WINE Experimental WOW64 crash log

Hi,

I build WINE latest gitlab master branch code in a 64bit-only Debian Stable
system.
I build it like this:

./configure --enable-win64 --without-x --with-wayland
--enable-archs=x86_64,i386 


However, any games using Directx crash before even starting (backtrace log
attached).

Is that expected at this point? Shouldn't many games work by now in
experimental WOW64 mode or is it still early days?

Thanks!

In my case works and many titles work too however some dont work in new wow64

I use this:

./configure --without-wayland --enable-archs=i386,x86_64

wayland wine still wip however personally maybe can change for ubuntu 26.04 

and --enable-win64 is dont needed in my case too

Can you tell me about some 32bit games that work in experimental wow64 mode for
you? I'd like to see what it's capable of on a 64bit-only system.

Please give some examples of games so that others can test.

This is likely related to https://bugs.winehq.org/show_bug.cgi?id=57103 and
fixed with the same patch.

No, it's not fixed by that patch. Possibly unrelated.

i have testing this mode some time ago* with xubuntu 24.04 x64 when you have
wine in this mode only give wine binary (on wine-staging produce wine64 binary)

*around since wine 9.4 when wine add: VK_EXT_map_memory_placed (this solve a
huge problem related stability (more notorious in 32bit apps), actually
suddenly crashes in most cases are solved in my case)

for test apps i use this command for launch appetizer (program for launch apps)

DXVK_HUD=devinfo,fps,version,api DXVK_FRAME_RATE=60 DXVK_LOG_LEVEL=none
DXVK_CONFIG_FILE=/home/linuxdesktopx64/dxvk.conf WINEDEBUG=-all wine
appetizer.exe

here show some gameplay videos with this (videos uploaded since around may 15
of this year):

Is that still an issue for you? Arch only ships new WoW64 for well over a year
by now and while there are still some broken applications, it generally works
fine.
