Hollow Knight: Silksong on AnyPS5: Compatibility & Test Results

Current conclusion

Windows NVIDIA testing reaches opening gameplay at 60 FPS with patches and two opt-in switches. Windows AMD and Linux have separate results. The official table does not list this game as Playable.

Experimental result: extra patches, integration branches or local changes are required. Installing the tagged release does not establish this result.

Known issues

Windows · Not specified in NVIDIA report

Without APS5_WRITE_WATCH_IMPORTS=watch and APS5_STORE_AT_FLIP=1, the report records about 5 FPS, garbled backgrounds or a loading crash.
General GPU-wait and write-tracking fixes remain open; this is not a normal release setup.

Windows · 01.000.010 (master 01.02)

Boxed menu glyphs still require a local workaround.
The old allocator crash has no confirmed root cause; later clean runs do not prove a general fix.

Linux · Not specified in Linux report

Slow gameplay and cinematic flicker/A/V drift remain reported.
A later run hits unsupported st_size during first-area loading; a local fix awaited an in-game check.
The branch retains a bundled-libc workaround. #1586 and #1600 are open; #1601 is draft at review.
