new &wcap feature - allow to choose discrete vs integrated GPU to use for encoding. By default it will select discrete one. Using integrated may be useful for laptop users with nvidia optimus when you're recording low framerate / low complexity screen capture, as that uses less power, which means less heat & better battery usage. I recommend using iGPU only if you're on Skylake or newer Intel CPU, as older CPUs than Skylake have pretty poor performance & quality.
New version also includes minor fix for bad handling of minimized window capture. In such case no new frames are captured which means messed up timestamp or hanging of recording (if audio capture was also enabled). Now it will properly produce discontinuity in video stream.
