What is shown

The title starts at about 28 FPS, then aborts at 36 s, exit 134, when it first uses compute shader 0x20084d0000. Run with APS5_PLAYGO_UNLISTED_CHUNKS=installed.

Current blocker

The shader recompiler cannot resolve an image descriptor read through an address chosen between two constant-buffer reads:

compute shader 0x20084d0000: shader 0x20084d0000 stage 0: ShaderRecompiler::Recompile: GetImageResource dword 0 is not a valid runtime value; chain: LoadAddressU32@pc=0x00004244(GetAddressResource(Phi(Phi(ReadConstBuffer@pc=0x00000418(GetBufferResource(ReadConst(GetSrtResource, Immediate), ReadConst(GetSrtResource, Immediate), ReadConst(GetSrtResource, Immediate), ReadConst(GetSrtResource, Immediate)), ShiftLeftLogical32(ReadFirstLane(SelectU32(LogicalAnd, IAdd32, LoadBufferU32), Phi(LogicalAnd, LogicalAnd)), Immediate)), Phi(ReadConstBuffer@pc=0x00000418(GetBufferResource(ReadConst(GetSrtResource, Immediate), ReadConst(GetSrtResource, Immediate), ReadConst(GetSrtResource, Immediate), ReadConst(GetSrtResource, Immediate)), ShiftLeftLogical32(ReadFirstLane(SelectU32, Phi), Immediate)), Phi(ReadConstBuffer@pc=0x00000418(GetBufferResource(ReadConst, ReadConst, ReadConst, ReadConst), ShiftLeftLogical32(ReadFirstLane, Immediate)), ReadConstBuffer@pc=0x00003b70(GetBufferResource(LoadAddressU32@pc=0x00003b64, LoadAddressU32@pc=0x00003b64, LoadAddressU32@pc=0x00003b64, LoadAddressU32@pc=0x00003b64), Immediate)))), ReadConstBuffer@pc=0x00000418(GetBufferResource(ReadConst(GetSrtResource, Im …

I also tried two open descriptor-tracking PRs, each merged onto the same main. Neither changes the stop:

• fix(shader): fold descriptor web paths that hold the lane index or texels #12132 (fold descriptor web paths that hold the lane index or texels): the same error at pc=0x00003f28.
• feat(shader): resolve nested image tables through runtime pointers #7223 (resolve nested image tables through runtime pointers): the same error at pc=0x00004290.

How it was run

relinker --registry --rpath <build>/core/libs/libs eboot.elf app.elf

AI-assisted testing and report: yes.
