PCIe System RAM Fallback Detected

Total memory demand (10.42 GB) exceeds GPU physical capacity (8.00 GB). 2.42 GB is evicted across the PCIe bus into DDR system RAM, causing 10x memory access latency and severe frame stutter.

Memory Math Formula

Uncompressed RGBA Frame: 3840 × 2160 × 4 × 2B = 63.28 MB

Timeline Overhead: 3 layers × 63.28MB + Alpha = 253.12 MB

Temporal Nodes: 5 frames × Optical Flow = 3.80 GB
