Valve's Steam has finally made its Windows 10 and 11 client a fully 64-bit application. The move comes as the company plans to sunset its 32-bit client, which will only receive updates until January 1, 2026.
These are "under the hood" changes, so you won't have to do anything but make sure you have the December update. Moving to a 64-bit client provides the app with better memory access, improved stability, and a stronger base for future updates, promising better performance.
Other fixes in the latest Steam update include Friends and Chat improvements, such as reporting suspicious or harassing messages within the chat window, alongside fixes for Big Picture Mode and Remote Play issues and other quality of life enhancements.
