Valve published a new Steam Client Beta update on October 16, 2026, with a second round of startup performance improvements. The change comes days after Epic Games released the preview of its new launcher, described as "vibe-coded" and presented as faster than Steam on cold start.
What happened?
According to Valve's announcement in the Steam Client Beta group and reported by GamingOnLinux, the update includes "Second round of Steam startup performance improvements following shipping of prior improvements in public client". Other fixes cover service dialog errors, British Columbia dates, Steam Frame content, voice chat volume, and bugs on Linux and Steam Input.
Previously, a public update had already reduced cold start time in user tests to around 5.23 seconds, below the 5.47 seconds claimed by Epic in commissioned benchmarks.
Why it matters
Competition between launchers has reignited the debate on performance and AI-assisted development. Epic positioned its AI-assisted rewritten client as significantly faster. Valve's quick response shows that traditional optimizations can still maintain leadership in a core aspect of the user experience.
Results vary by hardware. GamingOnLinux noted that, even with large libraries, loading became "ridiculously fast" in personal tests.
