| LIMITED | 10.1 | 0.3 | 14.6 | 21.2 | 23.7 | 7.6 | |
| 4. Configuration 3 streaming with two eye perspective views (data shows 1 view) | LAN | 16.1 | 5.1 | 77.3 | 73.9 | 79.7 | 89.3 |
| WI-FI | 13.9 | 2.9 | 79.7 | 59.3 | 66.7 | 63.0 |
The four configurations show progressively increasing optimization as measured during modification (peak performance).
