→How to Improve Latency by Preventing GPU Buffering
In order to create a VR system with low latency, we have to consider every component and its individual involvement. Current LCD displays have fairly poor [[pixel switching time]] and [[refresh rate]]. This means that even if the latency on the host level is minimal, there still will be a noticeable delay between every image update. However, these issues will be easily solved as more advanced displays become prevalent.
The following picture illustrates the classic processing model used in VR applications:
