Capcom has quietly removed the Enigma DRM software from the PC version of Resident Evil 4 Remake, just 28 days after a controversial update swapped out the game's existing Denuvo protection and left players reporting significant performance drops. The change was spotted via SteamDB on March 3, with no accompanying statement from the publisher.
The episode began in early February, when Capcom pushed a small update to the three-year-old remake that replaced its Denuvo anti-tamper software with Enigma Protector. The update added no new content; it simply removed the Denuvo protection the game had carried since its 2023 launch and substituted Enigma DRM, which had a significant impact on performance. Player complaints followed quickly, prompting scrutiny from technology analysts.
Testing confirmed that on a Ryzen 5 3600 and RTX 4070 Super build, the introduction of Enigma Protector gutted CPU game throughput by 40%. While the gap narrowed to around 20% in combat-heavy sections where enemy AI introduced a separate bottleneck, the impact remained constant in other scenarios. On lower-power platforms like the Steam Deck the drop was particularly severe, with up to 30% frame-rate losses reported — hardware that previously ran the game at a stable 40–50 frames per second on medium settings was no longer able to hold above 30.
While the performance problems did not significantly dent Resident Evil 4 Remake's Steam lifetime user score of 95%, they did produce a noticeable spike in negative reviews. In a video published last month, Digital Foundry's Alex Battaglia was direct in his assessment. "Updating years old software with new DRM is just stupid," he said. "Like, stop, don't do that in the first place. Regardless of any possible performance degradations, what it'll do to your game is just piss off your audience."
Compounding the embarrassment, the pirated version of the game ended up running better than the Steam release — a scenario that cuts to the heart of a long-running argument about the practical value of anti-piracy software applied to older titles. Capcom had already stripped Denuvo from several of its other back-catalogue games, including Monster Hunter Rise, Resident Evil Village, Resident Evil 2 Remake, and Resident Evil 3 Remake.
The economics of Denuvo are worth understanding here. Research suggests Denuvo does protect legitimate sales to an estimated mean of 15 percent of total revenue and median of 20 percent, but there is little justification to employ it long-term — particularly given that it can have negative technical side effects and is generally disliked by users. Industry analysts have long noted that publishers typically allow Denuvo subscriptions to lapse once a game has moved through its primary sales window, since the ongoing licence cost outweighs any protection benefit for an established back-catalogue title. The decision to fill that void with Enigma, rather than simply dropping DRM altogether, is what drew the sharpest criticism.
The counterargument from publishers is not entirely without merit. Piracy does represent a genuine commercial concern, and DRM at launch — when a game generates the bulk of its revenue — has a defensible rationale. From a business standpoint, protecting a new release from piracy makes sense, though DRM has never been foolproof: those determined to pirate a game usually find a way around it, while legitimate buyers are often the ones dealing with the drawbacks. The broader question is whether applying that logic to a three-year-old game — one already cracked and regularly discounted on Steam — ever made commercial sense.
The vocal Resident Evil community made the removal of Enigma DRM possible, though Resident Evil 4 Remake is not the only Capcom game updated years after launch with the software, creating performance drops and breaking mod compatibility. After removing Enigma, the game's Steam page now shows it carrying no DRM software at all — an outcome few predicted when the controversy began.
Fan reaction on Reddit has been celebratory, though the underlying frustration remains. The episode invites a reasonable question about corporate governance: who approved a decision to add restrictive software to a well-regarded, heavily discounted game with an active modding community, and did any internal voice point out the obvious downside? Capcom has offered no answers. Its newest titles — including Monster Hunter Wilds, Street Fighter 6, and the upcoming Resident Evil Requiem — continue to use Denuvo at launch, suggesting the publisher remains committed to launch-window protection even as its back-catalogue strategy clearly needs refinement.
The pragmatic takeaway is straightforward. DRM at launch, applied to a game that represents serious commercial exposure, is a defensible business practice. Retroactively adding it to ageing titles in ways that degrade the experience for paying customers is not. Capcom's reversal suggests someone, eventually, reached the same conclusion. The more productive question now is whether that lesson sticks.
