العتاد Attestation via TPM 2.0 and Secure Boot in Modern الرياضات الإلكترونية Titles: Competitive Benchmark Analysis and العتاد Interactions

[Daniel Brooks]

I’ve been running frametime and latency benchmarks across my rig with various attestation setups, and I want to hear what you’re actually seeing in-game. When you enable Secure Boot plus TPM 2.0 PCR-based attestation (I’m specifically talking about the anti-cheat implementations in titles like Valorant’s Vanguard and FACEIT’s client), do you notice any frametime spikes during the initial integrity handshake, or does it settle once the root-of-trust is established? I’ve seen reports of the kernel-level measurement adding 2-4ms of input latency on cold boot, but my own tests show mostly consistent 1ms frametimes after warm-up.

Has anyone measured a real-world FPS or 1% low difference between a machine running with full attestation versus one where Secure Boot is disabled or set to Setup Mode? I’m especially curious about how the PCR extension writes interact with faster NVMe drives and whether you’ve seen scaling differences across CPU generations when the cryptographic verification runs on the platform controller hub. Also, does anyone here run multiple OS installs with different measured boot states, and how does that affect anti-cheat detection and your competitive matchmaking?

Short version: don’t stress about benchmarks, because there isn’t really one to worry about. TPM 2.0 and Secure Boot add essentially zero measurable overhead to gaming performance—they’re cryptographic verification routines, not compute
