- Selective neighborhood clamp: only modify history when there's actual
motion or disocclusion — static pixels pass history through untouched,
preventing jitter-chasing from the shifting variance box
- Tonemapped accumulation: Reinhard tonemap before blend compresses bright
edges so they don't disproportionately cause jitter
- Jitter-aware sample weighting: blend 3-20% based on sample proximity
- Soft MV dead zone: smoothstep instead of step avoids spatial discontinuity
- Aggressive velocity response: 30%/px motion, 50% cap, 80% disocclusion
- Terrain loading: radius 3 (49 tiles) to prevent spawn hitches,
processOneReadyTile for smooth progress bar updates
FSR2 temporal upscaling:
- De-jitter scene color sampling (outUV - jitterUV) for frame-to-frame
consistency, eliminating the primary source of temporal jitter
- Remove luminance instability dampening (was causing excessive blur)
- Simplify to uniform 8% blend (de-jittered values are consistent)
- Gamma 2.0 for moderate neighborhood clamping
- Motion vector dead zone: zero sub-0.01px motion from float precision noise
Loading screen:
- Reduce tile load radius from 3 to 2 (25 tiles) for faster loading
- Process one tile per iteration for smooth progress bar updates
- Motion shader: zero out sub-0.01px motion to eliminate float precision
noise in reprojection (distant geometry with large world coords)
- Accumulate: tighten neighborhood clamp gamma 3.0→1.5 to catch slightly
misaligned history causing ghost doubles
- Reduce max jitter-aware blend 30%→20% for less visible oscillation
- Add luminance instability dampening: reduce blend when current frame
disagrees with history to prevent shimmer on small/distant features
Adds a wowee-git PKGBUILD suitable for submission to the Arch User
Repository. Tracks the main branch HEAD; pkgver is auto-generated from
the commit count + short hash so no manual bumping is needed on new
releases.
Key design decisions:
- Real binaries installed to /usr/lib/wowee/ to avoid PATH clutter
- /usr/bin/wowee wrapper sets WOW_DATA_PATH to the user's XDG data dir
(~/.local/share/wowee/Data) so the asset path works without any
user configuration
- /usr/bin/wowee-extract-assets helper runs asset_extract pointed at
the same XDG data dir; users run this once against their WoW client
- Submodules (imgui, vk-bootstrap) fetched from local git mirrors
during prepare() as required by AUR source array rules
- vulkan-headers listed as makedepend (required by imgui Vulkan backend
and vk-bootstrap at compile time; not needed at runtime)
Note: stormlib is an AUR dependency (aur/stormlib). Users will need
an AUR helper (yay, paru) to install it, or install it manually first.
