darkmod.cgf) doesn't solve the problem.

Right. We would need to ship uncompressed versions of all our textures. I think we had a package like that a long time ago but it would

be quite a project to scrounge all the textures in our repositories for the originals and some were donated pre-compressed so we would need

to convert them back to uncompressed formats.

 

No chance of adding S3TC to llvm soft-pipe?

No: https://dri.freedesktop.org/wiki/S3TC/

 

S3TC support has been partially implemented in Mesa. We cannot integrate and enable S3TC code by default due to the patents on the algorithm. Because of this, to be cautious, code was integrated to only attempt to open an external library, libtxc_dxtn.so, and use a small number of functions from that to implement S3TC if available. There is also an option in the S3TC-supporting DRI drivers called force_s3tc_enable. If the library is unavailable, setting this option to true will expose the extension even though it cannot be fully implemented. This may be of use for some games which require S3TC or don't use the ARB_texture_compression extension correctly.

Nice, REALLY NICE, improvements with lastest version:

 

16->28 ! (if only we could use LLVM 3.9 but we are stuck to 3.7.1 due to the missing LLVMipa in 3.9!)

And Unreal (OpenGL 2.1 unofficial patch, 1280x960) @50 FPS (!!!)

It's outstanding! (the renderer is recent)

Quake 2 with R1Q2 renderer (original one is wrapping-protected!)

If only they could add the S3TC support and a form of Anisotropic Filtering we're good to go :D OpenGL 1.x and 2.x unbound (NVidia, AMD and Intel :P )

If you're interested here's the lastest binaries build by MSYS2 project :)

 

32 bit OpenGL32.dll -> https://sourceforge.net/projects/msys2/files/REPOS/MINGW/i686/mingw-w64-i686-mesa-13.0.2-1-any.pkg.tar.xz/download

64 bit OpenGL32.dll -> https://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/mingw-w64-x86_64-mesa-13.0.2-1-any.pkg.tar.xz/download

 

Just extract the DLL and drop it in the main-exe dir of your OpenGL application.

If you're interested Mesa dev removed the LLVM 3.7 dependencies and now you can compile LLVMpipe with the shining new LLVM 3.9.1/4.0! :D

And with Mesa 17 the performance goes up again, 60 FPS in Unreal+OpenGL 2.1:

64 bit for old OpenGL games/engines is a non-sense. There's no old 64 bit OGL application (the first is Rage64) :D

Use normal 32 bit instead.

Its not only for old games i have intel gma with ofical 1.1 OpenGL only i need recompiled Mesa 3D 17.0.0 for windows 32/64bit any of them will be good.
But i can't handle to compile it myself, can you upload it for me somwhere?

I don't have a 64 bit OpenGL application installed to test the result of the build process!

Found a S3TC standard implementation in CygWin archive.

In theory mesa opengl32.dll + dxtn.dll = complete S3TC support in OpenGL 2.1

Unfortunately Mesa codebase makes clear distinction between Cygwin and Win32. Additionally libtxc_dxtn source code does not include a sconscript so Visual Studio is not an option. The only option left is Msys2 cross-compilation and with this, things go bad,

Compilation fails.

Me and another guy we found a dxtn.dll working with Mesa as you can see in the screenshot.

The main problem is the performance now.

      I posted about it before, but I think the default tdm logo video looks outdated. For a (i.m.o.) better looking version, you can download the pk4 attached to this post and plonk it in your tdm root folder. Every mission that starts with the tdm logo then starts with the better looking one. Try for example mission COS1 Pearls and Swine.

      I finished DOOM - The Dark Ages the other day. It is a decent shooter, but not as great as its predecessors, especially because of the soundtrack.
