How to Fix TAA Ghosting on Fast-Moving Objects

TAA ghosting is bad or missing reprojection. Writing motion vectors for everything that moves and tightening history rejection removes the trails behind fast objects.

How to fix it

1. Write motion vectors everywhere

Make sure skinned meshes, vertex-animated materials, and particles output motion vectors; anything that moves without them ghosts because TAA reuses stale history.

2. Strengthen history rejection

Tighten the neighborhood clamp / history rejection so the resolver discards old samples that no longer match the current frame for fast pixels.

3. Lower temporal weight for fast content

Reduce how heavily prior frames are weighted (or use an anti-ghosting response curve) so quick movement relies more on the current frame than blurred history.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
