Meta is set to unveil two cutting-edge prototype VR headsets — codenamed Tiramisu and Boba 3 — during SIGGRAPH 2025 in Vancouver, scheduled for August 10–14. Live demonstrations will take place on August 11 and August 14, giving attendees a first-hand look at the future of virtual reality.
Tiramisu – Hyperrealistic VR at Above-Retinal Resolution
Tiramisu is designed to push visual fidelity far beyond what current consumer headsets can deliver. It achieves an astonishing 90 pixels per degree (PPD) — surpassing the human eye’s approximate 60 PPD benchmark and dwarfing the Quest 3’s 25 PPD.
Key Features:
- 3.6× higher pixel density than Quest 3.
- 14× greater brightness for more vivid imagery.
- 3× higher contrast for lifelike shadows and highlights.
- Micro-OLED display technology producing ultra-sharp visuals.
However, this realism comes with trade-offs: the field of view is only 33° x 33°, the headset is bulkier, and its demanding visuals require high-end GPUs with advanced rendering techniques like DLSS 3 to run Unreal Engine 5 experiences smoothly.
Boba 3 – Expanding the Field of View
While Tiramisu focuses on unmatched clarity, Boba 3 is all about immersion through an ultra-wide field of view. It boasts 180° horizontal and 120° vertical vision, approaching the range of human eyesight and nearly doubling the Quest 3’s field of view.
Key Features:
- 4K x 4K resolution per eye with approximately 30 PPD.
- A lightweight build at around 660 grams, making it more wearable than bulkier designs.
- Compact design optimized for comfort during extended sessions.
Despite the impressive field of view, the resolution per degree is lower than Tiramisu’s, and rendering such a vast image still demands powerful PC hardware.
A Glimpse Into the Future of VR
Both headsets are research prototypes, not consumer products. They are part of Meta’s long-term mission to reach the “Visual Turing Test” — a level where VR visuals are indistinguishable from reality.
- Tiramisu is the pinnacle of visual clarity but sacrifices field of view and portability.
- Boba 3 offers unmatched immersion with a massive viewing range but slightly less detail per degree.
These prototypes serve as technology testbeds that could influence future Meta Quest generations, possibly informing the design of a Quest 4, Quest 5, or other next-gen VR hardware.
