Valve has finally launched a 64-bit Steam client for Linux in the beta branch, ending years of 32-bit limitations. This transition, announced earlier in 2026 with the RT3 client beta, aims to deliver a more consistent experience across Linux distributions. The update arrives alongside a new Achievement Sets feature, enabling developers to group base game, DLC, and other achievements by category.
A redesigned achievements page also makes it easier for players to track their progress. In a related move, Valve responded to Epic Games' new vibe-coded launcher beta with a mainline Steam update that significantly improved cold-start times, reinforcing Steam's competitive edge in the PC gaming market.
