CRS312-4C+8XG-RM
SWoS v1.11 (Not using v1.12 because it has a bug with 2.5gbps devices)
Network:
Desktop PC (10gbps) ==> CRS312-4C+8XG-RM ==> (2.5gbps) Wireless AP (802.11ax) ==> Oculus Quest 2
Symptom:
When using Virtual Desktop (Oculus App) to play a VR game wirelessly (rendered on PC, played on the the Quest 2), I get a bunch of network latency spikes. Every 4-6 seconds the latency spikes up, causes jitters in VR (which is very disorienting). Then it settles back down and is good for a few seconds before again spiking back up.
When not gaming, the ping time is 1ms between the devices. Latency is only an issue when the VR game is streaming.
Cause:
The CRS312-4C+8XG-RM is definitely the cause. When I swap it out for an old Netgear 1gbps switch, all latency problems disappear and the games play silky smooth.
Ping times (when not playing) are reliably 1ms. The problem only happens when streaming VR games. I *presume* it has something to do with the rate at which network traffic is coming through the switch...?
The Ask:
While swapping the switch is functional, that means that my desktop PC is no longer running at 10gbps. Does anyone have suggestions of what might be causing the problem? Or settings within SWoS that I should tinker with?
