  • @qqq @OpenStars before wow64 introduction, wine required 32 bit process and multilib to run 32 bit code, requiring 32 bit opengl/bulkan implementations
    But it is possible to run 32 bit code in 64 bit process.
    Wine in wow64 mode enforces 64 bit process to use only lower 32 bits address space and thunks 64 bit libraries via wine nt syscall interface to loaded 32 bit PE binaries. No multilib or even 32 bit process support required, 32 bit instructions executed as is. Also this allows using machine code translation layers (like fexemu) exposing native calls with same syscall interface.
    wow64 maybe still limitted because it does not allow calling native libraries directly and increases overhead. win32 TLS code is using same fs segment register as linux 64bit TLS and workarounds may have bigger overhead, than using multilib






  • @Breve i prefer spending couple hours to configure (and half-a-day to rebuild packages) to update my home linux system every half-a-year than using windows. And it seems, there is no windows alternative for non-IT-professionals now because every distro is broken. I still may recommend linux mint as windows alternative, but not sure it really will be better that windows because it’s ubuntu based and will catch all ubuntu bugs.
    Also, most binary distros build mesa with nouveau enabled, which breaks it. It links lingbm to glappi, which causes dependency hell. Also it adds some slow nouveau call to winsys implementation even if you do not have nvidia, shich causes big slowdown. And linked-in nouveau code in libgallium increases memory footprint This only should be used when you relly use nouveau, but most people replace it with binary blob or not using nvidia at all…
