This allows SIMD16 mode to work for a lot more programs. Texturing is also more efficient in SIMD16 mode than SIMD8. Several messages don't actually exist in SIMD8 mode, so we did SIMD16 messages and threw away half of the data. Now we compute real data in both halves. Also, the SIMD16 "sample" message doesn't require all three coordinate components to exist (like the SIMD8 one), so we can shorten the message lengths, cutting register usage a bit. I chose to implement the visitor functionality in a separate function, since mixing true SIMD16 with SIMD8 code that uses SIMD16 fallbacks seemed like a mess. The new code bails on a few cases where we'd have to do two SIMD8 messages - we just fall back to SIMD8 for now. Improves performance in "Shadowrun: Dragonfall - Director's Cut" by about 20% on GM45 (measured with LIBGL_SHOW_FPS=1 while standing around in the first mission). v2: Add ir_txf to the has_lod case (caught by Jordan Justen).

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
