Loads The Legend of Zelda: Ocarina of Time
RX 5700 (RDNA1, 8 GB): boots and plays the intro at ~15 fps, then hangs and crashes entering gameplay (VRAM exhaustion)
What happened
Worked: boots on build 117 (build 116 crashed during the shader build on this card). Title menu, intro and first cutscene render correctly. DualSense works.
Failed:
- Performance: steady ~15-16 fps (menu ~22). GPU 3D load ~94% and one emulator thread pinned at 100%. Lowering settings made no difference, so the bottleneck looks like the mesh-shader compute fallback plus emulated tensor ops (no cooperative_matrix on RDNA1).
- Audio crackles/cuts out and the picture freezes intermittently in the menu and cutscene. NVDEC GPU instead of CPU made the cutscene freezes shorter but did not fix them.
- After the first cutscene: black screen, hang (~8% GPU), then crash (ucrtbase.dll c0000409, subcode 7 = abort). Just before the hang: a burst of ~42 "Mesh emulation" pipelines, process VRAM ~13.3 GB on the 8 GB card, and "Image 4096x4096 ... is over the memory budget; allocating it anyway". Earlier: "texture format=0" asserts in format_lookup_table.cpp.
Settings: 1X res, Max Resolution (built-in) patch disabled, Dynamic FPS patch on, GPU accuracy Low, async shaders on, AA None, OoT AA No sharpening, post-processing off, Bilinear filter, VRAM usage Conservative, ASTC recompression BC3, handheld mode.
How far they got
Title menu and the first cutscene. Crashed on the transition from that cutscene into the first gameplay scene, on two boots.
Steps to reproduce
1. Build 117 PGO, Windows 11, AMD RX 5700 (driver 32.0.21045.16010).
2. Boot Ocarina of Time with an empty shader cache and start a new game.
3. Watch the first cutscene. When it ends and gameplay should begin, the screen stays black, the emulator hangs and then aborts.
