High on Life (PPSA15388) on Linux

[Tamalero]

Tested

• Title: High on Life, PPSA15388, content 01.120.000, from the contributor's own console. The .esbak plain ELFs were relinked with --to-intel: eboot, sce_module/ (7 modules) and prx/ (27, mostly Wwise plugins).
• Host: Linux (CachyOS), Intel Core i9-14900K, RTX 4090 (NVIDIA 615.78.08).
• Build: main 895f47f, Release, GCC 16.2.1.
• Setting: APS5_PLAYGO_UNLISTED_CHUNKS=installed. The dump has no playgo-chunk.dat, and without it scePlayGo stops at start (fix(libScePlayGo): let users answer unlisted chunks #6236).
• Last update: 2026-10-22.

Status

Playable, slowly. The title boots, the menus run at 60 FPS, and a save continues into Blim City, which can be walked through and fought in. Rendering looks right in the areas visited: the house, Blim City and the desert.

Scene (warm caches)	FPS
Menus	60
Blim City, most views	7–13
Blim City, facing Blorto's Chef Stand	2.5–3.2

Open problems

• Mouse look lags 2–4 s at these frame rates. The sceMouse queue backs up. Fix: fix(libSceMouse): sum consecutive motion into the newest unread report #9982.
• Facing Blorto's Chef Stand, one compute shader takes ~96% of GPU time. It is a 16-byte-record buffer copy, about 17 ms per dispatch, around 12 per frame. Report: perf: High on Life: one 16-byte-record buffer copy compute shader takes ~96% of GPU time near Blorto's Chef Stand #9980.
• Intermittent startup crash while the save loads: a jump to a small address (0x468) or a general protection fault, both from the same title call path. 2 of 4 launches on 2026-10-22, and not seen in launches with no input during loading. Cause unknown; I'll report it separately once it reproduces on demand.
• Performance in general: most views are CPU-bound in the driver's per-draw work. Putting the process on the performance cores of a hybrid Intel CPU alone gave +41% in one scene.

Pull requests and local changes this title needs

• fix(libSceMouse): sum consecutive motion into the newest unread report #9982 (mouse lag), open.
• No local changes.
