Ongoing issue with steamvr being a laggy mess and even crashing randomly. As the title says, I have been having issues since December 2025. To give some background, I use mobile hotspot on my pc, and connect headset through that. Was working perfectly despite my motherboard being only wifi5. I have a quest pro. Was working as far back as 2024.

Previously using my current setup, even before getting a new wifi adapter everything was working perfectly. Moved to Texas, got a new internet and was gaming wired internet connection, connected headset through router. Everything worked perfect. Moved back to my current home, back on old internet, using mobile hotspot again, everything was working perfectly for a week. Not sure what changed but one night I started having random lag, mainly when entering steamvr overlay to look at stuff/desktops while playing vrchat. The lag would get worse and worse, especially in the overlay, to the point that steamvr would just stop, and eventually crash. No matter what virtual desktop settings I use, it continues to be a ongoing issue that it would have random lag, and or crash eventually. I managed to get it to be somewhat useable for my last few weeks at home, but lag remained and I had to drop virtual desktop settings down to minimum bandwidth etc. to keep it from crashing. I have completely nuked my pc and reinstalled everything five times. Even tried going to win11. Nothing has worked to fix the ongoing lag.
Just booted everything up for first time today after a month break, Steamvr remains completely unplayable, constant lag spikes, despite a fresh install of win10, all drivers, gpu drivers, and a upgraded wifi7 adapter. Headset is connected directly to pc through mobile hotspot, and this previously has worked perfectly. I have narrowed down it being a steamvr issue, everything works smooth, virtual desktop is smooth and everything works, it is only when in pcvr in steamvr that I experience intense lag, and eventual crash.

My system cpu, gpu, and ram are rarely every being pushed each barely hitting 60% utilization, gpu may hit 80% , when I have been able to get a game to launch and go into even demanding vrchat worlds with tons of stuff going on and avatars characters loaded, and the lag is even bad and unplayable in steamvr home where my system is basically at idle. I am at a loss as to what to do now to fix this issue and play vr again, I know it is not a hardware issue. I am assuming something in the update around December has broken steamvr. I have also tried connecting through routers that are wired, and not wired, to see if it is a issue with mobile hotspot, but no difference with steamvr.
