Alternate frames across GPUs

Multi-GPU AFR

Alternate Frame Rendering: multi-GPU workstations alternate frames across GPUs to raise frame rate. For multi-GPU workstations and cloud render nodes.

Overview

AFR (Alternate Frame Rendering) lets a multi-GPU workstation assign consecutive frames to different GPUs, raising frame rate. Enablement is simple: launch args select the pipeline and GPU count — no project content changes. DawnEngine maintains this path with a Chinese UI.

This page covers single-machine multi-GPU AFR. For LED walls, CAVE, or multi-machine sync, see ClusterDisplay.

Key Capabilities

  • Alternate-frame rendering: rotate frames across GPUs for high-fidelity / high-resolution scenes
  • Zero content changes: no special level or material work for AFR
  • Cloud-render friendly: make better use of multi-GPU server nodes
  • Gains vary by scene: measure on your target project before relying on the uplift

Use Cases

  • High-end visualization and simulation where one GPU cannot hit the frame budget
  • Multi-GPU acceleration on cloud / Dawn Stream nodes

AFR works alongside Dawn Stream and World Streaming. For multi-display clusters, see ClusterDisplay.
