"0.13 ms on a RX 9070 XT on RADV." "interesting data point is that transferring a 4K RGBA8 image over the PCI-e bus is far slower than compressing it on the GPU like this, followed by copying over the compressed payload." "200mbit/s at 60 fps" It's certainly a very different set of tradeoffs, using a lot more bandwidth.

Every millisecond counts here > When game streaming, the expectation is that we have a lot of bandwidth available. Streaming locally on a LAN in particular, bandwidth is basically free. Gigabit ethernet is ancient technology and hundreds of megabits over WiFi is no problem either. This shifts priorities a little bit for me at least.
