Sony's latest patent hints at a groundbreaking approach to reducing latency in future gaming hardware. The patent, titled "TIMED INPUT/ACTION RELEASE," focuses on predicting user inputs using AI and additional sensors to streamline command execution. This addresses the latency often introduced by advanced graphics technologies like frame generation, which, while boosting frame rates, can negatively impact responsiveness.
Sony's PlayStation 5 Pro already features PSSR (PlayStation Spectral Super Resolution), an upscaler capable of enhancing lower resolutions to 4K. However, newer technologies often introduce latency. Competitors like AMD and Nvidia have tackled this with Radeon Anti-Lag and Nvidia Reflex, respectively, and now Sony appears poised to enter the fray with its own innovative solution.
As detailed by Tech4gamers, the core of Sony's patent (WO2025010132) lies in predicting user inputs. Sony acknowledges the inherent latency between user input and system processing, leading to delayed commands and undesirable in-game consequences. Their proposed solution involves a machine-learning AI model that anticipates the next user command. This prediction is aided by an external sensor, potentially a camera observing the controller, to detect the player's intended input. The patent even suggests integrating this sensor directly into a controller button, possibly utilizing analog inputs—a technology Sony has championed in the past.
While the patent's specific implementation in a PlayStation 6 console is uncertain—patent filings rarely translate directly into final products—it strongly suggests Sony's commitment to minimizing latency. This is especially relevant given the growing popularity of frame generation technologies like FSR 3 and DLSS 3, which themselves contribute to latency. This technology would be particularly beneficial for fast-paced games demanding both high frame rates and low latency, such as twitch shooters.
The future application of this patent remains to be seen, but it signifies Sony's proactive approach to enhancing the responsiveness of future gaming experiences.
