Compiled LLVMpipe/Softpipe for Windows

I posted the next release 17.0.1.391-2 with S3TC support. It should be live in a few minutes.

Thanks man!

Voilà! 1-2 FPS

 

@lowenz, you have complained about poor performance with S3TC, If this is a 32-bit game, this S3TC DLL might help as it does not require cygwin runtime which may deplete performance due its "middleman" position.

I was finally successful on building libtxc_dxtn from source for 32-bit Windows. The problem was Msys2 mingw-w64-i686-toolchain being buggy and failing to make a proper 32-bit DLL. I used mingw-w64-i686 standalone with dwarf exceptions and posix threading. The DLL is also much smaller, only 59 KB.

I'll try!

 

Can you release your package as a simple zip with loose files too? (for 32 AND 64 bit systems)

[pal1000]

Done. The portable version still includes the old cygwin binary and runtime for 32-bit apps, though, so please use the DLL from my previous post in place to benchmark as I decided to wait for your results. If you are wondering why I ditched the 64-bit cygwin binary, it isn't just because I was able to build libtxc_dxtn for 64-bit to begin with, but also it was causing instant exits or hangs with 100% CPU utilization on a hyperthread. And all this with an app that doesn't even actively use the extension. It just detects it to show up in a system information board.

Well, the dark mod - see my screenshot, is taken from The Dark Mod - is too heavy for MESA with my CPU (a poor i3 6300) but I will test other S3TC *OLD* games !

Remember to set the env variable to maximize old OpenGL (1.x ) applications compatibility!

Example (bat file) to properly launch the good old 1998 SiN

 

set MESA_EXTENSION_MAX_YEAR=2001
.\sin.exe
