Have Windows 24H2 broke VR? (Pico4)

[Br.uNreaL]

So I have commented on several posts here about my sudden loss of “performance” on my VR titles while having a good pc:

CPU: ryzen 7700x
GPU: AMD 7900xt
RAM: 32GB 6000mhz
Headset: Pico4 with steamVR

I was away from my pc since before Christmas until last week and after a lot of updates, when I came back, I can’t get my 90fps/90hz on my games anymore, mainly Assetto Corsa, it’s like the fps are stuck round 75~80fps while GPU is around 50% usage…
For almost a year the pico4 steamVR combo was perfect, plug&play everytime I play… now It just doesn’t work like before…

I tried everything, going back to older drivers for the GPU and SteamVR but only worked for a day, next time I booted up its was back to fps being stuck… tried
Every combination possible of settings like motion smoothness and Pico connect settings etc etc etc but nothing works…
In Performance Panel from the Pico software it shows “game” at 16 to 20ms latency in red when I go in a game but I don’t know why…

I’m pretty sure that’s a problem from windows, and now I can’t even try Windows Mixed Reality or OpenComposite because it was discontinued and can’t be used anymore, what a big BS… I’m thinking about going back to the last windows version and see if that’s the issue…
