| Aspect | Manual Accumulation | Motion Vector Method | |--------|---------------------|----------------------| | | Excessive ghosting | Smooth, accurate trails | | Performance | High memory bandwidth | Higher compute cost | | Artifacts | Heavy blur on static UI | Depth disocclusion errors | | Realism | Low (looks like fading) | Medium |
