Hi,

I'm doing a WiFi connection from my PC to the Oculus Quest3 and I bought a TP Link Archer AXE75 (5400 Mbps) - Black Friday sale. I'm thinking this roughly the speed of USB3.2. I plugged the PC in via RJ45 CAT 8 cable and connected the Quest to 6GHz WiFi; only 6GHz is enabled on this dedicated router for VR. I also connected the VR router via cable to main internet/WiFi (5GHz) router to get internet access. In Virtual Desktop 500 Mbps seems to be a limit on the video file (H264+) bitrate. Apparently the PC GPU encodes the VR view into a file/codec which is streamed to the Quest 3 which then decodes and displays it on it's (Quests') screens. I can't understand why Virtual Desktop is limited to 500Mbps when I went out and got router that specifically that could transfer at USB 3.2 bitrate. I might as well send the router back and downgrade to a cheaper slower model. I was hoping to get a 2500 Mbps connection with at least 1000 Mbps bit rate for video stream...If any one can shed some light would be very interested? Is it a hardware limitation on the Snap Dragon XR2 Gen 2 chipset that it only allows 500Mbps decode or is it purely software. I'm in two minds to send the router back and get the cheaper 3Mbps one apparently the up coming Valve Deckard (Index 2.0) will also be able to streaming over WiFi.

Realised and I hate to say it but VR is just so much more immersive than big TV, it's like watching a B&W silent movie with sub-titles and comparing it to a modern movie...I shouldn't have opened Pandora's box, too late now:)


Thanks

Is there any noticed latency-wise between the two? I can't imagine that anything with a bitrate needs more than 500Mbps, it's not like you're downloading large files to necessitate 1000Mbps or 2500Mbps for a video stream. Not even high-end 4K Blurays come close to that (topping out at ~128Mbps)

TBH It was a misunderstanding on my part. I was comparing it against the USB3.2 connection of 5Gbps so was trying equal that. I confused connection bandwidth with video bitrate which isn't the same as you rightly pointed out...
