At SIGGRAPH 2025, Meta’s Reality Labs presented “Tiramisu”, a research prototype VR headset aiming for unparalleled visual realism. The OPALS team designed it to push the boundaries of image clarity and brightness, targeting what Meta refers to as the visual Turing test.The Verge
Tiramisu: The Visual Specs That Stand Out
- Angular Resolution: 90 pixels per degree (PPD)—3.6× higher than the Quest 3. This surpasses the 60 PPD benchmark considered “retinal resolution.”
- Brightness: Up to 1,400 nits—a vivid leap compared to Quest 3’s 100 nits
- Contrast: Approximately 3× higher than Meta’s current consumer headset lineup.
Trade-offs:
- Limited field of view (about 33° × 33°)
- Bulky and heavy design—best suited for research rather than consumer use
Why It’s Important
Tiramisu represents a bold leap toward creating VR visuals indistinguishable from the real world. Though it’s not commercially viable—due to form factor and cost constraints—it provides inspiration and direction for future consumer headsets, possibly shaping generation-after-next devices.
It’s a glimpse at tomorrow’s VR tech, prioritizing visual fidelity above all else.
Summary Table
| Feature | Spec Compared to Quest 3 |
|---|---|
| Resolution | 90 PPD (vs. 25 PPD) |
| Brightness | 1,400 nits (vs. 100 nits) |
| Contrast | ~3× higher |
| Field of View | Limited (33° × 33°) |
| Portability | Bulky and heavier (not consumer-ready) |
