v0.0.5: honest benchmark + README rewrite. Previous bench was unfair: bettercam.grab() and dxcam.grab() are one-shot modes that go straight to AcquireNextFrame; the typical usage is .start()+.get_latest_frame() which is much slower. v0.0.5's bench tests BOTH modes for each library. Result: on flip_demo's controlled 180 Hz source, bettercam's .start() mode only delivers ~125 fps and dxcam's only ~155 (rustcam ~170). On mover.py's realistic moving content, dxcam.start() drops to ~3 fps (basically broken) and bettercam.start() to ~60 fps with only 60% of returns being fresh. rustcam stays at ~150 fps with 99% changed. The README table now shows both modes side-by-side so the comparison matches reality, not benchmark theatre.
