I've tried all sorts: getting a Giga-capable router with 5G, setting up local wireless network where devices are connected to that 5G. Deactivating everything else. But the router isn't providing me with more than 7MB/s internal bandwidth (50Mbits/s), which matches the cap on our internet (due to old cabling in this block of flats).
Tried both Airlink and Virtual Desktop.
Maybe it's something silly like the LAN cable from the router to my PC is pre-Giga, or there's some annoying hidden 'energy save' feature on the router which is capping it. Or something i haven't thought of.
I'll have to take a closer look. 800Mb/s would be pretty amazing.
800 Mbps is not equal to 800Mb/s.Had another look: cable is Giga, Router settings fine except i was on a channel with a handful of neighbours so changed that. Got rid of other WLAN devices. Even disconnected internet. Set Airlink bitrate to max fixed rate of 200Mb/s (doesn't appear to offer higher values, even with dynamic). My 5G-WLAN does show a nice 780Mb/s status in the OS Control Panel.
In Task Manager when OCRServer is running it actually shows around 170Mb/s, which is near the 200Mb/s fixed-rate and much better than 50Mb/s. Yet HL:Alyx at my preferred High-graphics settings is still laggy and jerky (when compared to playing with cable). It's a little smoother on Low-settings, but some jerks/jitters still...jerkiness being a hefty immersion-killer in VR.
My GPU's memory is maxing out at 8GB, even causing a warning on the Alyx title screen. It's a 3060ti so quite capable. The OCRServer is taking around 35% of the GPU's usage with encoding jobs. My CPU (5600x) is a 6-core, maybe having 8 will help remove some of the jerkiness.
Maybe living in a huge complex of flats doesn't help either....wifi-interference and all that.
Conclusion: it's possible to use Quest 2 wireless for high-end Steam games, but there's some obstacles or compromises in getting there, at least for this user. USB-cable performance is stable and consistent, so will likely stick with that, especially for fast-paced shooters. The trick is being somewhat aware of where the wire is so you're not tripping over it...been fine so far.
800Mb/s is a whopping 6.4Gbps. Most people don't have gear to handle that, most likely only 1Gbps or 2.5Gbps. Sure, you can get 10 gig cards, but you need cat6e runs and Wifi 6/7 compatible AP's
Especially crazy considering the Quest 2 will top out at 1.2Gbps based on its 2x2 mu mimo config.
