apitrace

If you encounter a problem with a game you might get asked to upload a trace file captured with apitrace.

To do that with this Standalone version:

• Download and extract a Windows binary release to a directory which is exposed via WINE (like $HOME/.wine/drive_c)
• Set the envvar WINEDLLOVERRIDES to d3d9.dll=n,b
• Set the envvar TRACE_FILE to the trace filename
• Copy apitrace's d3d9.dll (x86/lib/wrappers/d3d9.dll for 32bit games and x64/lib/wrappers/d3d9.dll for 64bit ones) to the directory where the main game executable resides
• Run the game, showcase the problematic spot, exit it again (keep it short, traces can get huge)
• Remove apitrace's d3d9.dll again
• Compress the trace file (preferably with apitrace repack -b original.trace compressed.trace) and upload to your favorite file hosting service

Example:

export WINEDLLOVERRIDES=d3d9.dll=n,b
export WINEDEBUG=fixme-all,+debugstr
export TRACE_FILE=d3d9.trace
cd ~/.wine/drive_c/Fallout
cp ../apitrace-msvc/x86/lib/wrappers/d3d9.dll .
wine falloutwHR.exe
rm d3d9.dll
wine ../apitrace-msvc/x86/bin/apitrace.exe repack -b d3d9.trace d3d9_repack.trace

Upon starting the game you'll get:

apitrace: loaded into C:\Fallout\falloutwHR.exe
apitrace: tracing to d3d9.trace

And afterwards you can replay that trace:

wine ../apitrace-msvc/x86/bin/apitrace.exe replay d3d9.trace
