BattlEye vs EAC vs Vanguard vs RICOCHET: The 2026 Anti-Cheat Comparison

Every DMA buyer asks the same first question: "will this work for my game?" The answer depends entirely on which anti-cheat the game runs — and in 2026, the four big ones (BattlEye, EAC, Vanguard, RICOCHET) are not equally hard and don't catch DMA cards the same way.

This post breaks down what each anti-cheat actually does, what's changed in 2025-2026, and which firmware tier matches each. We'll skip the marketing fluff — this is the same internal reference we use when answering customer questions.

How anti-cheats actually find DMA cards

Before comparing them, it helps to understand what they're all doing. Every kernel anti-cheat operates in layers, from low (boot chain) to high (in-game behavioral analysis). Different anti-cheats put weight on different layers.

The DMA card itself only really lives in layers 3-5. Layers 1-2 are system state (BIOS settings, Windows install) — no firmware can fix a dirty boot chain. Layer 6 is behavior — the cleanest firmware in the world won't survive obvious wallhacking.

The four anti-cheats, side by side

1. BattlEye + VAC — identity matters most

BattlEye is the oldest of the four (originally launched 2004). It's still actively maintained and used by some of the biggest games in the world — PUBG, Tarkov, Arma, R6 Siege. In 2025, Rockstar even added BattlEye to GTA Online.

BattlEye's primary detection vector is identity-based: it scans PCIe device VID/PID/serial, checks them against a remote ban list, and flags devices that have been seen before. The "ban list propagation" is fast — within minutes a flagged identity is blocked across every player's machine.

What beats BattlEye: a unique PCIe identity per build. If your DMA card reports a serial number that's never been seen before, BattlEye has nothing to match against. This is exactly what our Standard tier delivers — full Creative Recon3D donor config space (1024 DWORDs) with per-build randomized DSN and Subsystem ID.

VAC (Valve's anti-cheat for CS2) is in the same family for our purposes. Mostly user-mode, but the September 2025 "VAC Live" update added more aggressive behavioral checks. DMA still works fine in CS2 but expect longer review cycles.

2. EAC — the R/W consistency probe

EAC (Easy Anti-Cheat, owned by Epic) takes BattlEye's identity check and adds config-space write probing. EAC writes test values to specific config-space registers and reads them back — a real audio card responds with the exact bit pattern a real Creative Recon3D would. A "stub" DMA firmware that returns wrong values gets flagged.

This is what the writemask COE in our Advanced tier handles — every R/W register is mapped exactly to how the real donor card behaves. EAC's writes pass the consistency check.

EAC also runs behavioral detection — specifically aimbot-pattern recognition. Even with perfect firmware, obvious aim-snapping will get flagged. Keep aim natural.

3. Vanguard + NACE — system-state matters

Vanguard (Riot's anti-cheat for Valorant, League of Legends, TFT) is where things get serious. Vanguard runs a boot-time driver — it loads before Windows even starts. This means it can enforce things firmware alone can't fight: IOMMU enforcement, Secure Boot validation, signed-driver requirements.

Vanguard's main DMA-detection strategies in 2026:

• A/B functional tests: writes to BAR0 and expects real audio register responses (GCAP, WALCLK counter, CORB/RIRB queues). Our Ultimate tier's pcileech_bar_impl_hda_recon3d.sv RTL handles this.
• MSI interrupt validation: expects MSI interrupts to fire periodically (real audio card does ~100 Hz). Our Ultimate tier's pcileech_msi_generator.sv handles this.
• IOMMU enforcement: if your motherboard's IOMMU is enabled, Vanguard can deny DMA access to unauthorized devices. You must disable IOMMU/VT-d in BIOS.
• Honeypot memory regions: Vanguard places fake game data in known memory locations and watches who reads them. Firmware can't fix this — only careful cheat software can.

NetEase's NACE (Marvel Rivals, Naraka: Bladepoint) and EA's Javelin (Battlefield 6) are functionally similar — kernel drivers with A/B testing and behavioral detection. They share the same Ultimate-tier mitigations.

4. RICOCHET + Tencent ACE — the boot chain matters

RICOCHET (Activision's anti-cheat for Call of Duty) is the hardest mainstream anti-cheat in 2026. What makes it different is Microsoft Azure remote attestation. RICOCHET asks Microsoft's cloud to verify your TPM 2.0 chain — every driver loaded at boot, every signature, every Secure Boot measurement.

This is fundamentally different from the other anti-cheats. RICOCHET doesn't just look at your DMA card — it looks at your entire boot chain. If your TPM is dirty, Secure Boot is broken, or a software spoofer modified anything at boot, RICOCHET can flag the account regardless of how good the firmware is.

This is why Premium tier requires TPM 2.0 ON, Secure Boot ON, and a clean Windows install with no boot-time spoofer — the opposite of Ultimate tier's requirements. A single PC can run Vanguard OR RICOCHET, not both.

Tencent's ACE (Anti-Cheat Expert) for Delta Force added "DMA Shield" in December 2025 — functionally similar to RICOCHET's approach. Same TPM 2.0 + Secure Boot ON requirements. Delta Force lives on Premium tier alongside CoD for that reason.

Difficulty rating — how hard is each in 2026?

What changed in 2025-2026 (the parts most blogs miss)

The real takeaway

The thing most DMA buyers get wrong is treating "tier" as protection level — like Premium is just "more protected" than Standard. It's not. Each tier is tuned for a specific anti-cheat with specific system requirements. Premium's PCIe response timing jitter is useless against Vanguard. Ultimate's MSI generator is overkill for BattlEye.

Pick the tier matching the anti-cheat you're targeting:

• BattlEye / VAC titles → Standard
• EAC titles → Advanced
• Vanguard / NACE / Javelin titles → Ultimate (Secure Boot OFF, IOMMU disabled)
• RICOCHET / Tencent ACE titles → Premium (TPM 2.0 ON, Secure Boot ON, clean Windows)

If you're playing multiple games across these categories, you probably need two PCs — one configured for Vanguard's requirements, one for RICOCHET's. They can't coexist on the same machine because the BIOS/Secure Boot state is opposite.

Anyone selling a "one tier covers everything" product is either lying or doesn't understand what these anti-cheats actually do. Hopefully this post saves you a refund cycle.
