Diablo 4: Lord of Hatred Is Breaking Steam Records — But PC Players Are Hitting a Serious Problem
-

Diablo 4's Lord of Hatred expansion launched on April 28, 2026 to strong critical reception, with players praising its story, gameplay improvements, and endgame loop. The expansion has performed well enough to push Diablo 4 past its previous all-time peak player count on Steam — a remarkable achievement for a game that is three years old and a clear signal that Blizzard delivered something the community genuinely wanted. However, beneath the positive reception, a significant technical issue is emerging that is souring the experience for a meaningful portion of the PC player base. Reports of severe memory leak problems have flooded Reddit, with one detailed post by user Asmallman accumulating over 500 comments and 1,500 upvotes in under 24 hours — numbers that make it impossible to dismiss as an isolated hardware issue. The core complaint is consistent across affected players: the longer Diablo 4 runs, the more RAM it consumes, eventually leading to stuttering, freezing, and full crashes.
Restarting the game resolves the symptoms temporarily, but the cycle repeats after a few more hours of play — a frustrating pattern for anyone trying to sink meaningful time into a new expansion.What makes the situation more complicated is that this is not a new problem. Similar memory leak reports have surfaced on and off throughout Diablo 4's three-year lifespan, suggesting the underlying issue is deeply embedded in the game's architecture and genuinely difficult to resolve across the wide variety of hardware configurations the PC player base uses. Some programmers in the community have pointed out that memory leaks are notoriously hard to diagnose and fix precisely because they manifest differently depending on system specs, usage patterns, and session length. Asmallman's theory — that the game is hard-coded to cap its RAM usage at half of the system's total memory — has not been confirmed or denied by Blizzard. With an install footprint of 88.5 GB for the game and both expansions, plus an optional additional 83 GB for high-resolution assets, Diablo 4's optimization on PC clearly has room for improvement. Whether Blizzard addresses the issue with a targeted patch in the weeks ahead will be one of the most closely watched developments for the expansion's ongoing reception.
