Running Fullscreen Games in a Window for Multitasking
You cannot natively convert a **Exclusive Fullscreen** game into a movable window. Exclusive mode takes direct GPU control. However, these solutions achieve the goal:
1. In-Game Settings (Best Performance)
Borderless Windowed / Windowed Fullscreen: Most modern games (DX11/12, Vulkan) offer this. Renders at desktop resolution, alt-tabs instantly.
Windowed Mode: Resizable window; may run lower res.
2. Third-Party Tools (Force Borderless)
Borderless Gaming (Free, Open Source):GitHub. Adds tray icon; right-click game → "Make Borderless." Works on 90% of DX9-DX11 titles.
Special K (Advanced):Kaldaien/SpecialK. Injects at launch; adds HDR, frame pacing, borderless, latency tools. Per-game profiles.
DisplayFusion (Paid / Free Trial): "Window Position" profiles; move game window to specific monitor/size via hotkey.
3. Chat Overlay Alternatives
Discord Overlay (Default: Shift+`): Pins chat/voice over *any* fullscreen game. Settings → Game Overlay → Enable.
Steam Overlay (Shift+Tab): Web browser, chat, guides inside game.
Xbox Game Bar (Win+G): Windows native; widgets for Discord, Spotify, Xbox Chat, performance overlay.
4. Hardware Solution
Second Monitor: Game fullscreen on Monitor 1; Discord/Browser/OBS on Monitor 2. Zero software overhead.
