Vapor - Steam Companion App

Tired of background apps draining your PC's resources during epic gaming sessions, or notifications popping up and ruining that perfect headshot? Vapor is your ultimate Windows companion, intelligently detecting Steam game launches and instantly applying your custom settings for unbeatable performance.

Forget the hassle of manually tweaking volumes, switching power plans, closing and relaunching resource-hungry apps, or toggling Windows Game Mode—Vapor handles it all seamlessly, tailored precisely to your preferences.

Concerned about apps that "optimize" your system without your input? You're not alone—and Vapor gets it. No one knows your setup better than you, so Vapor only automates the features you explicitly choose, with full transparency and easy customization beyond the defaults. What you select is exactly what it delivers—no surprises, just control. Under the hood, Vapor uses only standard Windows APIs that any productivity or gaming utility uses: reading Steam's public registry key to detect games, managing processes the same way Task Manager does, and adjusting audio and power settings through documented Windows APIs. Everything runs at normal user privilege level—no admin rights required, no kernel drivers, no system hooks.

Key Features:

• Smart Process Management: Automatically pauses selected apps to block distracting notifications (e.g., WhatsApp, Telegram) and resource hogs (e.g., OneDrive, Wallpaper Engine) when gaming begins, then relaunches them effortlessly upon exit.
• Audio & Power Tweaks: Customize system and game volumes, plus power profiles, to boost FPS and efficiency during sessions—and revert smoothly afterward.
• Hotkey Control: Instantly close or relaunch toggled apps for quick, on-demand optimization.
• Playtime Insights: Receive detailed session summaries, including playtime and Vapor's actions, for better awareness.
• Effortless Updates: Automatic version checks with a sleek system tray icon for simple management.

Built by a passionate gamer, Vapor is lightweight and designed for hassle-free setup. Download now and focus on what matters—dominating your games!
