Oculus Link bandwidth question.

If I understand correctly, "oculus link" bandwidth is only 150mbps. But USB 3.0 is capable to transfer from 600mbps to 5.0 Gbit/s. 
Is this Quest hardware(SoC) limitation? Or because of beta state? And it will be increased in the future.. 
P.s. And why old 
H.264? It would be better to use H.265..

It’s a limit of the decoding on the Quest hardware, but also it’s balanced against the work the GPU has to do encoding the stream (Carmack said they could possibly push the bitrate a little higher than they had). There are some settings that can be tweaked if you’ve got the extra horsepower on the PC side, as detailed in this thread

DK2, CV1, Go, Quest, Quest 2, Quest 3.

The encoding is done by the hardware encoder in the GPU, not by the CPU. You can see it in the advanced view of the task manager in the second tab and then selecting your GPU..

You can see in the sentence you quoted, I said GPU, not CPU.
