TSR = Temporal Super Resolution
Super Resolution = Upscaling/Downscaling

Und Temporal bedeutet, das es mehrere Frames als Infomationsquelle für das hochskalieren der resultierenden Frames verwendet.

Und Temporal bedeutet, dass es mehrere Frames ... verwendet.

Hätte ich so nicht gedacht. Macht aber Sinn.
Und dadurch hat TSR mehrere sich ergänzende Möglichkeiten:

TSR is not just AA, it’s AA + upscaling + reconstruction.

Scene is rendered at a lower internal resolution
Jittered samples are accumulated over time
History is often stored at higher-than-native resolution
Motion vectors guide reconstruction

TSR replaces:

TAAU
Screen percentage upscaling
Third-party spatial upscalers (in many cases)

From Unreal’s perspective, TSR is the default answer to both performance and quality scaling.

Gut zu wissen! 👍

DLSS / FSR (Temporal Upscalers)
These are temporal reconstruction techniques, similar in spirit to TSR, but:

• DLSS relies on ML inference
• FSR 2.x uses heuristic-based temporal accumulation

They share many of the same pros and cons as TSR:

• Excellent reconstruction
• Temporal stability
• Potential ghosting
• Non-trivial cost
