What They Say
The Reality Check from The Information reported that at the recent Game Developers’ Conference, software engine developer Unity went into some detail about the improvements that dynamic foveated rendering could make to the performance of Sony’s forthcoming PlayStation VR2 headset. In a demo it showed a 14% improvement in frame rendering time and said that if found bigger gains with a dynamic eye-tracked process than with a fixed system.
What We Think
Regular readers will know that I have been a fan of gaze technologies and foveated rendering for a long time – a quick check back on my database shows that I first wrote about it back in 2015. The promise of the technique is to reduce the amount of processor power needed to render images by focusing the power where it is needed most. However, one of the gotchas to the idea is that doing the eyetracking well also takes a lot of processor power, which is one of the reasons it isn’t always adopted. Still, it’s good to see that work on the idea goes on. After all “If you know where I’m looking, you know what I care about”. (BR)
