I’m seeing persistent frame-pacing stutter in God of War Ragnarök on PS5 Pro.

• Firmware: 12.40.00.09
• Title ID: PPSA08329
• Game version: 06.006.000
• Direct-folder path: /data/homebrew/PPSA08329
• ShadowMountPlus: tested on v1.6test15-fix2 and v1.6beta16
• kstuff-lite: v1.09

The stutter is visible even in the main menu and repeatedly occurs at the same points in the intro. Other games, including Stellar Blade, run smoothly.

I already tried:

• A full clean reinstall
• A separately downloaded copy with identical relevant file hashes
• Disabling the game’s fakelib folder, which caused a black screen
• A separate FW 4.xx backport, which prevented the game from starting
• Updating and restarting ShadowMountPlus

The problem remains unchanged.

The log shows the per-game fakelib being mounted and also reports that kstuff was already disabled when the pause deadline was reached.

I have attached the current debug log, config, and autotune files. Could this be a PPSA08329-specific direct-folder, fakelib, or PS5 Pro/FW 12.40 compatibility issue?

Important update: I tested PPSA08329 v06.006 as an .exfat image. I have not tested it for an extended period yet, but the same sections that consistently stuttered with the direct-folder version were smooth in the .exfat version.

Correction: the .exfat image does not show any of the PS5 Pro Enhanced settings, even though the game information displays version 06.006. Therefore, it may not be running an equivalent updated/Pro-enabled build, so this comparison is not conclusive.
