Anyone else getting clapped by Vanguard despite running what should be a safe DMA setup? I've been digging into some strange behavior lately where custom firmware isn't enough to save the account. We're seeing a wave of account-level bans that don't immediately trigger an HWID strike, which points to some specific telemetry gathering by VGK.
The Investigation
I've been running tests with the latest MemProcFS library and supposedly "clean" firmware. The hardware itself seems to pass the initial boot and idle checks, but the moment the memory reading starts, the flag is raised.
Testing Breakdown
Detection Methodology
It's highly likely that Vanguard is monitoring specific memory access patterns or identifying artifacts left by the MemProcFS implementation. The fact that there is no HWID ban suggests these are manual flags or "suspicious behavior" triggers rather than a hard signature hit on the PCIe configuration space.
If you're running an external setup, you need to be extremely careful with how frequently you're polling the game state. Vanguard is clearly moving beyond simple PID/VID checks and looking at the actual impact of the hardware on the system bus.
Has anyone else noticed these non-HWID bans while using DMA recently?

Testing Breakdown
- DMA card connected but idle — No ban.
- DMA with firmware active (no software running) — No ban.
- Software launch + Active memory reading via MemProcFS — Account banned.

CR3 Handling: Vanguard might be detecting how we're resolving the Directory Table Base (DTB) or flagging unusual CR3 switching.
Library Signatures: If you're using a public wrapper for MemProcFS, the user-mode side of your software might be the weak link.
Latency Checks: Recent updates to VGK have improved their ability to detect timing discrepancies caused by DMA memory requests.
