Bandicam

Bandicam is an incredibly powerful, heavily entrenched veteran titan that mathematically pioneered the "High-Performance Game Capture" market. It engineered a highly specialized DirectX/OpenGL hooking mechanism. It is the absolute weapon of choice for hardcore PC gamers and YouTube Let's Play creators who mathematically demand the ability to record a 4K video game at 120 frames per second without causing the game itself to drop a single frame of performance.
