Anyone currently digging into Vanguard KVM bypasses on Arch?
Trying to get a stable KVM/QEMU setup running for Riot's kernel beast. I've gone through the usual spoofing routine—timing ratios are tuned to 7, GPU capabilities are masked, and the VM detection score is sitting at a clean 2/91. On the surface, it looks solid, but vgk.sys is still catching something it doesn't like.
The Technical Wall:
The paradox here is that Vanguard's kernel driver (vgk) is clearly running in the background even when the client claims it's not initialized. This smells like a failed heartbeat check or a specific MSR (Model Specific Register) check that triggers a delayed flag rather than an instant kick. Most anti-cheats use these delayed kicks to make it harder to pinpoint exactly what leaked the VM state.
Has anyone else dealt with this 10-minute timeout recently? I'm wondering if they started checking specific MSRs that aren't properly emulated or if there's a new telemetry heartbeat that needs to be handled to keep the session alive.
Drop your findings if you've managed to stabilize the connection or found which specific register is causing the flag.

The Technical Wall:
- The client throws error VAN 79, demanding a reboot to initialize.
- After a fresh reboot, I can actually get into the game and start a match.
- Roughly 10-15 minutes in, I get clapped with VAN -128 and a kick to desktop.
- Re-launching without a full host/VM reboot cycles immediately back to VAN 79.

Host: Arch Linux
Hypervisor: KVM/QEMU
Detection Score: 2/91
Timing Ratio: 7
Status: vgk running, but client-side disconnects after a timed interval.
