What's new in v0.1.4

Full workaround parity with decky-lsfg-vk

Toggle	Env var(s) set
Disable vSync	MESA_VK_WSI_PRESENT_MODE=immediate
Base FPS Cap slider (0–60)	DXVK_FRAME_RATE=N
Disable vkbasalt	DISABLE_VKBASALT=1 (mutex with Force Enable)
Force Enable vkbasalt	ENABLE_VKBASALT=1 (mutex with Disable)
Gamescope WSI (disabled by default — conflicts with frame gen)	ENABLE_GAMESCOPE_WSI=0 DXVK_HDR=0
WoW64 for 32-bit games	PROTON_USE_WOW64=1
Disable Steam Deck Mode	SteamDeck=0
MangoHud Workaround	MANGOHUD=1
Zink (OpenGL → Vulkan)	__GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink

• Explicit VK_INSTANCE_LAYERS=VK_LAYER_OMFG_rust + VK_LAYER_PATH
• PRESSURE_VESSEL_FILESYSTEMS_RW set to expose layer dir inside Proton container

Config section collapsible

Config knobs section now has a collapse/expand toggle (default expanded), state saved to localStorage.

Smart clipboard (two modes)

Toggle in Usage section switches between:

• Inline: full env var string with active workarounds prepended
• Wrapper: /home/deck/.config/omfg/omfg-wrapper.sh %command%

Nerd Stuff modal

Tap Nerd Stuff to view raw omfg-live.toml and omfg-wrapper.sh with per-file copy buttons.

v0.1.3 — Workarounds section

What's new in v0.1.3

Workarounds section

New Workarounds panel in the plugin UI with two toggles that get prepended to the generated launch option string:

Disable vSync (MESA_VK_WSI_PRESENT_MODE=immediate)
Recommended for all frame generation use. Prevents Mesa's compositor vsync from interfering with the layer's frame insertion timing. Without this, the display sync interval fights the layer's inserted presents, causing stutter.

Disable vkbasalt (DISABLE_VKBASALT=1)
Enable if you see black screens or visual artifacts. vkbasalt post-processing can conflict with frame generation layers by processing the inserted frames.

When active, the launch option shown in the Usage panel and copied by the clipboard button automatically includes the enabled workarounds at the front:

MESA_VK_WSI_PRESENT_MODE=immediate DISABLE_VKBASALT=1 ENABLE_OMFG_RUST=1 OMFG_HOT_CONFIG_PATH=... %command%

Shared omfg.env store

Refactored the ~/.config/omfg/omfg.env file to be a proper multi-key store. The global layer disable flag and workaround flags now coexist without clobbering each other.

v0.1.2 — Full config parity + global toggle + log viewer

What's new in v0.1.2

Complete config parity with omfg-live.toml

All 37 OMFG environment variables are now surfaced in the plugin UI — previously 12 were missing:

Hot-reload (apply without restarting the game):

• OMFG_ADAPTIVE_MULTI_INTERVAL_THRESHOLD_MS — adaptive controller debounce interval
• OMFG_BFI_HOLD_MS — black frame hold duration (visible in bfi mode)
• OMFG_VISUAL_HOLD_MS — visual frame hold time (bfi / copy / history-copy)
• OMFG_BLEND_ORIGINAL_PRESENT_FIRST — blend mode frame order toggle
• OMFG_COPY_ORIGINAL_PRESENT_FIRST — copy mode frame order toggle
• OMFG_HISTORY_COPY_FREEZE_HISTORY — freeze history frame in history-copy mode
• OMFG_PRESENT_WAIT_TIMEOUT_NS — present-wait timeout (shown only when Present Wait is on)
• OMFG_BENCHMARK_LABEL — benchmark output label (shown only when Benchmark is on)

Startup-scoped (require game restart — clearly labelled ⚠):

• OMFG_SWAPCHAIN_IMAGE_BUMP_OVERRIDE
• OMFG_CREATE_DEVICE_DEBUG
• OMFG_CREATE_DEVICE_APPEND_TIMING_EXTENSIONS
• OMFG_CREATE_DEVICE_APPEND_TIMING_FEATURES

Global layer enable/disable toggle

New toggle at the top of the plugin panel. Writes OMFG_DISABLE_LAYER=1 to ~/.config/omfg/omfg.env, which the wrapper script sources. Disable OMFG for all games without touching individual launch options.

Layer log viewer

"View Layer Log" button reads the last 60 lines from ~/.local/share/omfg/logs/omfg.log and renders them inline in a scrollable monospace panel. Appears only when the layer is installed.

Wrapper script updated

The installed omfg-wrapper.sh now sources omfg.env and respects OMFG_DISABLE_LAYER, and explicitly sets OMFG_LAYER_LOG_FILE.

Tests

• 186 passing pytest tests, 100% backend coverage

v0.1.1 — Bug fixes + 100% test coverage

Bug fixes

• Critical: Fixed NameError on plugin load — WRAPPER_FILENAME was missing from import in installation.py, causing the plugin to crash immediately when Decky called check_omfg_installed
• Bug: Restored orphaned update_field method in configuration.py (definition line was dropped by a prior edit)
• UX: Fixed clipboard button falsely reporting "✓ Copied!" on Steam Deck — now uses execCommand('copy') fallback when navigator.clipboard is unavailable in Steam's local HTTP context
• Cleanup: Removed all unused imports across backend modules

Tests

• 176 passing pytest tests, 100% backend coverage across all 8 modules
• No real network calls or filesystem I/O — all mocked
• Runs in ~0.5 s
