Release Notes:

GCC builds fixes only, MSVC builds users can ignore this release.

• Fixed regression in GCC x86 builds, which led to use of 387 floating-point arithmetic instructions instead of sse instructions. Reported - ViNi-Arco, fixed - Digger1955.

  • Added -msse and -msse2 to compiler_args. GCC requires either of them to be explicitly set in order to make -mfpmath=sse effective.

• Enabled multi-threaded Link-Time Optimization (-flto=auto) for GCC builds. Author - Digger1955

  • Does not affect compiler/linker output, speeds up LTO process. GCC requires -flto=auto to be explicitly set in order to activate multi-threading for LTO.

• Provided GCC SSE4.2-optimized (-march=x86-64-v2) builds of DXVK-GPLALL with Link-Time Optimization (-flto=auto), -O3 optimization level, optimizations for Intel CPUs (-mtune=intel) and additional optimizations. Author - Digger1955

  • Enabled optimizations for Intel CPUs (-mtune=intel) to futher increase performance in CPU-bound situations and to speed ​​up shader compilation on Intel CPUs.
    • Note: For any other CPU in GCC SSE4.2-optimized builds -mtune=generic is used, because GCC does not have tuning options for AMD CPUs.

• Provided GCC SSE4.2-optimized (-march=x86-64-v2) builds of DXVK-GPLALL with Link-Time Optimization (-flto=auto), -O3 optimization level, optimizations for up-to-date CPUs (-mtune=generic) and additional optimizations. Author - Digger1955

  • Explicitly set -mtune=genericto enable optimizations for any up-to-date CPUs. Up-to-date CPUs in GCC 15.1 are: AMD Zen and Intel Haswell or newer.
    • Note: It was already active, due to GCC behaviour, which does set -mtune=generic, if you specify -mtune=x86-64-v2.
