Its Anti-Piracy product is described as checking a player’s ownership and protecting a game’s launch; Anti-Tamper is intended to make a game’s code harder to inspect or modify. Whether either affects performance depends on the game and its implementation. The available evidence does not show that Denuvo always lowers FPS—or that it has no impact in every game.
What does Denuvo DRM do?
Denuvo is a set of game-protection products from Irdeto that publishers integrate into individual titles. The terms “Denuvo Anti-Piracy” and “Denuvo Anti-Tamper” describe related but distinct roles; neither should be used as a synonym for anti-cheat.
Anti-Piracy checks game ownership
Irdeto says its Anti-Piracy technology validates ownership with a game’s distribution platform, creates a hardware-bound token, and enables play on authorized devices. It describes the protection as reinforcing, rather than replacing, the platform’s own DRM. These are the vendor’s descriptions of its product, not a guarantee of identical behavior in every game.

Anti-Tamper makes modification harder
Irdeto describes Anti-Tamper as protection against reverse engineering and client-side changes, including debugging, memory editing, and code injection. Its listed techniques include code encryption, obfuscation, virtualization, integrity checks, and memory monitoring. Irdeto also positions Anti-Tamper as a layer that can hinder cheat creation. The company says its current Anti-Tamper offering operates in user mode and works without persistent internet connectivity; those claims should not be generalized to every Denuvo product or game configuration.

Does Denuvo lower FPS or affect performance?
There is no established universal answer. Irdeto says Anti-Piracy runs outside gameplay-critical paths such as startup and loading, and claims there is “no noticeable impact during play.” That is a vendor assurance, not an independent finding covering every title, build, or PC. Irdeto Anti-Piracy
An independent example points in the other direction from claims of inevitable FPS loss: in a September 2019 comparison of Batman: Arkham Knight, Ars Technica reported identical in-game frame-rate benchmark results and indistinguishable loading times between the tested Steam and Epic Games Store versions. That result applies to that game and test, not to all Denuvo-protected games. Ars also cautioned that one comparison could not settle the broader debate, and that updates removing DRM may include unrelated optimizations. Ars Technica’s Arkham Knight comparison

Frame rate, frame-time consistency, loading times, and crashes are separate outcomes. A result in one does not prove an effect in the others. To assess a claim about a particular game, look for comparisons using the same game build and patch, comparable hardware and settings, and a clear account of whether Denuvo was removed or merely bypassed. Check whether other game optimizations changed at the same time.
Does Denuvo require an internet connection? Can I play offline?
There is no single answer for every game. Connectivity and activation requirements depend on the title’s current implementation and terms. Irdeto’s statement that Anti-Tamper works without persistent internet connectivity does not establish that a specific game can be installed, activated, or played offline.

For example, a Ubisoft EULA for a particular game says DRM software and Denuvo Anti-Tamper are used, and that installation limits may apply, an online connection may be needed during installation or first launch, and some files may remain after uninstall. Those conditions belong to that game’s terms; they are not universal Denuvo requirements. Check the game’s current store listing and EULA for the applicable rules. Ubisoft game EULA hosted on Steam

Removal can be tied to a title-specific update rather than a universal change to how Denuvo works. In a notice updated December 4, 2025, KRAFTON said support for Denuvo on the PC version of Hi-Fi RUSH was scheduled to end at 00:00 KST on January 16, 2026. The notice required players to install the latest patch to continue playing and said the game’s own anti-tampering features would remain. This example shows that a removal can involve a patch and other protections may remain; it does not predict what another publisher will do. KRAFTON’s Hi-Fi RUSH notice
