Virtual Desktop Quest latency spikes

submitted 1 year ago byrayw_reddit

I just got set up with a dedicated ASUS RT-AX82U router (replacing TP-Link AX1500 which had WIRED lag spikes, for some reason) to use with a Quest 2. The router sits in the same room as the Quest itself, less than 10 ft away, and physically hooked up via ethernet to my PC. I have the latest firmware installed on the router, and set the transmit power to "Power saving", channel: 112 (DFS channel, zero interference), 802.11 AX only mode. I also changed the width to 80 MHz only.

I'm able to run Virtual Desktop at "high", 90 fps, 100 Mbps bitrate, H.264 codec and get around 29-35 ms total latency (VD v1.18). Latency wise seems okay I guess, but I seem to get noticeable micro-stuttering for some reason, especially in like Beat Saber where the notes are constantly streaming in...any ideas how to fix this? (Other than turning on "video buffering", which drastically increases latency, or dropping bitrate to 33 Mbps, which drastically kills image quality).

If I max it out to 150 Mbps bitrate, the latency shoots up to 40+ ms.
