Title

Dusk Diver 2 (PPSA06565)

Content version tested

01.000.000

AnyPS5 commit

main 44a59edc3a.

System tested

Linux 7.2.9 (Arch), Ryzen 9 7950X, Radeon RX 6650 XT, RADV Mesa 26.2.4, GCC, Release.

Furthest point

Menus (title, system settings, controller guide)

What is shown

From a fresh save with Cross pressed every 15 s, it shows "Press Any Button" on the title screen. It then goes through the first-start System settings (wireless controller, text display, lock-on options) with the "You can select the language and change game setting" prompt, and the Wireless Controller button guide by 175 s. The window title reports 2.4 FPS at 26 s, then 0.83 to 0.92 FPS for the rest of the run, including on these mostly static screens. No driver stop in 180 s.

The frame rate was not investigated, and no gameplay was reached in the 180 s.

Current blocker

Very low frame rate (about 0.9 FPS) from the title screen on, cause not investigated.

How it was run

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

Modules in sce_module are converted with the title. This dump has no PlayGo files, so it was run with APS5_PLAYGO_UNLISTED_CHUNKS=installed.

AI-assisted testing and report: yes, Claude Code.

Cause of the 0.9 FPS found, in diagnostic runs: about five draws per frame use buffer device addresses, and each takes about 190 ms to set up (resources, address-based builds). That is because the host-import budget collapses after vkAllocateMemory fails with -1000072003, so guest memory is copied through the CPU instead: 12.5 GB in a 90 s run. With draft #8091, which stops lowering the budget for that error, the same menus run at 11.8 to 13.0 FPS against 0.82 to 0.85 FPS on its exact parent, in a matched pair. Details and caveats: #8091 (latest comment).

AI-assisted: yes (Claude Code).
