QuickImageViewer (qIV)
A fast, GPU-accelerated image viewer for Windows.
Built on Direct2D, WIC, and native Win32 APIs. Single EXE, no installer(portable), no telemetry, sub-10 MB .
GPU bitmap cache — decoded images live in VRAM, preloaded in both directions
Background decode — worker thread pool; UI thread never blocks on IO
Instant startup — process stays resident in RAM after first launch (hide to tray with Esc, recall instantly)
Software fallback — GDI renderer for edge cases where Direct2D is unavailable
