On the other hand, an important consideration is that CUDA ISP does not offer RGBA64, needed for the Holoviz. This integrates the necessary conversions for RGBA64 to RGBA32 back and forth. | On the other hand, an important consideration is that CUDA ISP does not offer RGBA64, needed for the Holoviz.

This involves configuring the Jetson into a maximum performance mode. With the CUDA ISP in 24-bit colour depth. The latency lowered from 96 to 58 ms by optimizing the pipeline, leading to a 39.5% reduction. By preserving the 64-bit colour colour depth, the latency is still better, leading to 73 ms of glass-to-glass latency. | This involves configuring the Jetson into a maximum performance mode.
