Changes from my Forza Motorsport (2005) PC port work, on top of title/forza (afc5ee8). Experimental: tested by playing on one Windows PC (D3D11, XAudio2), menus and races.

What's in it

• Per-pixel W-buffer depth (RECOMP_D3D8_WDEPTH, on by default when the title uses W): the host interpolated W linearly in screen space, which made coplanar billboards z-fight (white wedges through the Mr. Clean adverts). The VS now passes a perspective-correct and a linear W, and the PS writes SV_Depth from them.
• Culling and polygon offset taken from title-recorded push buffers (RECOMP_PB_CULL, RECOMP_PB_POLYOFFSET).
• Launcher: on first start it asks for the player's own disc image (.iso/.xiso, XDVDFS), extracts the game and checks default.xbe against XBE_SHA1 (new recomp_add_launcher option).
• Stall watchdog (RECOMP_WATCHDOG_STALL=) that dumps the presenting thread's guest stack; long kernel waits are logged.
• Register promotion for hot functions (tools/recomp/regpromote.py, with tests).
• D3D8 texture, movie, state and audio fixes, plus F11 frame series + d3d8_replay options (--skip-draw, --draws, --list-draws).

Notes

• Some files keep their CRLF line endings, as upstream has them.
• The matching forza-recomp changes come in a separate PR.

Known open issue: Arcade/Free Run can hang on a white screen.

Thanks for the toolkit and the Forza groundwork!

Thanks! I'll take a look through and see what's worth pulling!

I hope your Forza recomp goes well! I did do some widescreen work but it requires extensive UI reworks
