Universal-FrameFX 1.4.1-linux-preview.2

Native Linux Vulkan/Wayland preview with an experimental Game Mode / gamescope path.

What's new vs preview.1

• Detect Game Mode (GAMESCOPE_WAYLAND_DISPLAY, gamescope session vars, UFX_FORCE_GAMEMODE)
• Capture preference in Game Mode: gamescope PipeWire node → portal ScreenCast fallback
• ufx-gamescope-launch.sh nested gamescope helper
• --session-info, --capture-fail-soft
• Docs: linux/docs/GAMEMODE.md, linux/docs/BLOCKERS.md

Still included

CSR 1.2, CSR 2.0 upscale, CSR 2.0 InterpFast FG (Desktop Mode portal capture)

Honest limits

• Deck Game Mode hardware QA: unverified (Lavapipe selftest only on the build box)
• CSR AI / FSR2+ / XeSS / LarkquillAI / DLSS: not on Linux yet
• This is a prerelease; Windows Beta10 remains the Latest release
