Star Citizen on Wine (wine-tkg 11.3-1): LSFG layer no longer inserts in current runs

[Nipz-git]

Environment

• OS: CachyOS (Linux 6.19.6-2-cachyos)

• GPU: AMD Radeon RX 7900 XT (RADV)

• Game: Star Citizen (LIVE)

• Prefix: custom Wine prefix at /home/x/Games/star-citizen

• Wine runner in use: lug-wine-tkg-experimental-git-11.3-1

• LSFG-VK installed system-wide:

  • /etc/vulkan/implicit_layer.d/VkLayer_LS_frame_generation.json
  • /usr/lib/liblsfg-vk.so

  Note: default lug wine version causes a known black screen issue on launch with vulkan. Hence using the expiremental version

Problem

LSFG appears installed, but in current runs of Star Citizen under Wine, frame generation does not activate
lsfg-vk-report-20260305.tar.gz
, and Game.log no longer shows LSFG device-layer insertion.

Repro

1. Launch with:

   wineserver -k && /home/x/Games/star-citizen/sc-launch.sh
   

2. Enter game.
3. Observe no FG behavior / FPS uplift.

Expected

Game.log should include:

• Inserted device layer "VK_LAYER_LS_frame_generation" (/usr/lib/liblsfg-vk.so)

and frame generation should be active.

Actual

In the latest run (2026-03-06), Game.log shows Vulkan setup but no LSFG insertion line.
It also reports:

• Running process with elevated permissions. Vulkan implicit layer disabling not available. Falling back to manual layer disable.

Historical logs in the same install previously did show LSFG insertion, so this looks like a regression / compatibility issue with current runtime setup.

Additional notes

• RSI launcher logs contain abnormal game exits in some runs (code: 3 and code: 2147483905). (maybe from alt+f4s, didnt really look into this)
